Abstract

A liquid crystal display is disclosed. The liquid crystal display includes a liquid crystal display panel including an upper glass substrate and a lower glass substrate that are disposed opposite each other with a liquid crystal layer interposed therebetween, a glass diffuser plate provided on a back surface of the liquid crystal display panel, an adhesive layer provided at an edge between the liquid crystal display panel and the glass diffuser plate, a light source provided at a back surface of the glass diffuser plate, and a cover bottom including a vertical portion that supports an edge of the glass diffuser plate at the back surface of the glass diffuser plate and is opposite to a side of the light source, and a horizontal portion that is extended from the vertical portion and is opposite to a back surface of the light source.

Claims (55)

1. A liquid crystal display, comprising:

a liquid crystal display panel including an upper glass substrate and a lower glass substrate facing each other with a liquid crystal layer interposed therebetween;

a glass diffuser plate disposed below a lower surface of the liquid crystal display panel;

an adhesive layer attaching the liquid crystal display panel and the glass diffuser plate at an edge thereof;

a light source disposed below a lower surface of the glass diffuser plate;

a cover bottom including a vertical portion that supports an edge of the glass diffuser plate at the lower surface of the glass diffuser plate and faces a side of the light source, and a horizontal portion that is extended from the vertical portion and faces a lower surface of the light source;

an adhesive member interposed between the vertical portion of the cover bottom and the edge of the glass diffuser plate; and

a support member facing at least one lateral side of the glass diffuser plate and covering at least part of the region between the liquid crystal display panel and the glass diffuser plate, and the support member disposed directly on the upper surface of the vertical portion of the cover bottom and fixed to at least one of the glass diffuser plate and the cover bottom and the liquid crystal display panel by the adhesive member,

wherein the support member has a light reflection capability, and

wherein the glass diffuser plate is in contact with the support member.

2. The liquid crystal display of claim 1 , wherein at least one side of the glass diffuser plate includes an edge having one of a round shape and a chamfer shape.

3. The liquid crystal display of claim 1 , wherein the glass diffuser plate is made of the same material as the lower glass substrate.

4. The liquid crystal display of claim 1 , wherein the first support member has a multi-layered structure.

5. The liquid crystal display of claim 4 , wherein a layer of the multi-layered structure disposed closest to the side of the glass diffuser plate has a light reflection capability.

6. A liquid crystal display, comprising:

a liquid crystal display panel including an upper glass substrate and a lower glass substrate facing each other with a liquid crystal layer interposed therebetween;

a glass diffuser plate disposed below a lower surface of the liquid crystal display panel;

an adhesive layer attaching the liquid crystal display panel and the glass diffuser plate at an edge thereof;

a light source disposed below a lower surface of the glass diffuser plate;

a cover bottom including a vertical portion that supports an edge of the glass diffuser plate at the lower surface of the glass diffuser plate and faces a side of the light source, and a horizontal portion that is extended from the vertical portion and faces a lower surface of the light source; and

a support member facing at least one lateral side of the glass diffuser plate and covering at least part of the region between the liquid crystal display panel and the glass diffuser plate, and

the support member fixed to at least one of the glass diffuser plate, the cover bottom and the liquid crystal display panel,

wherein the support member has a light reflection capability, further comprising:

a circuit unit attached to liquid crystal display panel; and

a printed circuit board electrically connected to the circuit unit,

wherein the printed circuit board is accommodated in a space provided by the vertical portion of the cover bottom,

wherein the vertical portion of the cover bottom comprises:

a first body having one end connected to one end of the horizontal portion and the other end extended toward the glass diffuser plate;

a second body having one end connected to the other end of the first body and the other end that is inclined at a predetermined angle and is extended toward the glass diffuser plate; and

a third body having one end connecting to the other end of the second body and the other end that is extended to the outside in parallel to the horizontal portion and supports the glass diffuser plate.

7. The liquid crystal display of claim 6 , wherein the printed circuit board does not protrude from a side of the liquid crystal display panel.

8. The liquid crystal display of claim 6 , wherein the vertical portion of the cover bottom comprises:

a fourth body having one end connected to one end of the horizontal portion and the other end extended toward the glass diffuser;

a fifth body having one end connected to the other end of the fourth body and the other end that is extended to support the glass diffuser plate and in parallel to the horizontal portion; and

a sixth body having one end connected to the other end of the fifth body and the other end that is inclined at a predetermined angle and is extended toward the horizontal portion of the cover bottom.

9. The liquid crystal display of claim 8 , wherein a height from the horizontal portion to the third body is substantially the same as a height from the horizontal portion to the fifth body.

10. The liquid crystal display of claim 8 , further comprising a reflective sheet accommodated in an inner space provided by the vertical portion and the horizontal portion of the cover bottom,

wherein at least one side of the reflective sheet is bent at a predetermined angle and is placed on at least one of the second body and the sixth body.

11. The liquid crystal display of claim 6 , wherein the support member is in direct contact with the lateral side of the glass diffuser plate.

12. The liquid crystal display of claim 6 , wherein the circuit unit includes a flexible film attached to at least one side of the liquid crystal display panel and driver integrated circuits mounted on the flexible films,

wherein the support member includes a second support member fixed to at least one of the upper glass substrate and the lower glass substrate, and

wherein the support member is disposed on at least one surface of the flexible film.

13. The liquid crystal display of claim 6 , further comprising:

a flexible film attached to the liquid crystal display panel, and

a plurality of driver integrated circuits mounted on the support member and flexible film,

wherein the support member includes a second support member fixed to at least one of the upper glass substrate and the lower glass substrate, and

wherein the second support member is a flexible film.

14. A liquid crystal display, comprising:

a liquid crystal display panel including an upper glass substrate and a lower glass substrate facing each other with a liquid crystal layer interposed therebetween;

a glass diffuser plate disposed below a lower surface of the liquid crystal display panel;

an adhesive layer attaching the liquid crystal display panel and the glass diffuser plate at an edge thereof;

a light source disposed below a lower surface of the glass diffuser plate;

a cover bottom including a vertical portion that supports an edge of the glass diffuser plate at the lower surface of the glass diffuser plate and faces a side of the light source, and a horizontal portion that is extended from the vertical portion and faces a lower surface of the light source; and

a reflective sheet disposed on the cover bottom and including a first portion parallel to the horizontal portion of the cover bottom and a second portion extended from the first portion with an inclined angle,

wherein the vertical portion of the cover bottom has three bodies that include one inclined body with respect to the horizontal portion of the cover bottom, and the second portion of the reflective sheet is attached onto the one inclined body of the vertical portion of the cover bottom, which provide a closed space by the horizontal and vertical portions of the cover bottom and the second portion of the reflective sheet.
