Abstract

A display device including a rear chassis; a light source module installed on the rear chassis, the light source module being configured to emit light; a diffuser plate provided in front of the light source module, the diffuser plate being configured to diffuse the light emitted by the light source module; a liquid crystal panel provided in front of the diffuser plate, the liquid crystal panel being configured to display an image; a front chassis covering a side surface of the liquid crystal panel and a side surface of the diffuser plate; a middle mold provided between the front chassis and the rear chassis, the middle mold being coupled to the rear chassis and the diffuser plate; and a first adhesive provided between the diffuser plate and the middle mold, the first adhesive bonding the diffuser plate being to the middle mold.

Claims (54)

1. A display device comprising:

a rear chassis;

a light source module installed on the rear chassis, the light source module being configured to emit light;

a diffuser plate provided in front of the light source module, the diffuser plate being configured to diffuse the light emitted by the light source module;

a liquid crystal panel provided in front of the diffuser plate, the liquid crystal panel being configured to display an image;

a front chassis covering a side surface of the liquid crystal panel and a side surface of the diffuser plate;

a middle mold provided between the front chassis and the rear chassis and coupled to the rear chassis and the diffuser plate;

a first adhesive provided between the diffuser plate and the middle mold, the first adhesive bonding the diffuser plate to the middle mold; and

a second adhesive provided between the diffuser plate and the liquid crystal panel, the second adhesive bonding the diffuser plate to the liquid crystal panel,

wherein the middle mold further comprises an inserting groove into which a bent portion of the rear chassis is inserted and a fastening groove, and

wherein a fastening member passes through a fastening hole of the rear chassis and is inserted into the fastening groove.

2. The display device of claim 1 , wherein an outermost surface of the middle mold is coplanar with the side surface of the liquid crystal panel, or is located within a perimeter defined by the side surface of the liquid crystal panel.

3. The display device of claim 1 , wherein the front chassis comprises:

an inner side surface facing the side surface of the liquid crystal panel, the side surface of the diffuser plate, and a side surface of the middle mold, and

an outer side surface opposite to the inner side surface, and

wherein the inner side surface extends parallel to the outer side surface.

4. The display device of claim 1 , wherein the second adhesive comprises ultraviolet (UV) resin configured to be applied in a liquid state and hardened by a UV ray.

5. The display device of claim 1 , wherein the first adhesive comprises a transparent substance with 90% or more of light transmittance so that light is transmitted between the diffuser plate and the middle mold through the first adhesive.

6. The display device of claim 1 , wherein the liquid crystal panel is bonded to the diffuser plate by the second adhesive, and

wherein the diffuser plate is bonded to the middle mold by the first adhesive.

7. The display device of claim 1 , wherein the light source module comprises:

a plurality of light sources configured to emit light toward the diffuser plate,

a substrate on which the plurality of light sources are mounted to face the diffuser plate, and

a reflecting sheet provided on the substrate, the reflecting sheet being configured to reflect light emitted from the plurality of light sources and light reflected from the diffuser plate back toward the diffuser plate.

8. The display device of claim 7 , wherein the light source module further comprises a plurality of lenses mounted on the substrate and covering the plurality of light sources, the plurality of lenses being configured to diffuse light emitted from the plurality of light sources.

9. The display device of claim 1 , further comprising a chassis adhesive bonding the front chassis to a side surface of the middle mold.

10. A display device comprising:

a rear chassis;

a light source module installed on the rear chassis, the light source module being configured to emit light;

a diffuser plate provided in front of the light source module, the diffuser plate being configured to diffuse the light emitted by the light source module;

a liquid crystal panel provided in front of the diffuser plate, the liquid crystal panel being configured to display an image;

a front chassis covering a side surface of the liquid crystal panel and a side surface of the diffuser plate;

a middle mold provided between the front chassis and the rear chassis and coupled to the rear chassis and the diffuser plate;

a first adhesive provided between the diffuser plate and the middle mold, the first adhesive bonding the diffuser plate to the middle mold; and

a second adhesive provided between the middle mold and the liquid crystal panel, the second adhesive bonding the middle mold to the liquid crystal panel,

wherein the middle mold further comprises an inserting groove into which a bent portion of the rear chassis is inserted and a fastening groove, and

wherein a fastening member passes through a fastening hole of the rear chassis and is inserted into the fastening groove.

11. The display device of claim 10 , wherein the middle mold comprises a first adhesion surface and a supporting projection protruding toward the liquid crystal panel and having a second adhesion surface.

12. The display device of claim 11 , wherein the first adhesive provided on the first adhesion surface and the second adhesive is provided on the second adhesion surface.

13. The display device of claim 12 , wherein the supporting projection is provided next to a side surface of the diffuser plate, and

wherein the supporting projection is bonded directly to the liquid crystal panel by the second adhesive.

14. The display device of claim 10 , wherein an outermost surface of the middle mold is coplanar with the side surface of the liquid crystal panel, or is located within a perimeter defined by the side surface of the liquid crystal panel.

15. The display device of claim 10 , wherein the front chassis comprises:

an inner side surface facing the side surface of the liquid crystal panel, the side surface of the diffuser plate, and a side surface of the middle mold, and

an outer side surface opposite to the inner side surface, and

wherein the inner side surface extends parallel to the outer side surface.

16. The display device of claim 10 , further comprising a third adhesive bonding the side surface of the diffuser plate to the middle mold,

wherein a rear surface of the diffuser plate is bonded to the middle mold by the first adhesive.

17. The display device of claim 1 , further comprising a chassis adhesive bonding the front chassis to a side surface of the middle mold.

18. The display device of claim 10 , wherein the light source module comprises:

a plurality of light sources configured to emit light toward the diffuser plate,

a substrate on which the plurality of light sources are mounted to face the diffuser plate, and

a reflecting sheet provided on the substrate, the reflecting sheet being configured to reflect light emitted from the plurality of light sources and light reflected from the diffuser plate back toward the diffuser plate.

19. The display device of claim 18 , wherein the light source module further comprises a plurality of lenses mounted on the substrate and covering the plurality of light sources, the plurality of lenses being configured to diffuse light emitted from the plurality of light sources.
