Abstract

A liquid crystal display (LCD) including: a display panel; a backlight unit to radiate light to the display panel; a mold frame surrounding the backlight unit and supporting the display panel; a housing to receive the display panel, backlight unit, and mold frame; and a resin unit provided between the display panel and the housing. A receiving groove is formed below the resin unit, by sloped surfaces of the mold frame and side walls of the housing.

Claims (33)

1. A liquid crystal display device, comprising:

a display panel, said display panel comprising an exterior surface, an interior surface opposite to the exterior surface, and a side surface connecting the exterior surface and the interior surface;

a backlight unit radiating light to the display panel via the interior surface;

a mold frame surrounding the backlight unit and supporting the display panel;

a housing accommodating the display panel, the backlight unit, and the mold frame, said housing comprising a side wall facing the side surface of the display panel;

a resin unit provided between the side surface of the display panel and the side wall of the housing, attaching the display panel to the housing; and

a receiving groove formed between the mold frame and the housing, and directly connected to the resin unit.

2. The liquid crystal display device of claim 1 , the housing including a bottom plate and the side wall that extends from the bottom plate.

3. The liquid crystal display device of claim 1 , wherein the resin unit directly contacts the display panel and the side wall.

4. The liquid crystal display device of claim 1 , wherein the mold frame has:

a support surface upon which the display panel is disposed;

a sloped surface that extends from the support surface to the side wall, and

the side wall of the housing and the sloped surface at least partially define the receiving groove.

5. The liquid crystal display device of claim 4 , wherein an adhesive sheet is disposed between the support surface and the display panel, and between the backlight unit and the display panel.

6. The liquid crystal display device of claim 1 , wherein the resin unit comprises at least one material selected from urethane acrylate, acrylate, and silicon.

7. A liquid crystal display device, comprising:

a display panel;

a backlight unit to radiate light to the display panel;

a mold frame surrounding the backlight unit, having a support surface that supports the display panel, and sloped surfaces that extend from the support surfaces;

a housing having a bottom plate and side walls, to receive the display panel, the backlight unit, and the mold frame;

a resin unit provided between edges of the display panel and the side walls, attaching the display panel to the housing; and

a receiving groove partially defined by the sloped surfaces of the mold frame and the sidewalls of the housing to contain an excess amount of a resin used to form the resin unit, and directly connected to the resin unit.

8. The liquid crystal display device of claim 7 , wherein the receiving groove has a V-shaped, widthwise cross-section.

9. The liquid crystal display device of claim 7 , wherein the resin unit has a higher elasticity than the display panel, so as to protect the display panel from impacts applied to the housing.

10. A liquid crystal display device, comprising:

a display panel, said display panel comprising an exterior surface, an interior surface opposite to the exterior surface, and a side surface connecting the exterior surface and the interior surface;

a backlight unit radiating light to the display panel via the interior surface;

a mold frame surrounding the backlight unit and supporting the display panel;

a housing accommodating the display panel, the backlight unit, and the mold frame, said housing comprising a side wall facing the side surface of the display panel; and

a resin unit molded between the side surface of the display panel and the side wall of the housing, attaching the display panel to the housing; and

a receiving groove formed between the mold frame and the housing, and directly connected to the resin unit.

11. The liquid crystal display device of claim 10 , further comprised of a groove disposed to receive resin residual from molding of the resin unit, formed between the mold frame and the housing.

12. The liquid crystal display device of claim 11 , wherein the receiving groove exhibits a V-shaped, widthwise cross-section.
