Abstract

A liquid crystal display apparatus includes a display panel, a light source module configured to provide light to the display panel, a receiving container receiving the light source module therein, and an adhesion member disposed between the display panel and the receiving container to couple the display panel to the receiving container. The adhesion member includes a base layer with a hollow pocket therein and an adhesion layer disposed on both surface of the base layer. When the display panel is deformed, the adhesion member conforms thereto. Thus, light-leakage of the display panel may be prevented and light characteristics of the liquid crystal display apparatus may be improved.

Claims (23)

1. A liquid crystal display apparatus, comprising:

a display panel;

a light source module configured to provide light to the display panel;

a receiving container receiving the light source module therein; and

an adhesion member disposed between the display panel and the receiving container to couple the display panel to the receiving container, the adhesion member comprising a base layer having a plurality of connected sidewalls, outer surfaces of the sidewalls forming outer surfaces of the base layer and inner surfaces of the sidewalls forming outer surfaces of a hollow pocket within the base layer, the adhesion member further comprising adhesion layers disposed on opposing surfaces of the base layer.

2. The liquid crystal display apparatus of claim 1 , wherein the adhesion member extends along an edge of the display panel.

3. The liquid crystal display apparatus of claim 2 , wherein a height of the base layer is from about 0.1 mm to about 1 mm.

4. The liquid crystal display apparatus of claim 2 , wherein the receiving container has a frame shape surrounding the display panel and the light source module, and comprises a protrusion part protruding from an inner side surface of the receiving container in a first direction toward a center of the receiving container, and wherein the display panel is disposed on the protrusion part.

5. The liquid crystal display apparatus of claim 4 , wherein the receiving container comprises a recess on an upper surface of the protrusion part.

6. The liquid crystal display apparatus of claim 5 , wherein the adhesion member is disposed in the recess of the receiving container.

7. The liquid crystal display apparatus of claim 4 , wherein the receiving container further comprises a supporting part extending in a direction perpendicular to the first direction, so as to surround a side of the display panel.

8. The liquid crystal display apparatus of claim 7 , further comprising a protection window that is coupled to the supporting part and that covers a display area of the display panel.

9. The liquid crystal display apparatus of claim 8 , wherein the display panel is coupled to the protection window by an adhesive, the adhesive comprising at least one of acrylic resin, rubber resin, urethane resin, silicon resin, polyvinylether resin, phenol resin, urea resin, melamine resin, epoxy resin and polyester resin.

10. The liquid crystal display apparatus of claim 1 , the light source module comprises:

a light source configured to generate light;

a light guide plate positioned to receive the light from the light source;

a reflection layer disposed under the light guide plate; and

an optical sheet disposed on the light guide plate.

11. The liquid crystal display apparatus of claim 10 , wherein the light source module is disposed under the protrusion part.

12. The liquid crystal display apparatus of claim 1 , wherein the base layer comprises polyethyleneterephthalate.

13. The liquid crystal display apparatus of claim 1 , the display panel comprises a display area configured to display an image and a peripheral area surrounding the display area, wherein the adhesion member is disposed under the peripheral area.

14. The liquid crystal display apparatus of claim 1 , wherein the base layer comprises a plurality of the hollow pockets horizontally spaced apart from each other.

15. The liquid crystal display apparatus of claim 1 , wherein the base layer comprises a plurality of the hollow pockets vertically spaced apart from each other.
