Abstract

A narrow bezel-type liquid crystal display device is provided which is made as narrow as possible on the outer area. The narrow bezel-type liquid crystal display device according to an embodiment includes a guide panel with a light leak prevention function. This narrow bezel-type liquid crystal display device can reduce light leakage in a non-display area because the guide panel corresponding to a non-display area of the liquid crystal panel is made in black by double injection molding.

First claim

What is claimed is:

1 . A liquid crystal display device comprising:
a liquid crystal panel including a display area and a non-display area; a cover bottom having a bottom surface and side surfaces; and a guide panel including a first portion provided within the cover bottom and a second portion connected to the first portion and extending over a part of the side surfaces of the cover bottom; wherein at least part of the non-display area of the liquid crystal panel is supported by the second portion of the guide panel.

2 . The liquid crystal display device according to claim 1 , wherein the liquid crystal panel includes a first substrate and a second substrate, the first substrate including the non-display area which is exposed by the second substrate.

3 . The liquid crystal display device according to claim 2 , wherein the liquid crystal panel includes an upper polarizer attached to the second substrate, the upper polarizer extending over at least one edge of the second substrate at a circumferential portion of the liquid crystal panel.

4 . The liquid crystal display device according to claim 1 , wherein a circumferential portion of the liquid crystal panel adjacent to the display area is attached to the cover bottom by an adhesive configured to block light.

5 . The liquid crystal display device according to claim 1 , wherein a part of the display area of the liquid crystal panel is supported by the side surfaces of the cover bottom.

6 . The liquid crystal display device according to claim 1 , further including a backlight unit mounted within the cover bottom, wherein a part of the backlight unit is supported by the first portion of the guide panel.

7 . The liquid crystal display device according to claim 1 , wherein the first portion of the guide panel has a rectangular frame shape.

8 . The liquid crystal display device according to claim 1 , wherein the first portion of the guide panel includes a high part having a first height and a low part having a second height, the first height being higher than the second height.

9 . The liquid crystal display device according to claim 1 , wherein the part of the side surfaces of the bottom cover which the second portion of the guide panel extends have a lower height than the remaining part of the side surfaces.

10 . The liquid crystal display device according to claim 1 , wherein the second portion of the guide panel has a squared bracket shape.

11 . The liquid crystal display device according to claim 1 , wherein the second portion of the guide panel is configured to block light.

12 . The liquid crystal display device according to claim 1 , wherein the cover bottom has injection holes formed in the bottom surface thereof corresponding to a position of the first portion of the guide panel.

13 . A method for manufacturing a liquid crystal display device, including:
forming a cover bottom having a bottom surface and side surfaces; forming a guide panel including a first portion within the cover bottom and a second portion connected to the first portion and extending over a part of the side surfaces of the cover bottom; and mounting a liquid crystal panel including a display area and a non-display area, wherein at least part of the non-display area of the liquid crystal panel is supported by the second portion of the guide panel.

14 . The method according claim 13 , wherein the first portion of the guide panel is formed by injecting resin through injection holes in the bottom surface of the cover bottom.

15 . The method according claim 13 , wherein in a first step of a double injection molding process, the first portion of the guide panel is formed and then, the second portion of the guide panel is formed on the first portion by injecting black resin in a second step of the double injection molding process.
