Abstract

A liquid crystal display device includes a liquid crystal display panel having a plurality of liquid crystal cells arranged in a matrix configuration, a printed circuit board having a drive circuit mounted thereon to drive the liquid crystal display panel, a supporter main for supporting the liquid crystal display panel, at least one hole formed in the printed circuit board, and at least one projected parts protruding from the supporter main, wherein the projected part is inserted into the hole to affix the printed circuit board to the supporter main.

Claims (25)

1. A liquid crystal display device, comprising:

a liquid crystal display panel having a plurality of liquid crystal cells arranged in a matrix configuration;

a printed circuit board having a drive circuit mounted thereon to drive the liquid crystal display panel;

a supporter main for supporting the liquid crystal display panel;

at least one hole formed through a thickness the printed circuit board; and

at least one projected part protruding from the supporter main,

wherein the projected part is inserted into the hole to affix the printed circuit board to the supporter main and the projected part has a projecting length less than the thickness of the printed circuit board.

2. The device according to claim 1 , wherein a diameter of the projected part is larger than a minor diameter of the hole by as much as about 0.02˜0.05 mm.

3. The device according to claim 2 , wherein the hole has an elliptical shape.

4. The device according to claim 1 , wherein the projected part includes a plurality of protrusions separated from each other by a first gap.

5. The device according to claim 4 , wherein the hole has an elliptical shape.

6. The device according to claim 5 , wherein the first gap extends along a direction parallel to a major diameter of the elliptical shaped hole.

7. The device according to claim 1 , wherein the hole has an elliptical shape.

8. A method of fabricating a liquid crystal display device, comprising:

providing a liquid crystal display panel having a plurality of liquid crystal cells arranged in a matrix configuration;

providing a printed circuit board having a drive circuit mounted thereon to drive the liquid crystal display panel and at least one hole formed through a thickness of the printed circuit board;

providing a supporter main for supporting the liquid crystal display panel and forming at least one projected part protruding from the supporter main; and

inserting the projected part into the hole to affix the printed circuit board to the supporter main,

wherein a projecting length of the projected part is less than the thickness of the printed circuit board.

9. The method according to claim 8 , wherein a diameter of the projected part is larger than a minor diameter of the hole by as much as about 0.02˜0.05 mm.

10. The method according to claim 9 , wherein the hole has an elliptical shape.

11. The method according to claim 8 , wherein the projected part includes a plurality of protrusions separated from each other by a first gap.

12. The method according to claim 11 , wherein the hole has an elliptical shape.

13. The method according to claim 12 , wherein the first gap extends along a direction parallel to a major diameter of the elliptical shaped hole.

14. The method according to claim 8 , wherein the hole has an elliptical shape.
