Abstract

A liquid crystal display device includes a main support supporting a liquid crystal panel and a back light unit, a printed circuit board attached to the liquid crystal panel to provide driving signals to the liquid crystal panel, a separation part between the printed circuit board and the main support creating a gap therebetween, and a holder holding the printed circuit board and the main support together.

Claims

1. A liquid crystal display (LCD) device, comprising:

a liquid crystal panel;

a backlight unit;

a main support supporting the liquid crystal panel and the back light unit;

a printed circuit board attached to the liquid crystal panel to provide driving signals to the liquid crystal panel;

a separation part arranged between the printed circuit board and a main support and creating a space therebetween to dissipate heat from the printed circuit board; and

a holder holding the printed circuit board and the main support together.

2. The LCD device as claimed in claim 1, wherein the separation part is formed at the edge portion of any one of the main support and the printed circuit board.

3. The LCD device as claimed in claim 2, wherein the separation part is formed of plastic.

4. The LCD device as claimed in claim 1, further comprising at least a tape carrier package to electrically connect the liquid crystal panel to the printed circuit board.

5. The LCD device as claimed in claim 1, wherein the separation part is arranged on a rear surface of the main support.

6. The LCD device as claimed in claim 1, wherein at least an integrated circuit is provided to an outside surface of the printed circuit board.

7. A process for fabricating a liquid crystal display (LCD) device, comprising:

arranging a liquid crystal panel and a back light unit in a main support;

forming a separation part on one of a printed circuit board and the main support to dissipate heat generated from the printed circuit board;

attaching the printed circuit board to the main support such that a gap between the printed circuit and the main support is created by the separation part; and

providing a holder to hold the printed circuit board and the main support together.

8. The process as claimed in claim 7, wherein the separation part is formed at the edge portion of any one of the main support and the printed circuit board.

9. The process as claimed in claim 8, wherein the separation part is formed of plastic.

10. The process as claimed in claim 7, further comprising forming at least a tape carrier package between the liquid crystal panel and the printed circuit board to electrically connect them.

11. The process as claimed in claim 7, further comprising forming at least an integrated circuit on an outside surface of the printed circuit board.

12. The process as claimed in claim 7, wherein the separation part is formed on a rear surface of the main support.
