Abstract

A liquid crystal display (LCD) device includes an LCD panel, a printed circuit board, and a guide panel which supports the LCD panel and to which the printed circuit board is fixed, wherein the guide panel has at least one rib to hold the printed circuit board.

Claims (14)

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

an LCD panel;

a printed circuit board; and

a guide panel which supports the LCD panel and to which the printed circuit board is fixed, and

wherein the guide panel is provided with at least one upper rib, at least one lower rib and at least two PCB supporting plates,

wherein the upper rib includes first and second protrusions projected with in the upper surface of the guide panel, and third and fourth protrusions vertically bent in the end of each of the first and second protrusions to face the side surface of the guide panel,

wherein the lower ribs dispose the upper rib at locations facing each other,

wherein each of the PCB supporting plates is separated from the upper rib and the lower rib with a gap of not less than the printed circuit board thickness therebetween,

wherein one end of the printed circuit board insert into a space between the PCB supporting plate of the upper part and the third and fourth protrusions, while the other end of the printed circuit board insert into a space between the PCB supporting plate of the lower part and the lower rib.

2. The liquid crystal display device according to claim 1 , further comprising a tape carrier package that connects the printed circuit board to the LCD panel.

3. The liquid crystal display device according to claim 1 , wherein the at least one lower rib is formed thinner and slanted outward as it goes to an upper end thereof.

4. The liquid crystal display device according to claim 1 , wherein the at least one upper rib is combined to the guide panel in a hinge shape through an elastic member.

5. The liquid crystal display device according to claim 1 , wherein the at least one lower rib is combined to the guide panel in a hinge shape through an elastic member.

6. The liquid crystal display device according to claim 1 , wherein the at least one lower rib is shaped as any one of tetragonal protrusion, triangular protrusion, and circular protrusion.
