Abstract

Disclosed is an LCD apparatus including a receiving container for receiving a light guide plate and a lamp assembly, a first chassis for fixing the light guide plate and an LCD panel, and a second chassis for fixing the first chassis and the LCD panel. The receiving container and the first and second chassis are made of metal material so that the LCD apparatus may have reduced size and weight.

Claims

1. An LCD apparatus comprising:

a light guide plate including a light reflecting surface, a light emitting surface opposite to the light reflecting surface and a side surface;

a first chassis including a sidewall and receiving the light guide plate, the first chassis being a vertically unitary and indivisible unit;

a second chassis disposed over the first chassis, a first portion of the second chassis making direct contact with the sidewall of the first chassis;

an LCD panel assembly disposed over the first chassis and facing the light emitting surface, the LCD panel assembly being guided by a guide member of the second chassis to be fixed to the first chassis;

a third chassis disposed over the first chassis, pressing an edge portion of the LCD panel assembly, outwardly combined with the side wall of the first chassis and the second chassis, and making direct contact with both a second portion of the second chassis and the sidewall of the first chassis.

2. The LCD apparatus of claim 1, wherein the light guide plate is disposed between the first chassis and the second chassis.

3. The LCD apparatus of claim 1, wherein the second chassis presses an edge portion of the light emitting surface.

4. The LCD apparatus of claim 3, wherein the second portion of the second chassis is near the first portion of the second chassis.

5. The LCD apparatus of claim 1, wherein the third chassis makes direct contact with an upper surface of the sidewall of the first chassis.

6. The LCD apparatus of claim 5, wherein the third chassis makes direct contact with an outer surface of the sidewall of the first chassis.

7. The LCD apparatus of claim 1, wherein the guide member guides each of four corner portions of the LCD panel assembly.

8. The LCD apparatus of claim 7, wherein the guide member includes a plastic-based material.
