Abstract

A liquid crystal display device (LCD) includes a liquid crystal panel displaying an image; a first transparent plate disposed on the liquid crystal panel; a second transparent plate disposed underneath the liquid crystal panel; a support member supporting the second transparent plate and the liquid crystal panel; and a fixing member disposed on the first transparent plate, the fixing member coupled with the support member to fix the liquid crystal panel and the first and second transparent plates in place, and to protect the liquid crystal panel and the first and second transparent plates.

Claims (19)

1. An LCD, comprising:

a liquid crystal panel displaying an image;

a first transparent plate disposed on the liquid crystal panel;

a second transparent plate disposed below the liquid crystal panel;

a support member disposed below the second transparent plate to support the second transparent plate and the liquid crystal panel; and

a fixing member disposed on the first transparent plate, the fixing member being coupled to the support member to fix and protect the liquid crystal panel and the first and second transparent plates,

wherein the fixing member covers four edge potions of the first transparent plate,

wherein the fixing member is contacted face to face with the four edge potions of the first transparent plate, and

wherein a lower surface of the first transparent plate is fully contacted face to face with a upper surface of the liquid crystal panel.

2. The LCD according to claim 1 , wherein the liquid crystal panel is one of a TN (Twisted Nematic) mode, an IPS (In Plane Switching) mode and a VA (Vertical Alignment) mode.

3. The LCD according to claim 1 , further comprising a backlight assembly disposed below the liquid crystal panel, for supplying light to the liquid crystal panel.

4. The LCD according to claim 3 , wherein the backlight assembly is a direct type.

5. The LCD according to claim 3 , wherein the backlight assembly is an edge type.

6. The LCD according to claim 1 , wherein the liquid crystal panel comprises:

a first substrate;

a second substrate spaced apart from the first substrate by a predetermined distance;

a liquid crystal layer disposed between the first substrate and the second substrate;

a first polarizer attached on the first substrate; and

a second polarizer attached below the second substrate.
