A liquid crystal display device is provided to improve a radiation efficiency and lower an internal temperature of LCD, to enhance a screen display quality by forming a pattern of grid shape in the bottom cover and to prevent light leakage by bending of liquid crystal panel. A liquid crystal display device includes a light guide panel(111), lamp(113), lamp housing(115), a plurality of optical sheets(117), back light assembly, bottom cover(121) and liquid crystal panel. The light guide panel changes a path of light and emits light to a liquid crystal panel. The lamp is adapted in the left and right sides of the light guide panel to generate light. The lamp housing protects the lamp and reflects light towards the light guide panel. The pluralities of optical sheets are adapted on the light guide panel and diffuse light. The back light assembly has a reflective plate(119) and is adapted under the light guide panel. The bottom cover is adapted under the back light assembly and fixes the back light assembly and has a pattern of grid structure formed in a back face thereof. The liquid crystal panel is formed of a liquid crystal panel. |
