Abstract
Disclosed is a liquid crystal display (LCD) device having a good heat radiating function. Surface areas of a lower cover, an upper cover, and a guide panel are increased by forming grooves at the lower cover, the upper cover, and the guide panel. Heat generated from an optical source is rapidly radiated through the lower cover, the upper cover, and the guide panel having increased surface areas. This may prevent temperature increment of a backlight unit.
Claims7
A liquid crystal display (LCD) device, comprising:
- an LCD panel;
- a plurality of optical sources disposed at one or more sides of a lower part of the LCD panel to supply light to the LCD panel;
- a light guide plate disposed below the LCD panel to guide the light emitted from the optical source to the LCD panel;
- a guide panel for supporting the LCD panel and the light guide plate;
- a lower cover and an upper cover for assembling the LCD panel, the light guide plate, and the guide panel;
- and
- heat radiating members formed in at least one of the guide panel, the lower cover, and the upper cover to increase surface areas of the guide panel, the lower cover, and the upper cover to radiate heat generated from the optical source.
