ABSTRACT:
A direct lighting type LCD apparatus includes lamps for generating a first light, a diffusing member for diffusing the first light and light reflected from a reflecting member to emit a second light having uniform brightness distribution, and a receiving member for receiving the lamps, the diffusing member and the reflecting member for reflecting the first light to the diffusing member. The lamps are arranged in the receiving member to be separated from the diffusing member at selected distances, respectively, which may be different from one another. The direct lighting type LCD apparatus may have brightness distribution which is controlled by varying the distances between the respective lamps and the diffusing member to improve quality of image display.
