ABSTRACT:
An LCD apparatus is provided. The LCD apparatus includes lamps for generating a first light, a diffusing member, and a receiving member. The diffusing member diffuses the first light from the lamps and reflected light to emit a second light having uniform brightness distribution. The LCD apparatus also includes an LCD panel receiving the second light and displaying images in response to the second light by use of liquid crystal, and a top chassis combined to the receiving member to secure the LCD panel onto the receiving member. The distances between the respective lamps and the diffusing member vary in association with positions of the respective lamps such that the closer to a central portion of the diffusing member a lamp is placed, the shorter a distance between the lamp and the diffusing member.
