ABSTRACT:
An image display apparatus includes a backlight unit including a plurality of light sources arranged in a flat, a reflecting portion for reflecting light from the light sources, a diffuser for diffusing the light from the light sources and the light reflected from the reflecting portion, and a chassis for maintaining or supporting the light sources, the reflecting portion and the diffuser; and a liquid crystal display unit which receives the light diffused by the diffuser of the backlight unit. Concave portions are formed in the chassis at positions corresponding to electrodes of the plurality of light sources, positions corresponding to light-emitting portions of the light sources are arranged in a flat, and a circuit for driving the liquid crystal display unit is provided on a rear surface of a planar portion of the chassis. Accordingly, it is possible to realize a thin lightweight backlight with high luminance and high luminance uniformity.
