ABSTRACT:
A direct-emission backlight unit for use in an LCD device includes a plurality of elongate lamps at the rear of a light diffusion plate and a plurality of reflecting members arranged in a matrix on a rear reflecting plate. The reflecting members are disposed in the gap between adjacent lamps, and reflect light emitted by the lamps toward the diffusion plate for achieving a uniform luminance profile of the emission surface of the backlight unit.
