ILLUMINATION DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

An illuminating device comprises a pair of light sources and a rod-like photoconductor. The rod-like photoconductor includes a pair of planes of incidence entered by the light from the light sources, a reflection surface having a plurality of prisms and an exit plane located opposite to the reflection surface. The width between the reflection surface and the exit plane at the planes of incidence of the rod-like photoconductor is smaller than the width of the light sources in the same direction. As a result, the brightness distribution of the light exiting from the rod-like photoconductor becomes uniform. The illuminating device is combined with a plate-like photoconductor to make up a planar illuminating device. Also, the illuminating device is combined with a liquid crystal panel to make up a liquid crystal display apparatus. <IMAGE>
