摘要： A lighting apparatus 10 comprising light sources 12a, 12b for emitting light, a plurality of light reflection portions 20 formed on the reflection side for reflecting light incident from the light sources, and a linear photoconductor 14 for causing the light to exit from the exit side opposed to the reflection side, the planes of the plurality of reflection portions being respectively tilted at angles which converge the light to the human eyes watching. Angles of the light reflection portions are set so that exit angles of light exiting from the linear photoconductor are required angles, whereby the lighting apparatus can have a uniform light intensity distribution. The application of the lighting apparatus can provide a liquid crystal display of good display characteristics.

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.
