ABSTRACT:
Unit reflection areas (13) each consisting of one or plural recesses and projections (17) are formed on the surface of a reflection plate (11). Light incident into the reflection plate (11) and reflected by respective unit reflection areas (13) is emitted to the entire specified plane area (emission area (14)) established on a specified plane, which is like a band: ring. The emission area (14) is established so that overlap thereof with a shining area of light regularly reflected by a liquid crystal panel (18) is made slight. With such a construction, in a reflection plate that is used for a reflection type or semi-transmission type display device, light that is reflected in useless directions, is reduced, and light utilization efficiency of incident light-can be increased.
