发明名称 PLANE LIGHT EMITTING DEVICE, PROJECTION TYPE IMAGE DISPLAY DEVICE, AND DIRECT-VIEW IMAGE DISPLAY DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a plane light emitting device that can emit light emitted from a light source in plane shape with a uniform illuminance, with a short distance. <P>SOLUTION: The plane light emitting device uses a light guide body 1A (1B) which has a plurality of translucent base materials 2a, 2b that propagate inside the light emitted from light sources P1, P2 and a plurality of semi-transmissive reflection films (including a case of a reflection film) 3a-3j in which the plurality of translucent base materials 2a, 2b are arranged in one direction and which are interposed between each of the plurality of translucent base materials 2a (2b), 2b and reflect at least a part of light propagating inside the translucent base materials 2a, 2b as reflecting light and transmit the rest as transmission light, and in which the plurality of translucent base materials 2a, 2b form an emitting face to emit light toward the same direction and emit the light emitted from the emitting face of each translucent base materials 2a, 2b to have a uniform illuminance and emit from the emitting face. <P>COPYRIGHT: (C)2012,JPO&INPIT
