摘要:PURPOSE:To obtain the thin, high-brightness plane light emitting device by arranging a light diffusing plate above photoconductors arranged on both sides of a linear light source, and arranging light diffusion transmission parts on the rever surface of the photoconductors and a light diffu reflecting plate on the rever surface where the light diffu transmission parts are formed. CONSTITUTION:Optical waveguide plates 2 are arranged as the transparent photoconductors on both sides of the linear light source 1, the light diffusing plate 3 is arranged above the optical waveguide plate 2, and a light absorption part 6 which has an area distribution almost proportional to an illuminance distribution is formed on the rever surface of the light diffusing plate 3. Further, light diffu transmission 5 are formed on the rever surface of the optical waveguide plate 2 while increasing in area with the distances from the light sources 1 and 1, and the light diffu reflecting plate 7 is arranged on the rever surface of the optical waveguide plate 2 where the light diffu transmission 5 are formed. Conquently, the brightness can be incread and the thickness of the structure is reducible.
