Abstract:
A linear illumination device comprising:an optical waveguide member for guiding light incident on a first light incident surface of said optical waveguide member and emitting the light from a thin and long light emitting surface thereof, said light emitting surface being located so as to be opposed to said first light incident surface; a blue light source made of an electro luminescent element emitting blue color light as a surface emitting light source provided on a surface selected from said first light incident surface and a second light incident surface adjacent to a longer side of said light emitting surface; a red light source made of light emitting diode emitting red color light as a point light source provided on a surface selected from said first light incident surface and a third light incident surface adjacent to a shorter side of said light emitting surface; and a green light source emitting green color light provided on a surface selected from said first light incident surface, said third light incident surface and a fourth light incident surface opposing to said second light incident surface.
