发明名称 IMAGE DISPLAY DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To obtain an image display device with a wide color reproduction area and without color unevenness and luminance unevenness. <P>SOLUTION: The image display device has: first and second light sources (17, 18) which alternately generate first and second illumination light beams having mutually different spectral characteristics; a diffusion light guiding member (15) which diffuses the light beams from the first and second light sources and a light valve (16) which controls transmissivity or reflectivity to the illumination light beams from the diffusion light guiding member according to a color signal constituting an image signal. Each of the first and second light sources has light emission means (11, 13) having a plurality of kinds of luminous bodies (11r, 11g, 11b, 13r, 13g) which emit light beams in different colors, respectively and color mixture light guiding members (12, 14) for mixing light beams in different colors from the light emission means (11, 13) and guiding the light beams to the diffusion light guiding member (15). <P>COPYRIGHT: (C)2006,JPO&NCIPI
