<P>PROBLEM TO BE SOLVED: To restrain in-plane luminance unevenness caused by luminance distribution of a light source in the vicinity of an incident end of the light source when a laser light source as a point light source is adopted as a sidelight type backlight. <P>SOLUTION: A first backlight unit 2 of a liquid crystal display 100 is formed by laminating two sets of plane light sources 200a, 200b including light sources 20a, 20b having red, green, and blue laser light sources, and light guide plates 21a, 21b having light-transmitting sections for generating linear laser light sources from the spot-like laser light sources 20a, 20b and fine optical elements 25a, 25b for irradiating linear laser light as illumination light to a back surface of the liquid crystal display element 1 in a normal-line direction of a display surface of a liquid crystal display element 1, and illumination light having uniform in-plane luminance distribution can be generated by overlapping light emitted from these plane light sources. A liquid crystal display for providing a compact image with high quality can be attained in this simple structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
