<p><P>PROBLEM TO BE SOLVED: To provide a planar light-emitting device with the number of light sources reduced and capable of obtaining a planar light source with little luminance unevenness and high uniformity, even with a small number of light sources. <P>SOLUTION: The planar light-emitting device includes light sources 2, and light guides 11 with a thickness arranged in extension in a flat plate shape along a direction away from the light sources 2 with the light sources 2 as a center. A side face of the light guide 11 opposed to the light sources 2 is to be a light-incident face 11a, one of the faces in a thickness direction of the light guide 11 is to be a light-emitting face 11b, and a plurality of reflecting faces 12 making light entering from the light sources 2 into the light guide 11 through the light-incident face 11a emit from the light-emitting face 11b are to be formed at an interval in the light guide 11 in its extended direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
