<P>PROBLEM TO BE SOLVED: To provide a guide light capable of securing luminance, without having to make the input power increase, while preparing a light-accumulating means. <P>SOLUTION: The guide light has a light guide plate 12, formed into a rectangular shape, and a display panel 11, where a guide sign formed by a light-transmitting material is inscribed. The light guide plate 12 is arranged to be in a shape where an incident face 12a, as one of peripheral faces, faces a light source 21 and an emitting face 12b as one face in the thickness direction faces the display panel 11. A light-accumulating layer 15 is formed on a light diffusion face 12c which is the back surface of the emitting face 12b of the light guide plate 12, by applying a light-accumulating material on the light diffusion face. <P>COPYRIGHT: (C)2010,JPO&INPIT |
