<P>PROBLEM TO BE SOLVED: To provide a light guide plate capable of securing a necessary luminance even in the case viewed from an oblique direction, and to provide a display device provided with such the light guide plate. <P>SOLUTION: The light guide plate 9 is provided with: a light guide portion 92 having an incident face 92a into which light from a light source 61 enters; a light emitting portion 91 which is connected to the light guide portion 92 and is arranged overlapped with a dial; and a reflecting portion prepared on a rear face 91b of the light emitting portion 91, which reflects the light introduced by the light guide plate 92 to the light emitting portion 91 toward the front face 91a opposed to the dial in the light emitting portion 91. Then, the light guide plate 9 has a diffusion reflection portion 97 which diffuses light passing an optical path along the plane direction of the light emitting portion 91 in the vicinity of the inner edge 91e of the front face 91a of the light emitting portion 91 which is a part of the optical path from the incident face 92a to the reflecting portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
