<P>PROBLEM TO BE SOLVED: To provide a display device capable of emitting bright light with high uniformity. <P>SOLUTION: A light guide body 11 guides light emitted from a light source 20. An optical diffusion section 13 is formed on the light guide body 11 and diffuses the light guided by the light guide body 11. A design display section 12 is formed on the light guide body 11 and displays a design. A low-refractive-index section 14 is formed between the light guide body 11 and the design display section 12, and has the light refractive-index lower than that of the light guide body 11. The optical diffusion section 13 is formed of two or more printed layers and on a rear face 112 of the light guide body 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
