<P>PROBLEM TO BE SOLVED: To provide a surface emitting device which effectively prevents collapsing of balance of luminance and can provide a superior appearance. <P>SOLUTION: The surface emitting device 10 is approximately constructed of a light source 11, a light guide 13 of sheet shape which is arranged in proximity to an outgoing face 11a of the light source 11 and is rectangular in a plan view, and a sheet switch 20 which is arranged on one face 13a side of the light guide 13, and an adhesive material 15 includes a reflecting layer having a mirror effect. This adhesive material 15 is made into a so-called double-sided tape shape in which an adhesive material layer coated with an adhesive material is formed, for example, on both sides of a sheet-like substrate, and a reflecting layer is provided on the substrate or on the adhesive material layer. Thereby, it is prevented that excessive light emission is performed penetrating the adhesive material 15 and uniformity of luminous distribution when lighted from the light source 11 is achieved. <P>COPYRIGHT: (C)2010,JPO&INPIT |
