項(1)記載の表示装置。[Scope of Claim for Utility Model Registration] (1) The display board excludes a transparent colored layer, a light-diffusing layer, and a transparent display portion such as characters, which are arranged in a laminated or overlapping manner from the outer surface side. In an internally illuminated display device comprising a light shielding layer and a light source disposed inside the display plate, the light diffusing layer has a transparent synthetic resin as a matrix and transmits light into the matrix. A display device characterized in that transparent particles having a refractive index different from that of the transparent synthetic resin are uniformly dispersed. (2) The display device according to claim (1), wherein the transparent particles have a different optical refractive index from the matrix resin in a range of 0.01 to 0.2.
