PROBLEM TO BE SOLVED: To provide a light spot type display device, in which bright and high- quality display can be obtained and the cloudiness phenomenon of a display body will not be generated, even at a non-lighting time and whose cost is low and which is made to cope with energy saving. SOLUTION: In a light spot type display device, 1 in which a light source 4 is provided at one side face of a light transmission plate 2 which has translucency and which is constituted by forming a plurality of reflection dots, consisting of minute recessed parts and a reflection dot group 6 is displayed, by making rays of light from the light source 4 to be reflected on the reflection dot group 6, after the light transmission plate is formed by changing the arrangement density of reflection dots at flat plate parts and a part which is turned into a curved surface, while anticipating the amount of change in which the opening diameter of the reflection dots formed in the flat board shaped light transmission plate is changed by the curvature of the plate, and the curved surface is formed by bending the plate. |
