PROBLEM TO BE SOLVED: To obtain a light storage type display which may be reduced in the size, weight, etc., of a device, is simple in management and is capable of emitting light at night without using a commercial power source by forming a light storage layer which is a mixture composed of light storage material particles to emit light with UV on a light reflection layer and a transparent vehicle, an adherable transparent layer and a light transparent image layer of a light transparent image layer image body. SOLUTION: The light storage layer 2 which is the mixture prepd. by mixing the light storage material particles to emit light with the UV and polyvinyl chloride, polyester resin, acryl ester resin, etc., which are transparent vehicle or forming the mixture into a paste form is formed on the rear side of the adherable transparent layer 1. Next, the light transparent image layer 4 is directly formed on the front side of the adherable transparent layer 1 and the light reflection layer 3 of white or silver is formed on the light storage layer 2 side. At this time, the transparent layer 1 and the adhesive layer are preferably formed between the light storage layer 2 and the light transparent image layer 4 at the time of forming the light transparent image layer 4 adherable to the light storage layer 2 when the light storage material content is >=7 to <=60%.
