PROBLEM TO BE SOLVED: To realize a device having a small circumferential nonluminescent part and a narrow edge by mounting a power supply band along one side of a transparent electrode, folding ends of the transparent electrode and a fluorescent layer from a front side to a back side, and mounting the power supply band at the back side so that it is extended along the extending direction of a folding line. SOLUTION: The light from a fluorescent layer 3 penetrates through a transparent electrode 2, and a surface at the transparent electrode 2 side totally generates the light. As the transparent electrode 2 has a comparatively high resistance, the loss of voltage increases and brightness decreases at the part farther separated from a center of contact point, when the transparent electrode 2 is connected to an input terminal 4 on a pin point similarly as a back electrode 1. To reduce the unevenness of the brightness, a power supply band 5 formed by coating the silver paste into the band shape, is placed along a side of the transparent electrode 2, and the input terminal 4 is connected to the power supply band 5. As the input terminal can be contacted with the transparent electrode 2 with a wider area by the power supply band 5, the evenness of brightness can be improved. A part of the power supply band 5 is folded to a back surface (back electrode 1 side), and the whole is sealed by a package film 6 to from a sealing part 7.
