PROBLEM TO BE SOLVED: To increase light-producing efficiency of an organic EL display element used for various displays. SOLUTION: This organic EL display element has such a structure in which on a transparent plate 11, a transparent electrode 12, light-emitting color material 13, metal electrode 14 and an insulation plate 15 are laminated in order, the transparent electrode 12 and the metal electrode 14 constitute an anode and a cathode respectively, and one side of the transparent plate 11 not contacting with the transparent electrode 12 has a shape of a convex lens. By using a convex lens, light-producing efficiency can be improved, and a bright display element can be obtained. |
