PROBLEM TO BE SOLVED: To suppress generation and growth of dark spots and to prevent short circuit between both electrodes in an electroluminescent element having an organic EL layer. SOLUTION: An anode electrode 2, an organic EL layer 3, a cathode electrode 4, an inorganic protection film 5, a silane-coupling layer 6, and an organic protection film 7 are formed on the upper surface of a transparent substrate 1. The surface of the organic protection film 7 and the upper surface of the transparent substrate 1 are covered with a resin sealing film 12, formed previously on the lower surface of a facing substrate 11. Since the anode electrode 2, the organic EL film 3, and the cathode electrode 4 are covered with the inorganic protection film 5 and the resin-sealing film 12, infiltration of oxygen and water from the outside can be prevented. Also the generation and growth of dark spots can be suppressed. Residual stress produced at curing of the resin-sealing film 12 can be released with the organic protection film 7, so that short circuit between both electrodes is prevented. |
