Electroluminescent element

Abstract

The present invention provides an electroluminescent element, comprising: a substrate; a first electrode layer formed on a surface of the substrate; an organic electroluminescent layer formed on the first electrode layer, the organic electroluminescent layer including at least a luminescent layer; a second electrode layer formed such that the organic electroluminescent layer is interposed between the first electrode layer and the second electrode layer; and a sealing base material for sealing the first electrode layer, the organic electroluminescent layer and the second electrode layer, wherein the sealing base material is a flexible film and a lamination impact alleviating layer of which universal hardness value is no smaller than 110 N/mm2 is formed on the second electrode layer. According to the present invention, when a flexible film is used as the sealing base material and the flexible film is laminated with the substrate at a predetermined pressure, the organic electroluminescent layer is prevented from being scratched or cracked. Thus, an EL element which effects even luminescence can reliably be obtained.
