Abstract: A light-emitting device according to an aspect of the present disclosure includes a light transmissive first electrode layer, a light transmissive second electrode layer, an electroluminescent layer between the first electrode layer and the second electrode layer, and a reflective layer located on a side opposite to the electroluminescent layer with respect to the second electrode layer. The reflective layer includes a base material having a refractive index equal to or higher than a refractive index of the electroluminescent layer, and fillers each having a refractive index different from that of the base material.

Abstract: An organic electroluminescence device comprise an organic electroluminescence element including a pair of electrodes and an organic layer disposed between the pair of electrodes and a sealing resin layer covering a surface of the organic electroluminescence element. The organic layer includes an emitting layer. The sealing resin layer includes a thermoplastic resin composite. The thermoplastic resin composite contains a matrix resin component constituted by at least one resin having a molecular weight of 5000 or more. A content of an organic component having a molecular weight of less than 500 in the thermoplastic resin composite is less than 6 ppm.
