1. A light-emitting device comprising:
- a first electrode layer having light transmissivity;
a second electrode layer opposed to the first electrode layer, the second electrode layer having light transmissivity;
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, whereinthe reflective layer includesa base material having a refractive index equal to or higher than a refractive index of the electroluminescent layer, andfillers each having a refractive index different from a refractive index of the base material.

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.
