Claim:
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; a reflective layer located on a side opposite to the electroluminescent layer with respect to the second electrode layer; a low reflectance layer between the electroluminescent layer and the reflective layer, the low reflectance layer having a refractive index that is 95% or more and less than 100% of the refractive index of the electroluminescent layer; and a light extraction layer located on a side opposite to the electroluminescent layer with respect to the first electrode layer, wherein the reflective layer includes the base material includes a matrix and auxiliary filler particles.
