Abstract

A light-emitting device includes a semi-transmissive reflection layer, a first reflection layer that is disposed in a first sub-pixel, a first pixel electrode that is disposed in the first sub-pixel, a first color filer that is disposed in the first sub-pixel, a second reflection layer that is disposed in a second sub-pixel, a second pixel electrode that is disposed in the second sub-pixel, a second color filter that is disposed in the second sub-pixel, the second color filter that is same color as the first color filter, a light-emitting functional layer, and an insulating layer that is disposed between the first reflection layer and the first pixel electrode, the light-emitting functional layer that is disposed between the second reflection layer and the second pixel electrode. A thickness of the insulating layer in the second sub-pixel is thicker than a thickness of the insulating layer in the first sub-pixel.
