1. A light-emitting device comprising:
a substrate;
an electrode having reflectivity and transparency;
a first pixel electrode that has reflectivity and that is provided between the substrate and the electrode;
a second pixel electrode that has reflectivity and that is provided between the substrate and the electrode;
a light-emission functional layer provided between the electrode and the first pixel electrode and between the electrode and the second pixel electrode;
an insulating layer provided between the light-emission functional layer and the first pixel electrode and between the light-emission functional layer and the second pixel electrode;
a first optical path adjustment layer being disposed between the first pixel electrode and the electrode; and
a second optical path adjustment layer being disposed between the second pixel electrode and the electrode, a thickness of the second optical path adjustment layer being thicker than a thickness of the first optical path adjustment layer, wherein
a first distance between a top surface of the first pixel electrode and a bottom surface of the electrode is different from a second distance between a top surface of the second pixel electrode and the bottom surface of the electrode, and
a thickness of the insulating layer is less than a difference between the first distance and the second distance.
