Abstract
Display devices that prevent the generation of a step between subpixels are disclosed. In one example, a display device includes a substrate and subpixels of a plurality of colors two-dimensionally arranged on the substrate. Each of the subpixels includes a light-emitting element with a resonator structure, and the light-emitting element includes a reflective layer, an optical path length adjustment layer, a first electrode, an electroluminescent layer, and a second electrode in this order. The optical path length adjustment layer has a facing surface facing the electroluminescent layer, and the height of the facing surface is constant for each of the subpixels of the plurality of colors. The optical path length adjustment layer includes a plurality of refractive index layers with different refractive indexes, and the optical path length adjustment layer has a different layer configuration for each of the subpixels of the plurality of colors.
