Display devices and electronic devices

Abstract

The present invention provides an electronic apparatus and a display device having excellent color purity.　This display device comprises: a plurality of first electrodes disposed in two dimensions; a second electrode disposed on a first surface side of the first electrodes; an electroluminescence layer disposed between the first electrodes and the second electrode; a reflective plate that faces a second surface of the first electrodes; an interlayer film that covers the reflective plate; and an insulating layer that is provided between the first electrodes that are adjacent and has a plurality of openings. The openings are respectively provided in the first surface of the respective first electrodes. The reflective plate, the interlayer film, the first electrodes, the electroluminescence layer, and the second electrode form a resonator structure that resonates light emitted from the electroluminescence layer. When, in a plan view, a first region is a region corresponding to the openings and a second region is a region, from among a region corresponding to the first electrodes, that corresponds to the outside of the first region, the resonator structure is such that the resonance order of a portion corresponding to the first region is different from the resonance order of a portion corresponding to the second region.
