DISPLAY APPARATUS AND ELECTRONIC DEVICE

Provided are a display apparatus and an electronic device having excellent color purity. A display apparatus includes a plurality of first electrodes disposed two-dimensionally, a second electrode disposed on a side of a first surface of each of the first electrodes, an electroluminescence layer disposed between the first electrodes and the second electrode, a reflector facing a second surface of each of the first electrodes, an interlayer film covering the reflector, and an insulating layer provided between adjacent first electrodes of the plurality of first electrodes and having a plurality of openings, in which each of the openings is provided on the first surface of each of the first electrodes, and the reflector, the interlayer film, the first electrodes, the electroluminescence layer, and the second electrode constitute a resonator structure that resonates emitted light from the electroluminescence layer, and in a case where a region corresponding to each of the openings is a first region and a region corresponding to an outer side of the first region in a region corresponding to each of the first electrodes is a second region in a plan view, a resonance order of a portion corresponding to the first region and a resonance order of a portion corresponding to the second region are different in the resonator structure.
