Display device and electronic device

Abstract

Provided is a display device capable of suppressing fluctuation in light emission luminance. A display device includes: a first electrode layer having a plurality of electrodes arranged two-dimensionally; a second electrode layer provided to face the first electrode layer; an electroluminescence layer provided between the first electrode layer and the second electrode layer; and an insulating layer provided between adjacent electrodes. The insulating layer has a plurality of openings, and each of the plurality of openings is provided corresponding to each of the electrodes. The insulating layer includes a plurality of localized portions, and each of the plurality of localized portions is localized around each of the openings. The insulating layer forms a potential barrier between the electroluminescence layer and the localized portion.
