Abstract: A display device includes a substrate having an insulating surface; a plurality of pixel electrodes on the insulating surface, the plurality of pixel electrodes located away from each other; a first insulating layer covering an end of each of the pixel electrodes and exposing a part of a top surface of each of the pixel electrodes; and an organic layer provided on each of the pixel electrodes, the organic layer including a light emitting layer. As seen in a plan view, the first insulating layer includes a plurality of first regions, each of the plurality of first regions being around the exposed part of the top surface of the pixel electrodes, and a second region located between two adjacent first regions, the second region including a recessed portion.
