Abstract: A display apparatus includes: a substrate including a first area, a second area, and a third area that is between the first area and the second area; a plurality of first to third display elements respectively arranged in the first to third areas, each of the plurality of first to third display elements including a pixel electrode; and an insulating layer including a plurality of first to third openings that respectively expose at least portions of the pixel electrodes of the plurality of first to third display elements. A number of the plurality of first openings is greater than a number of the plurality of second openings per unit area. In a plan view, an area of the plurality of first openings is greater than an area of the plurality of third openings.
