Abstract: A display panel which includes a base layer, a pixel defining layer on the base layer and that has a light emitting opening, a barrier wall on the pixel defining layer and that has a barrier wall opening that overlaps the light emitting opening, and a light emitting element including an anode, an intermediate layer, and a cathode that makes contact with the barrier wall. The barrier wall opening includes a first inner surface and a third inner surface that extend in a direction parallel to a first direction, a second inner surface and a fourth inner surface that extend in a direction parallel to a second direction crossing the first direction, a first corner region, a second corner region, a third corner region, and a fourth corner region.

Abstract: A display apparatus includes: a substrate that includes a display area, an opening area formed in the display area, and a non-display area that surrounds at least a portion of the opening area; a pixel defining area formed on the substrate and that includes at least one opening; an intermediate layer disposed on the at least one opening; an opposite electrode that covers the intermediate layer and the pixel defining layer; and a capping layer that covers the opposite electrode. An end portion of at least one of the intermediate layer, the opposite electrode, or the capping layer is formed on the pixel defining layer and has a thickness that decreases away from the at least one opening.
