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.

Method of making a display apparatus using a selective mask structure

A method for manufacturing a display panel includes forming a circuit element layer including a transistor on a plurality of cell areas of a first working substrate. Each of the cell areas includes a hole area on which at least one first sub-opening groove on which the circuit element layer is not formed is located. The method further includes forming a display element layer including a light emitting element on the plurality of cell areas, removing at least one inorganic layer of the display element layer formed in the first sub-opening groove by stamping to define a second sub-opening groove, coupling the first working substrate to a second working substrate to define a working panel, and cutting the working panel into portions corresponding to the plurality of cell areas.
