Abstract
A display apparatus includes a substrate, a display area disposed on the substrate and including a plurality of pixels, a first planarization layer disposed on the substrate, a second planarization layer disposed on the first planarization layer, a pixel-defining layer disposed on the second planarization layer and covering at least one edge of a first electrode of each of the plurality of pixels, a plurality of first holes disposed between the plurality of pixels and spaced apart from the first electrode, and a first etching prevention layer disposed on a bottom surface of each of the first holes and on the first planarization layer. Each of the first holes includes an opening that passes through the second planarization layer and the pixel-defining layer.
