Abstract
A display apparatus and a method of manufacturing a display apparatus, the display apparatus including a first area, the first area including a structure of thin layers on a substrate; a second area, the second area including a structure of thin layers on the substrate; a planarization layer that planarizes the first area and the second area; and a step-height compensation layer, wherein the structure of thin layers of the first area is different from the structure of thin layers of the second area, the step-height compensation layer compensates for a height difference between the first area and the second area due to the different structures of thin layers, and the step-height compensation layer is between the substrate and the planarization layer and in the first area or the second area.
