Original Abstract Submitted
a display apparatus can include a bank insulating layer disposed on a substrate and defining an emission area in a pixel area; a planarization layer between the substrate and the bank insulating layer and including a planarization protruding portion overlapping with the emission area; an insulating pattern disposed on a side surface of the planarization protruding portion and spaced apart from an upper surface of the planarization protruding portion; and a light-emitting device disposed on the planarization layer in the emission area and having a stacked structure including a first electrode, a light-emitting layer and a second electrode. also, the side surface of the planarization protruding portion has a concave shape that is depressed toward an inside of the planarization protruding portion, and the insulating pattern is disposed between the first electrode and the light-emitting layer of the light-emitting device.
