Abstract
A display apparatus includes a substrate including an emission area and a non-emission area surrounding the emission area, a planarization layer formed on the substrate, a light emitting device disposed on the planarization layer, and including an anode electrode, and a separation layer disposed to be spaced apart from the anode electrode on the planarization layer, wherein the planarization layer is formed to overlap at least a portion of the non-emission area and includes a trench portion formed by removing at least a portion of the planarization layer, the trench portion at least partially overlaps an end of each of the anode electrode and the separation layer in the non-emission area, the light emitting device further including a light emitting layer and a cathode electrode sequentially formed on the anode electrode, and the light emitting layer and the cathode electrode are discontinuously formed in the trench portion.
