Abstract: A display apparatus includes a substrate on which a plurality of sub-pixels is defined, a plurality of anodes disposed in each of the plurality of sub-pixels on the substrate, an organic layer disposed on the plurality of anodes, a cathode disposed on the organic layer, and a bank disposed between the anode and the organic layer and between emission areas of each of the plurality of sub-pixels. The bank includes a plurality of trenches, and the organic layer and the cathode are disposed in the bank and the plurality of trenches. As a result, a resistance of the organic layer in which a leakage current flows from the trench increases, so that the leakage current which may be transmitted to the adjacent sub-pixels and color mixing due to the leakage current can be minimized.
