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.

Abstract: According to an aspect of the present disclosure, a display apparatus includes a substrate in which a plurality of sub pixels is defined; a plurality of light emitting diodes which are disposed in the plurality of sub pixels, share a common organic layer and a cathode, and have an emission layer and an anode which are separated, respectively; a conductive layer disposed between the plurality of sub pixels; and a bank which is disposed below the cathode between the plurality of light emitting diodes and exposes the anode and the conductive layer. The plurality of sub pixels include a first sub pixel and a second sub pixel having a turn-on voltage lower than that of the first sub pixel, and the conductive layer is disposed to be closer to the second sub pixel between the first sub pixel and the second sub pixel.
