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.

Abstract: A display device according to an example of the present disclosure includes a substrate in which an emission area and a non-emission area are divided and a plurality of sub-pixels are defined, an insulating layer disposed on the substrate, a first electrode disposed in each of the plurality of sub-pixels, a bank disposed on the insulating layer and exposing the first electrode through an opening thereof, an organic layer disposed on the first electrode, and a second electrode disposed on the organic layer. The bank includes exposed side surfaces by removing one area thereof between the plurality of sub-pixels, an undercut structure inwardly from lower ends of the exposed side surfaces. The bank further includes exposed side surfaces by removing an area thereof between the plurality of sub-pixels, and a trench structure by removing a portion of a thickness of the insulating layer.
