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: A display device in one embodiment includes a flexible substrate, a back plate disposed under the flexible substrate to support it, a conductive layer disposed on at least one surface of the back plate, and a printed circuit board connected to one side of the flexible substrate. The conductive layer is electrically connected to the printed circuit board and receives a constant voltage applied thereto. Therefore, by applying the constant voltage to the conductive layer, it is possible to reduce the polarization occurring on the flexible substrate.
