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: Disclosed is an organic light emitting diode (OLED) display including a plurality of pixels, first and second scan signal stages, and emission control signal stages. The pixels are respectively arranged along n number of lines (n is a natural number), and each of the pixels include a first scan transistor, a driving transistor, a second scan transistor, and an emission control transistor. The first scan signal stages output first scan signals sequentially to the first scan transistors. The second scan signal stages output second scan signals sequentially to the second scan transistors. The emission control signal stages output emission control signals having a same phase to emission control transistors of two adjacent horizontal lines.
