    Abstract: A unit pixel includes a circuit structure, first and second wiring patterns, an interlayer insulating layer, a planarization layer, and a light emission structure. The first wiring pattern disposed on the circuit structure has a first bump structure. The interlayer insulating layer covers the circuit structure and the first wiring pattern. The second wiring pattern disposed on the interlayer insulating layer overlaps the first wiring pattern and has a second bump structure. The planarization layer covers the interlayer insulating layer and the second wiring pattern and includes a via-hole exposing at least a portion of be second wiring pattern. The light emission structure contacts the second wiring pattern through the via-hole. The first and second wiring patterns and the interlayer insulating layer form a capacitor, the light emission structure includes an OLED, and the capacitor is directly connected to an anode of the OLED.

    Abstract: An organic light emitting display capable of improving display quality. The organic light emitting display includes a data driver for supplying bias power supply to data lines in a first period of one frame, for supplying reference power supply in a second period, and for supplying data signals in a fourth period, a scan driver for sequentially supplying scan signals to scan lines in the fourth period, pixels positioned at intersections of the scan lines and the data lines, and a first control line, a second control line, a third control line, and a fourth control line commonly coupled to the pixels. Each of the pixels includes a first capacitor for previously charging voltages corresponding to the data signals and a second capacitor charged by a voltage of the first capacitor in a third period between the second period and the fourth period.
