Abstract: PURPOSE: A pixel and an organic electroluminescence display apparatus including the same are provided to display the image with uniform picture quality regardless of the schedule variance of a capacitor, which is included in a pixel, by uniformly keeping the capacitance ratio of a boosting capacitor and a storage capacitor. CONSTITUTION: An organic light emitting diode is connected between a first power source(ELVDD) and a second power source. A pixel circuit controls a driving current, which is provided to the organic light emitting diode, by being connected between the first power source and the organic light emitting diode. The pixel circuit includes a first transistor in which a first electrode is connected to a data line, a second electrode is connected to a first node, and a gate electrode(20) is connected to a present scanning line(S1, Sn-1). The first electrode is connected to the first power source via the first node, the second electrode is connected to an organic light emitting diode, and the gate electrode is connected to a second node in a second transistor(T2). A first capacitor(C1) is connected between the first power source and the second node. A second capacitor(C2) is connected between the second node and the present scanning line. An opening part(40) is formed in one or more of two electrodes of the first capacitor in an area in which two electrodes of the first capacitor are overlapped each other.

Abstract: An organic light emitting display device comprising: a data driver supplying data signals to data output lines; a scan driver supplying scan signals sequentially to scan output lines; a light emitting control line driver supplying light emitting control signals to light emitting control output lines; and a pixel unit including a plurality of pixels connected to the output lines of each driver, at least one driver having a buffer circuit disposed at each output line. Each buffer circuit comprises a transistor having a gate layer, source and drain layers and a metal layer for shielding Electro-Static Discharge (ESD), wherein the metal layer is formed over the gate layer when the gate layer is overlapped by one of the source or a drain electrodes, or the metal layer is formed to not overlap the gate layer when the gate layer is not overlapped by the source or a drain electrodes.
