Abstract: Disclosed is an organic electroluminescence display device which can prevent the degradation of image quality and the property deterioration of a transistor provided in each pixel. The organic electroluminescence display device comprises data lines, gate lines, pixels and a power line, wherein, each of the pixels comprising: a first switching means having a first terminal, a second terminal, and a third terminal through which the data signal is outputted; a capacitor connected to the first switching means to be charged with the data signal; a second switching means for connecting the capacitor to the power line; a third switching means for connecting the capacitor to a ground terminal; a driving means having a first terminal, a second terminal, and a third terminal through which current from the power line is outputted; and an organic light emitting means connected to the driving means to emit light.
