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.
