Provided is an OLED display device including a circuit that controls a voltage of an Nth row unit pixel and a voltage of anodes of pixel lines adjacent to the Nth row unit pixel in order to minimize a voltage difference between the Nth row unit pixel and the pixel lines adjacent to the Nth row unit pixel to suppress a decrease in luminance of the Nth row unit pixel caused by a leakage current introduced to the Nth row unit pixel. The circuit is configured to set the voltage of the anodes of pixel lines adjacent to the Nth row unit pixel to be equal to or lower than a voltage of an anode of the Nth row unit pixel when the Nth row unit pixel is in a sampling period or a programming period during a driving timing of an OLED display device.. Accordingly, it is possible to minimize flow of an unintended leakage current toward a low-potential anode via a common single layer caused by a voltage difference in anode between a pixel including a high-potential anode and a pixel including the low-potential anode.
