Abstract
A display device includes a plurality of pixels and a compensation power supply line. The pixels are located at intersections of data lines and gate lines. The compensation power supply line is separated from the data lines. Each of the pixels includes an in-pixel circuit and at least one out-pixel circuit. The in-pixel circuit includes a first transistor, to be controlled based on a data voltage from a corresponding one of the data lines, and a storage capacitor connecting the first transistor and a first node. The at least one out-pixel circuit receives a compensation voltage from the compensation power supply line and provides the compensation voltage to the first node.
