Abstract
Pixel circuits each include a write transistor having a gate electrode connected to a write control line, one of a drain electrode and a source electrode connected to a data line for transmitting data voltage corresponding to luminance of the pixel circuit, and the other of the drain electrode and the source electrode connected to a gate electrode of a drive transistor. A compensation circuit includes a compensation transistor connected to a compensation signal line and the write control line. A compensation voltage generation circuit outputs compensation control voltage in accordance with a representative value of data voltage for the pixel circuits. A capacitance of the write control line caused by the compensation transistor and a capacitance of the write control line caused by the write transistors of the pixel circuits have mutually opposite voltage dependence with respect to the representative value of the data voltage for the pixel circuits.
