Abstract
In a display device, a signal line drive circuit applies an initialization voltage to control terminals of drive transistors from corresponding video signal lines, and applies a reset potential to first terminals of the drive transistors from corresponding reset lines to initialize the drive transistor, and the initialization voltage is set to a lower value as a voltage value of the gradation voltage signal written after offset cancellation for offset-canceling a threshold value of the drive transistor is higher.
