摘要： A display device including pixel circuits arranged in a form of a matrix, with the pixel circuits respectively including an electro-optical element, a drive transistor, a sampling transistor, and a capacitive element. The sampling transistor samples a signal from the signal line in the capacitive element. The drive transistor and the electro-optical element are arranged in series to form a current path between a power supply line and a ground line. The drive transistor is configured to control a driving current through the current path according to a signal potential stored in the capacitive element. Compensation for driving current dependence on a characteristic of the drive transistor is provided, with such compensation being based upon a current through the current path occurring before a light emission period.
