摘要:
A display device including pixels, in which each of the pixels includes: a positive power supply line and a negative power supply line; a drive transistor that drives a current in a current path according to a gate-source voltage; an organic EL element including an anode and a cathode that are disposed in the current path; an electrostatic storage capacitor that stores the gate-source voltage by having a first electrode connected to a gate of the drive transistor, and a second electrode connected to a source of the drive transistor; a switch transistor that switches a conduction state between the second electrode and a data line; and a switch transistor for applying a negative power supply line voltage to the first electrode. A potential difference between a first power supply line voltage VDDp and a second power line voltage VEEp decreases with proximity to the center of a display unit.
