Abstract
In a display apparatus that includes an active matrix substrate on which multiple pixel circuits are disposed, each having a light emitting element, a drive transistor, a capacitor element connected between a gate terminal and the source terminal of the drive transistor, and a selection transistor, and a threshold voltage of the drive transistor is corrected by causing the capacitor element to hold the threshold voltage of the drive transistor, reverse bias voltages, each having a magnitude corresponding to a preset initial threshold voltage and a drive voltage of the drive transistor, the magnitude of the drive voltage being dependent on the amount of emission of the light emitting element, are supplied to the gate terminal of the drive transistor.
