    • A display device includes: a pixel array including pixel circuits arranged in a matrix, each pixel circuit having a light emitting element, a drive transistor, and a storage capacitor storing a threshold voltage of the transistor and an inputted signal value; and a threshold correction operation means for performing a threshold correction operation plural times, which allows the storage capacitor to store the threshold voltage by applying a drive voltage to the transistor in a state where a gate potential of the transistor is fixed in a reference potential before giving the signal value to the storage capacitor. The threshold correction operation is started in a state where the gate potential is made a correction acceleration potential higher than the reference potential only at the threshold correction operation of the first half in the plural threshold correction operations, then, returns the gate potential to the reference potential to be fixed.
