Abstract:
A display device includes: a pixel array including pixel circuits arranged in a matrix state, in which each pixel circuit has a light emitting element, a drive transistor, and a storage capacitor storing a threshold voltage of the drive transistor and an inputted signal value; a threshold correction operation means for performing a threshold correction operation plural times, which allows the storage capacitor to store the threshold voltage of the drive transistor by supplying a drive voltage to the drive transistor in a state in which a gate potential of the drive transistor is in a reference value before giving the signal value to the storage capacitor; and a cut-off control means for cutting off the drive transistor by supplying an intermediate voltage which is lower than the drive voltage to the drive transistor in a after-correction period which is the period after the period of the threshold correction operation.
