Abstract:
A driving method of a display device having a driving transistor and a display element, one source/drain region of the driving transistor connected to a power supply part, the other source/drain region connected to an anode electrode provided in the display element, the method includes the steps of: setting a potential of the anode electrode by applying a predetermined intermediate voltage to the anode electrode so that a potential difference between the anode electrode of the display element and a cathode electrode at the other end of the display element does not exceed a threshold voltage of the display element; and then holding the driving transistor in OFF-state while a drive voltage is applied from the power supply part to one source/drain region of the driving transistor.
