1. A self-luminous display device comprising:

  • pixel circuits; and

    a drive circuit, whereineach of the pixel circuits includesa light-emitting diode,a drive transistor connected to a drive current channel of the light-emitting diode, anda holding capacitor coupled to a control node of the drive transistor,the drive circuit applies a light emission enabling bias to the light-emitting diode after correcting the drive transistor and writing a data voltage to the control node,the drive circuit provides, during a light emission enabled period in which the light emission enabling bias is applied, a light emission interruption period adapted to change the light emission enabling bias to a non-light emission bias with the data voltage held by the holding capacitor, andthe drive circuit performs a light emission disabling process, adapted to reverse-bias the light-emitting diode to stop the light emission, for a constant period after the light emission enabled period.
