Each pixel in a display device includes an emissive element, a driver
transistor, a control transistor, and a control capacitor. The driver
transistor is provided between the emissive element and a power supply
and controls supply of power from the power supply to the emissive
element. The control transistor is connected between a constant voltage
power supply and a gate of the driver transistor, receives a digital data
signal on a gate, and controls whether or not to fix a gate voltage of
the driver transistor. The control capacitor is connected between a
control line and the gate of the driver transistor. The gate voltage of
the driver transistor is shifted to a voltage corresponding to a control
pulse signal when the control transistor is off and is non-fixed during a
light emission period defined by the control pulse signal applied to the
control line.
