Abstract:
1. A display device, comprising: luminescence pixels arranged in a matrix; data lines for determining a luminescence of the luminescence pixels; write control lines for controlling writing of a signal voltage to the luminescence pixels; and bias control lines for controlling an application of a predetermined bias voltage to the luminescence pixels, wherein each of the luminescence pixels includes: the display device further comprises: the controller is configured to cause the non-conduction state between the data line and the data driving circuit, cause the conduction state between the data line and the bias supplying circuit, and apply the predetermined bias voltage to the one of the anode and the cathode of the luminescence element within a period in which the signal current does not flow to the luminescence element, and the predetermined bias voltage being applied to the one of the anode and the cathode of the luminescence element within the period in which the signal current does not flow to the luminescent element as a result of turning OFF the first transistor.
