Abstract:
1. A display device on which a plurality of pixels including self-luminous elements is two-dimensionally arranged, the display device comprising: each of a plurality of pixel circuits which is provided to each of the pixels and configured to supply a self-luminous element with a current or a voltage; a plurality of power supply lines configured to supply the pixel circuits with power; a plurality of data lines configured to supply the pixel circuits with gradation data; a plurality of control signal lines configured to supply the pixel circuits with control signals; and a peripheral circuit configured to control the plurality of data lines and the plurality of control signal lines, said each of the pixel circuits including: a driving transistor, having a gate electrode, a drain electrode and a source electrode, configured to supply the self-luminous element with the current or the voltage; a storage capacitor provided between the gate electrode of the driving transistor and one of the control signal lines; a first switch transistor configured to connect the gate electrode of the driving transistor with the drain electrode thereof; and a second switch transistor for controlling supply of current or voltage to the self-luminous element, wherein a gate electrode of the first switch transistor is connected directly or via a third switch transistor to the data line and is supplied from the data line with a binary signal to turn on and off the first switch transistor, and the peripheral circuit controls a time period of a voltage level of the binary signal which turns on the first switch transistor according to the gradation data.
