Abstract:
1. A current-driven type display device comprising: a plurality of pixel circuits arranged at respective intersections of a plurality of scanning lines and a plurality of data lines; and a drive circuit that selects a write-target pixel circuit using the corresponding scanning line, and provides a data potential according to display data to the corresponding data line, wherein each of the pixel circuits includes, a second electrode of the compensation capacitor is connected to a control wiring line to which the drive circuit provides a potential, for the write-target pixel circuit, the drive circuit is configured to provide a potential according to the display data and a threshold voltage to the control terminal of the drive element by controlling the writing switching element and the compensation switching element to a conducting state and controlling the interruption switching element to a non-conducting state while providing the data potential to the data line, and thereafter switch a potential provided to the second electrode of the compensation capacitor to another by switching a potential provided to the control wiring line to another with states of the respective switching elements including the compensation switching element being maintained, to provide a write potential according to the display data and the threshold voltage to the control terminal of the drive element, and after the drive circuit switches the potential provided to the control wiring line to another to provide the write potential to the control terminal of the drive element, the drive circuit switches the potential provided to the data line to a reference potential which is closer to the potential at the control terminal of the drive element than the data potential.
