Abstract:
1. A pixel circuit comprising: an electro-optical element changing a luminance changes based on a flowing current, a signal line supplied with a data signal corresponding to at least a luminance information; a first control line; a drive transistor forming a current supply line between a first terminal and a second terminal and controlling a current, flowing into the current supply line, based on a potential of a control terminal; a node electrically couplable to the control terminal of the drive transistor; and a first switch connected between the signal line and the node and controlled with a conductive state and a non-conducive state by the first control line, wherein during a frame, the pixel circuit is able to set a correction period for correcting a variation of property of the drive transistor in a pixel, a write period for driving the first switch by the first control line and writing the data signal from the signal line to the node, and a drive period for storing the written data signal and driving the electro-optical element, and the pixel circuit is driven and controlled so that an interval having the correction period, the write period, and the drive period are carried out, and an interval having the write period and the drive period without the correction period exist.
