Abstract
A pixel circuit includes: a light emitting element; an n-channel drive transistor Tthat has a source connected with an anode of the light emitting element, a gate connected with a pixel node, and controls a light emission current flowing in the light emitting element in accordance with a light emission control voltage between the gate and the source; a transfer transistor Twhich is interposed between a data signal line and the pixel node, and has a gate connected with a scan signal line; a control transistor Twhich is interposed between the source and a drain of the drive transistor T, has a gate connected with the scan signal line, and comes into an ON state simultaneously with the transfer transistor T; and a capacitance element which is interposed between the gate and the source of the drive transistor T, and holds the light emission control voltage.
