Summary: | A pixel circuit provided on a substrate on which a signal line, first and second scanning lines supplying first and second control pulse signals, a fixed power line, and a variable power line are arranged includes a capacitance element, a sampling transistor connected between the signal line and one of ends of the capacitance element, where the gate of the sampling transistor is connected to the first scanning line, a drive transistor of which gate is connected to the other end, where one of a drain and a source of the drive transistor is connected to the fixed power line, an initializing transistor of which gate is connected to the second scanning line, which is connected between the other end and the other of the drain and the source, and a light emitting element connected between the variable power line and the other of the drain and the source. |
