ABSTRACT:
The present invention relates to a configuration utilizing a driven element that is driven by a current. Specifically, there is provided a pixel circuit having a driven element and a current-drive transistor for supplying a current for driving the driven element to a current injection terminal of the driven element, a voltage buffer, a current signal line for supplying a current signal to the pixel circuit, and a wiring for connecting an output of the voltage buffer and a gate electrode of the current drive transistor. The pixel circuit has a switch for controlling connection between the voltage buffer and the gate electrode of the current-drive transistor, and an input terminal of the voltage buffer is connected to the current signal line.
