Abstract:
A pixel circuit includes a pixel electrode, a pixel transistor of a first conduction type, and a flip-flop. The pixel transistor has a control node connected to a scanning line, a first node connected to a data line, and a second node. The flip-flop has an inverter and a feedback transistor of a second conduction type opposite to the first conduction type. The inverter has an input node connected to the second node of the pixel transistor, and an output node connected to the pixel electrode. The feedback transistor is controlled to be turned on or off in accordance with an output of the inverter for supplying a high-level power source voltage or a low-level power source voltage to a common connection point of the second node of the pixel transistor and the input node of the inverter, in the ON state.
