Claim:
1. A pixel circuit disposed in an active matrix display device, correspondingly to one of data lines and to one of scanning lines which are to be selected sequentially, the circuit comprising: an electro-optic element configured to be driven by an electric current; a drive transistor which is disposed in series with the electro-optic element and configured to control a drive current to be supplied to the electro-optic element; a drive capacitance element configured to hold a voltage for controlling the drive transistor; a first input transistor which has its control terminal connected to a corresponding one of the scanning lines, its first conduction terminal connected to a corresponding one of the data lines, and its second conduction terminal connected to one terminal of the drive capacitance element as well as to a control terminal of the drive transistor; and a second input transistor which has its control terminal connected to a scanning line preceding said corresponding scanning line, the scanning line preceding said corresponding scanning line being immediately before said corresponding scanning line in terms of selection sequence of the scanning lines in the active matrix display device and being a scanning line which corresponds to an adjacent pixel circuit, its first conduction terminal connected to said corresponding one of the data lines, and its second conduction terminal electrically and directly connected to said one terminal of the drive capacitance element as well as to the control terminal of the drive transistor.
