Claim Text:
1. An active matrix display device, comprising: a display section including a plurality of data lines, a plurality of scanning lines, a plurality of emission control lines along the respective scanning lines, and a plurality of pixel circuits disposed correspondingly to the data lines, the scanning lines and the emission control lines; a scanning driving section configured to sequentially select the scanning lines; and an emission control driving section configured to drive the emission control lines; wherein the pixel circuit includes: an electro-optic element driven by an electric current; a first input transistor having its control terminal connected to a corresponding one of the scanning lines, and configured to turns ON when said scanning line is selected; a drive transistor provided in series with the electro-optic element, and configured to control a drive current that is to be supplied to the electro-optic element, in accordance with a data voltage supplied via a corresponding one of the data lines and the first input transistor; and an emission control transistor having its control terminal connected to a corresponding one of the emission control lines, and provided in series with the electro-optic element; and wherein the emission control driving section includes: OFF-control switching elements each provided correspondingly to one of the emission control lines and configured to change an electric potential of said emission control line to an OFF level to turn OFF the emission control transistor in accordance with a state of one of the scanning lines which precede the scanning line that is along said corresponding emission control line or a state of the scanning line that is along said corresponding emission control line; and ON-control switching elements each provided correspondingly to one of the emission control lines and configured to change the electric potential of the emission control line to an ON level to turn ON the emission control transistor in accordance with a state of one of the scanning lines which follow the scanning line that is along said corresponding emission control line.
