ACTIVE MATRIX DISPLAY DEVICE

摘要

PURPOSE:To provide an active matrix display device capable of reducing OFF currents. CONSTITUTION:In this active matrix display device, the discharging amount of an auxiliary capacitance 114 at the time of OFFs of thin film transistors is reduced by providing plural thin film transistors 111, 112 which connecting them in series with respect to one pixel electrode and making at least one thin film transistor be always in an ON-state except both ends of thin film transistors 111, 112 connected in series or by connecting at least one capacitance 113 between the connection point of the drain and the source of series-connected thin film transistors 111, 112 and an AC. grounded point.
