ABSTRACT:
A logic circuit performs a logic operation on a plurality of input logic signals and outputting a resultant logic signal. The logic circuit comprises a pass-transistor logic circuit including: a plurality of field effect transistors, at least two of the plurality of field effect transistors being coupled in series, a gate electrode of each of the at least two field effect transistors receiving a corresponding first logic signal, and one of drain and source electrodes ditto receiving a corresponding second logic signal; and a node for coupling the other of the drain and source electrodes of the at least two field effect transistors, and for outputting the resultant logic signal. The plurality of field effect transistors are thin film transistors (TFTs).
