Abstract:
A liquid crystal display device provided with a driving circuit deposited on a substrate having formed thereon a plurality of display pixel sections, said driving circuit being provided for driving the display pixel sections, wherein:said driving circuit includes a buffer composed of a P-channel thin film transistor and an N-channel thin film transistor that are connected in series,at least one of said P-channel thin film transistor and said N-channel thin film transistor is composed of a plurality of thin film transistors that are connected in parallel between a power source line and an output line, andat least one of said power source line and said output line is formed in a wiring pattern composed of a main wiring section and branched wiring sections branched into respective thin film transistors, so that when any of said plurality of thin film transistors connected in parallel becomes defective, a thin film transistor which has become defective is alone disconnectable from one of said power source line and said output line.
