Abstract
A driving circuit integrated type active-matrix liquid crystal display device is arranged such that a buffer composed of a P-channel thin film transistor and an N-channel thin film transistor that are connected in series is adopted for the P-channel thin film transistor and an N-channel thin film transistor; at least one of the P-channel thin film transistor and the N-channel thin film transistor is composed of a plurality of thin film transistors that are connected in parallel; and at least one of a power source line and an output line connected to the plurality of thin film transistors connected in parallel is formed in a wiring pattern composed of a main wiring section and a branched wiring section branched into respective thin film transistors. The described arrangement permits a line-shaped defect due to a defective thin film transistor which constitutes a buffer of the drive circuit to be eliminated with ease, while improving a yield of panels.
