    摘要: An active matrix type liquid crystal display device with a short-circuiting wire for mutually short-circuiting address wires and data wires through the medium of resistors made of a thin-film transistor is formed along the periphery of a display region on an insulating substrate. The short-circuiting wire is electrically connected inside a region in which the resistors made of a thin-film transistor are formed. In one embodiment, the transistors are surrounded by a portion of the shod circuiting wire. In another embodiment, they are partially surrounded by the wire with a gate electrode which is not protruding out. In another embodiment they are formed with two source and drain regions, one which has a lower breakdown voltage than the other.
