Abstract: 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.

Abstract: A liquid crystal display device includes a display region (2) in which a plurality of liquid crystal display elements (10) are formed in a matrix and a peripheral region (3) enclosing the display region (2). The display region (2) includes gate lines (6) arranged in parallel with one another and reference voltage lines (9) each of which is formed between the gate lines (6) and serves as an electrode for a storage capacitor of each of the liquid crystal display elements (10). The peripheral region (3) includes connecting terminals (6) which are separated from each other by distance less than a distance between adjacent gate lines (6) in the display region (2). The connecting terminals (6) are arranged in groups. The gate lines (4) each connected to said connecting terminals (6). A short-circuit line (11) is formed along said peripheral region (3) so that the connecting terminals (6) are short-circuited. A conductor extending from the short-circuit line (11) is formed between a region (7) between the groups and the reference voltage lines (9) which face the region (7). This prevents dielectric breakdown for a storage capacitor of a liquid crystal display element connected to a predetermined gate line in a liquid crystal display device.
