Patent ID: 6924875

Claim:
An array substrate comprising: a substrate; a plurality of scanning lines formed on the substrate; a plurality of signal lines formed on the substrate so as to intersect the scanning lines, each signal line having one end and the other end; thin film transistors provided at intersections of the scanning lines and the signal lines, a gate of each thin film transistor being connected to the corresponding scanning line, and a source thereof being connected to the corresponding signal line; pixel electrodes each corresponding to one of the thin film transistors, and each being connected to a drain of the corresponding thin film transistor; an input/output terminal group provided at an edge portion of the substrate, including input/output terminals used for inputting signals from the outside and outputting signals to the outside; a scanning line driving circuit for driving the scanning lines; a signal line driving circuit, connected to the one end of each signal line, for driving the signal lines; a first wiring line formed on the substrate, connected to at least one of the input/output terminals in the input/output terminal group; and diodes each connecting the other end of each of the signal lines to the first wiring lines, wherein the first wiring line includes a second wiring line and a third wiring line connected to the different input/output terminals, and a first diode and a second diode are provided to the other end of each signal line, an anode of the first diode being connected to the other end of the signal line, a cathode thereof being connected to the second wiring line, an anode of the second diode being connected to the third wiring line, and a cathode thereof being connected to the other end of the signal line.
