摘要 To prevent an electrostatic damage on a display device formed with a driving circuit. Protective circuits are provided not only at input terminal parts, but also at intermediate parts of a circuit or at the ends of wiring lines. Otherwise, the protective circuits are provided at the ends of the wiring lines and at the places immediately before and after the input terminals, respectively, and then the circuit is interposed therebetween. Further, the protective circuits are provided around a circuit with a large current consumption.
