Abstract
This invention provides a semiconductor device that does not cause a defect at an intersection of wirings even when a surge voltage enters from a signal input terminal, an electro-optic device provided with the semiconductor device as a TFT array substrate, and an electronic instrument. In a TFT array substrate of a liquid crystal device, a signal input terminal, and terminals are arranged along a substrate side, and a signal input line extends from the signal input terminal to a substrate side. Of constant potential lines that supply constant potential to an electrostatic protection circuit for the signal input line, a low potential line does not at all intersect the signal input line, and a high potential line, though intersecting the signal input line, does not intersect a wiring portion from the signal input terminal to the electrostatic protection circuit. Accordingly, even when a surge voltage enters from the signal input terminal, heat generation is not caused at an intersection between the signal input line and the low potential line by surge voltage.
