Abstract

To realize uniform display which is free of unevenness by making individual resistances of a plurality of wires formed on a substrate small as to a liquid crystal device. The substrate (12) for an electrooptical device has a base material (16b) and the plurality of wires (39a) formed on the base material (16b). At least one of the wires (39a) has a part where the wire width (WO) gradually increases from a first side (16c) to a second side 16f of the base material (16b) at a bending part (49b) of the wire (39a). Thus, the part where the wire width (WO) is wide is provided to reduce the wire resistance of the wire (39a) and then crosstalk is prevented from being generated in a display area of the electrooptical device.
