Claim Text:
1. An electro-optical substrate comprising: a scanning line; a data line; a pixel which is disposed at a position corresponding to an intersection of the scanning line and the data line; a driving circuit which includes a first circuit block and a second circuit block; a first power wiring line which is electrically connected to the first circuit block; and a second power wiring line which is electrically connected to the second circuit block; and a third power wiring line which is electrically connected to the first circuit block and the second circuit block, the first circuit block including at least one of a clock control circuit, a clock generating circuit, a unit shift circuit, a logic circuit, an inverter circuit and a transfer circuit, the second circuit block including at least one of a level shift circuit that amplifies a low-amplitude signal to a high-amplitude signal, a buffer circuit, a DA converter circuit and a LAT circuit, the first power wiring line having a first width and supplying a first potential to the first circuit block, the second power wiring line having a second width and supplying a second potential lower than the first potential to the second circuit block the third power wiring line having a third width and supplying a third potential higher than the first potential and the second potential to the first circuit block and the second circuit block, and the first width of the first power wiring line being narrower than the second width of the second power wiring line.
