Claim Text:
1. An electro-optical device comprising: a semiconductor substrate having a first well, a second well having a same conductivity type as the first well, a first region and a second region, the first region and the second region having a conductivity type different from that of the first and second wells; a display unit including a plurality of pixel circuits, each of the pixel circuits including one or more transistors; and a driving circuit, including first conductivity type of transistors and second conductivity of transistors, that is disposed on the outside of the display unit to be distanced from the display unit and outputs a signal for driving the plurality of pixel circuits, wherein the one or more transistors are formed in the first well and a common substrate potential is supplied to the one or more transistors, the first conductivity type of transistors are formed in the second well, the second conductivity of transistors are formed in the first region, the first well and the second well are separated from each other by the second region, and the second well is formed between the first region and the second region.
