Patent ID: 8223093

Claim:
An electro-optical device comprising an element substrate having: a first signal line extending in a first direction; a second signal line extending in a second direction crossing the first direction; a first pixel electrode electrically connected to the first signal line; a second pixel electrode electrically connected to the first signal line and adjacent to the first pixel electrode; a first field-effect transistor electrically connecting the first pixel electrode to the first signal line; and a second field-effect transistor electrically connecting the second pixel electrode to the first signal line; wherein the first field-effect transistor includes a first semiconductor layer extending in a direction crossing the second direction, wherein the second field-effect transistor includes a second semiconductor layer extending in the direction crossing the second direction, wherein the first semiconductor layer and the second semiconductor layer are displaced from each other in the second direction, and wherein an end of the first semiconductor layer facing toward the second pixel electrode is adjacent to an end of the second semiconductor layer facing toward the first pixel electrode or is closer to the second pixel electrode than the end of the second semiconductor layer facing toward the first pixel electrode.
