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