Abstract
Provided are an electro-optical device and an electronic apparatus enabling a channel length of a transistor provided in a peripheral circuit to be set to an appropriate dimension even when a region available for disposing the peripheral circuit has a reduced width. A plurality of N-channel type transistors formed in a scan line drive circuit of an electro-optical device each include a light-shielding layer, an insulating layer, a semiconductor layer, a gate insulating layer, and a gate electrode laminated one on another in order on the one surface side of a first substrate, and a slit overlapping a channel region in planer view extends in a channel width direction to the light-shielding layer. Therefore, in the semiconductor layer, step part reflecting a shape of each of end portions of the light-shielding layer via the insulating layer extend in the channel width direction in the channel region.
