Abstract
An electro-optic device of the present disclosure includes a transistor disposed at a substrate. The transistor includes a semiconductor layer including a channel region, a source region, and a drain region and extending along a first direction, and a gate electrode facing the channel region via an insulating film. An impurity is added to a part of the channel region. In the first direction, an impurity concentration in a central region of the channel region and an impurity concentration in side regions at both sides of the central region are different from each other.
