Abstract:
1. An electrooptic device comprising: a data line and a scanning line intersecting each other; a pixel electrode corresponding to the intersection of the data line and the scanning line; a transistor disposed in the intersection area corresponding to the intersection, the transistor including (i) a semiconductor layer having a channel region extending in a first direction in which the data line extends, the semiconductor layer including a first source drain region that is electrically connected to the data line, a second source drain region that is electrically connected to the pixel electrode, a first junction region formed between the channel region and the first source drain region, and a second junction region formed between the channel region and the second source drain region, and (ii) a gate electrode disposed in a layer on the opposite side of the semiconductor layer than the scanning line, the gate electrode overlapping with the channel region; and a first insulating layer between the semiconductor layer and the scanning line, the first insulating layer having a contact hole for electrically connecting the gate electrode and the scanning line, the contact hole having a first portion located beside the semiconductor layer of the corresponding transistor in plan view and that extends in the first direction along the second junction region and a second portion that overlaps with part of the scanning line and that extends in a second direction that is different from the first direction.
