Patent ID: 8450739

Claim:
An electrooptical device substrate, comprising: a first insulating film provided on a substrate; a plurality of pixels; a first concave portion provided in the first insulating film over the plurality of pixels; a second concave portion provided in the first insulating film on a bottom surface of the first concave portion; a thin film transistor containing an organic semiconductor layer provided in the second concave portion, a gate insulating film of the thin film transistor provided in the first concave portion and on the organic semiconductor layer, and a gate electrode provided in the first concave portion and on the gate insulating film, the thin film transistor being matched to one pixel among the plurality of pixels; a scanning line which is provided at an upper side with respect to the gate insulating film and provided in the first concave portion over the plurality of pixels; and a data line electrically connected to the thin film transistor.
