Patent ID: 7095082

Claim:
An electrooptical device comprising: a first substrate comprising a display section provided with pixel electrodes and a peripheral-driving-circuit section provided on the periphery of the display section, a second substrate, and an optical material disposed between the first substrate and the second substrate; wherein a gate section comprising a gate electrode and a gate-insulating film is formed on one surface of the first substrate, a compound layer having high lattice matching with single-crystal silicon is formed on said one surface of the first substrate, and a single-crystal silicon layer is formed on the first substrate including the compound layer and the gate section; the single-crystal silicon layer constitutes a channel region, a source region, and a drain region; and a first bottom-gate thin-film transistor having the gate section is formed below the channel region, the first bottom-gate thin-film transistor constituting at least a part of the peripheral-driving-circuit section.
