Abstract:
An electrooptical substrate device, comprising:a substrate; an insulator layer; an N-type single-crystal semiconductor layer formed above said insulator layer and including a P-type source region, a P-type drain region and a channel region; a gate electrode formed above said single-crystal semiconductor layer in said channel region through a gate insulating film; a scanning line connected to said gate electrode; a data line connected to one of said source region and said drain region; a pixel electrode connected to the other of said source region and said drain region, a P-channel transistor being architected by said single-crystal semiconductor layer, said gate insulating film and said gate electrode to switch-control said pixel electrode a peripheral circuit in a periphery of an image display region on which is formed said pixel electrode above said substrate, said peripheral circuit including an N-channel transistor, said N-channel transistor having a conductor layer to suck out carriers built up in the semiconductor layer thereof, and said P-channel transistor provided in said image display region not having a conductor layer to suck out carriers built up in the semiconductor layer thereof.
