Abstract:
1. A semiconductor device comprising: a first substrate having a pixel region; thin film transistors arranged in a matrix form over said first substrate in said pixel region, each of said thin film transistors having a channel region comprising amorphous semiconductor; a second substrate opposed to said first substrate; an opposing electrode formed over said second substrate and opposed to said pixel region; a first driver circuit for driving scanning lines comprising at least two third substrates over a first region outside said pixel region of said first substrate; a second driver circuit for driving data lines comprising at least two fourth substrates over a second region outside said pixel region of said first substrate; at least one first thin film transistor and at least one second thin film transistor on each of the at least two third substrates and the at least two fourth substrates; a liquid crystal layer interposed between said first substrate and said second substrate, wherein said first thin film transistor and said second thin film transistor formed on the at least two third substrates and the at least two fourth substrates have a first gate insulating film and a second gate insulating film, respectively, and said first gate insulating film is thinner than said second gate insulating film.
