Abstract:
A semiconductor device comprising:a first substrate on which a pixel region of reverse stagger type thin film transistors, having an amorphous semiconductor and arranged in a matrix shape, is formed; a second substrate on which an opposing electrode corresponding to said pixel region is formed; a third substrate made from glass or quartz, formed in a region external to said first substrate, and having a driver circuit formed from a plurality of thin film transistors having a crystalline semiconductor; and a liquid crystal layer sandwiched between said first substrate and said second substrate, characterized in that: at least one end surface of a semiconductor layer of said reverse stagger type thin film transistor made from said amorphous semiconductor, and of a first conductive layer formed on said semiconductor layer, are formed in rough correspondence; a plurality of said third substrates are formed on said first substrate; and said plurality of thin film transistors having the crystalline semiconductor contain a first thin film transistor formed from a first gate insulating film and a second thin film transistor formed from a second gate insulating film.
