Abstract
The present invention relates to a configuration of a display element and forms switching circuits or peripheral circuits for driving pixels by transferring/disposing a semiconductor circuit formed on another substrate and disposes high performance transistors on the display substrate. The present invention also relates to a process of forming a circuit having switching elements for driving pixels and peripheral circuits for sending drive signals thereto on the substrate of the display element. A separation layer is formed on a second substrate and a semiconductor film is formed thereon. This semiconductor film having predetermined semiconductor circuits formed therein is bonded to the substrate of the display element and then electrical connection with a wire on the substrate is effected.
