Abstract:
An electronic unit, comprising:an electrooptical device, including: a substrate device, comprising, on a substrate, a first conductive film, a first insulating film formed over said first conductive film, a second insulating film bonded on said first insulating film, a conductive silicon film formed above said second insulating film, and a contact hole opened in said first and second insulating films to connect said first conductive film and said conductive silicon film, the contact hole penetrating through a bonding interface between said first insulating film and said second insulating film, a portion in said contact hole penetrating through said bonding interface not being eroded by an etch solution; an opposing substrate arranged opposite said substrate device; and an electrooptical substance sandwiched between said opposing substrate and said substrate device.
