The invention provides a liquid crystal panel substrate having transistors and reflectors connected to the transistors on a substrate to allow bright reflection display of high quality at wide viewing angles by providing the most suitable reflection characteristics to the reflectors. Under the reflectors, first conductive layers are overlaid in regions corresponding to the reflectors and formed in a concave-convex condition by forming a large number of openings.

A substrate device has, on a substrate, a first conductive film, a first insulating film formed thereon, a second insulating film bonded thereon, and a second conductive film formed thereon. A contact hole connecting the first and second conductive films is opened so as to penetrate through a bonding interface thereof. The area of the contact hole penetrating through the bonding interface is not eroded by an etching solution. Thus, where manufacturing a substrate device in which a contact hole penetrating through a bonding interface needs to be formed, it is unlikely that a defect will occur in the area where the contact hole passing through the bonding interface, thereby enhancing device reliability and manufacturing yield.
