Abstract
This invention is to improve the assembling precision of an electronic device including a functional member, other than an electrode, requiring alignment, such as a light shield member or a spacer. Such functional member is composed of aluminum or a metal principally composed of aluminum, deposited by a CVD process utilizing alkylaluminum hydride gas.
Claims7
An electronic device, comprising:
- a liquid crystal display comprising:
- a pair of substrates, a liquid crystal material disposed between said substrates, and a thin film device provided on one of said substrates;
- an insulating film disposed on said thin film device, said insulating film being provided with a hole which exposes a conductive or semiconductive portion of said thin film device;
- and
- a metallic body serving as a spacer;
- wherein said metallic body is formed on said conductive or semiconductive portion via said hole.
