Abstract
The purpose of the present invention is to prevent a decrease in light reflection characteristic and an increase in electric resistance due to oxidation of silver in a semiconductor device including an optical sensor in which silver is used for an anode of a photoconductive film. The present invention has a following structure to solve the problem: A semiconductor device includes a thin film transistor formed on a substrate. An electrode connected electrically to the thin film transistor is formed of a silver film. A first indium tin oxide (ITO) filmis formed on the silver film. An alumina (AlOx) filmis formed on the first ITO film
