Abstract

In a semiconductor device employing a glass substrate, the object of the present invention is to provide a high performance semiconductor device with a large screen at low cost, which prevents the semiconductor device from being contaminated by impurities from the glass substrate. In a semiconductor device comprising a blocking film provided in contact with a glass substrate and TFTs provided on the blocking film, the blocking film is characterized by being made of a tantalum oxide film.
