ABSTRACT:
To suppress the occurrence of a failure caused by static electricity in the manufacturing process of an active matrix type display device in which an active matrix circuit and peripheral drive circuits are integrated on a glass substrate, a protective capacitor to be connected to a short ring is formed using a semiconductor layer made from the same material as the active layer of a thin film transistor present under the short ring. This protective capacitor has a function to absorb an electric pulse generated in the plasma using process. Discharge patterns are provided to prevent an electric pulse from affecting each circuit.
