ABSTRACT:
A liquid crystal device is formed by disposing a liquid crystal between a pair of substrates each having thereon an electrode pattern. At least one of the substrates is provided with an insulating film comprising a first insulating layer formed by wet-coating and baking, and a second insulating layer formed by vacuum deposition closer to the liquid crystal than the first insulating layer. The insulating film stably has an excellent dielectric strength, so that the productivity and production yield of the liquid crystal device can be improved. Further, the insulating film allows less strict control of production environment and time after the formation, so that the production cost can be reduced.
