Abstract
A liquid crystal device comprising a pair of substrates each having an electrode layer at least one of which is transparent, one or both of said substrates having formed thereon a network layer having a three-dimensional network structure which comprises a transparent solid substance, or one of said substrates having formed thereon said network layer with the other substrate having formed thereon an alignment layer, said pair of substrates being assembled in such a manner that said network layer of one substrate faces to the other network layer or the other substrate with or without an alignment layer in contact or with a small gap therebetween, and a liquid crystal material filled between said pair of substrates.
