Liquid crystal device employing polymer network on one substrate and alignment layer or polymer network on other substrate

A liquid crystal device comprising a pair of substrates, each substrate having an electrode layer and at least one of the substrates being transparent, one or both of said substrates having formed thereon a network layer having a three-dimensional network structure having continuous fine voids which comprises a transparent solid substance, 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 a small gap therebetween, and a liquid crystal material filled between said pair of substrates and filling said voids in the network structure.

A liquid crystal device as claimed in claim 13, wherein said dichroic dye is an anthraquinone dye.

A liquid crystal device comprising a pair of substrates, each substrate having an electrode layer and at least one of the substrates being transparent, one of said substrates having formed thereon a network layer having a three-dimensional network structure having continuous fine voids which comprises a transparent solid substance with the other substrate having formed thereon an alignment layer, said pair of substrates being assembled in such a manner that said network layer faces to said alignment layer in contact or with a small gap therebetween, and a liquid crystal material filled between said pair of substrates and filling said voids in the network structure.

A liquid crystal display having, as a transmission display or a projection display, a liquid crystal device comprising a pair of substrates, each substrate having an electrode layer and at least one of the substrates being transparent, both of said substrates having formed thereon a network layer having a three-dimensional network structure having continuous fine voids which comprises a transparent solid structure, and a liquid crystal material filled between said pair of substrates and filling said voids in the network structure.

A liquid crystal display having, as a transmission display or a projection display, a liquid crystal device comprising a pair of substrates, each substrate having an electrode layer and at least one of the substrates being transparent, one or both of said substrates having formed thereon a network layer having a three-dimensional network structure having continuous fine voids which comprises a transparent solid substance, 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 a small gap therebetween, and a liquid crystal material filled between said pair of substrates and filling said voids in the network structure.

A liquid crystal display having, as a transmission display or a projection display, a liquid crystal device comprising a pair of substrates each having an electrode layer and at least one of the substrates being transparent, one of said substrates having formed thereon a network layer having a three-dimensional network structure having continuous fine voids which comprises a transparent solid substance with the other substrate having formed thereon an alignment layer, said pair of substrates being assembled in such a manner that said network layer faces to said alignment layer in contact or with a small gap therebetween, and a liquid crystal material filled between said pair of substrates and filling said voids in the network structure.
