Abstract:
An active-matrix liquid crystal display device comprising:a pair of substrates at least one of which is transparent;a liquid crystal layer disposed between said pair of substrates;a group of electrodes for applying to said liquid crystal layer an electric field substantially parallel to the substrate plane and a plural number of active elements being formed on one of said pair of substrates; andan alignment layer disposed between said liquid crystal layer and at least one of said pair of substrates, wherein said alignment layer is a photo-reactive material layer, and said photo-reactive material layer is a photo-reactive alignment layer which has been subjected to linearly polarized light irradiation to selectively derive a photochemical reaction;wherein said alignment layer is made of an organic polymer having at least one of long-chain alkylene groups and fluoro groups selected from the group consisting of at least one of a polymer and an oligomer-amic acid imide, at least one of a polymer and an oligomer-imide, at least one of a polymer and an oligomer-imidosiloxane, and at least one of a polymer and an oligomer-amide-imide; andwherein at least one of said alignment layers is made of an organic polymer containing at least one of the polymer and oligomer in which the polymerizate of at least one of the long-chain alkylene groups and fluoro groups incorporated in the amine moiety or acid moiety is 5-30% of the total number of moles.
