Abstract:
1. A process for producing a liquid crystal cell substrate, which comprises the following steps [1] to [4] in this order: [1] laminating a transfer material on a substrate; [2] separating the support from the transfer material laminated on the substrate; and [3] exposing the photosensitive polymer layer disposed on the substrate to light; and [4] removing unnecessary parts of the photosensitive polymer layer and the optically anisotropic layer on the substrate, wherein said transfer material comprises at least one optically anisotropic layer and at least one photosensitive polymer layer on at least one support, said optically anisotropic layer comprises one or more compounds having a reactive group, said photosensitive polymer layer comprises two or more types of photopolymerization initiators having different photoreaction mechanisms to each other, and a compound having a reactive group which can react with one or more of the reactive groups present in the optically anisotropic layer by the action of at least one of said photopolymerization initiators, and the at least one optically anisotropic layer is arranged between the at least one support and the at least one photosensitive polymer layer.
