A liquid crystal display device having a pair of substrates, at least one of the substrates being transparent, a liquid crystal layer interposed between the pair of substrates, and pixel electrodes and common electrodes and active elements being arranged on at least one substrate between the pair of substrates. The liquid crystal of the liquid crystal layer is controlled to perform display by applying a voltage between the pixel electrode and the common electrode. An alignment layer is disposed on a surface in contact with the liquid crystal layer of each of the pair of substrates, and the alignment layer is made of an organic polymer selected from the group consisting of polyamic acid group polymers and polyimide ester group polymers having a relative imidization ratio above 60%. |
