1. A liquid crystal display device comprising a pair of substrates, at least one of said substrates being transparent;

  • a liquid crystal layer interposed between said pair of substrates; and

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