摘要： PURPOSE:To obtain a rubbing-less oriented film having high durability by forming a thin film of a specified compd. on a substrate and polymerizing with linearly polarized light. CONSTITUTION:A film comprised of a compd. for formation of an orient, film is formed on a substrate of a liquid crystal display element consisting of a transparent glass or plastic insulating body on which a transparent conductive film is formed. Photopolymerizable polyamic acids expressed by formula are used for the compd. In formula, A is a cyclobutane ring or quadrivalent aromatic hydrocarbon residue, B is a bivalent aromatic hydrocarbon residue, R and R are hydrogen or alkyl groups of 1-5 carbon atoms, E is a residue having double bonds which can be successively photopolymerized. This compd. is dissolved in a solvent and applied on the substrate by spin coating method or the like and exposed to linearly polarized light in a UV region to polymerize. After polymn., a part to relate to polymn., namely, a residue having double bonds or the like is removed by heating or using a solvent. Thus, heat resistance and light resistance are improved.

摘要： PURPOSE:To provide a liquid crystal display element which is bright and good in contrast over a wide temperature difference range and has a wide view angle by providing a means which varies a driving voltage according to detected temperature and a means which varies a frame frequency. CONSTITUTION:The liquid crystal display device is equipped with a liquid crystal layer 9 sandwiched between substrates 4 and 4b with a couple of transparent electrodes 5a and 5b having parallel arranged orientation control films 7a and 7b and a driving circuit 10 which performs multiplex driving by applying a voltage between the transparent electrodes 5a and 5b. This display device is equipped with a means which reduces the driving voltage and increases the frame frequency as the temperature rises. For the variation in frame frequency, a frequency division ratio for setting the relation between, for example, the temperature and frame frequency is written in a program counter from a microcomputer to vary the frequency of a clock signal inputted a liquid crystal controller and then the frame frequency of a liquid crystal cell is therefore varied.
