发明名称 LIQUID CRYSTAL ALIGNING AGENT, METHOD FOR FORMING LIQUID CRYSTAL ALIGNMENT FILM AND LIQUID CRYSTAL DISPLAY DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a liquid crystal aligning agent which aligns liquid crystal molecules perpendicular to the rubbing direction by certain rubbing treatment to generate 0 deg. pretilt angle, which has good baking property and a high voltage holding rate, and/or which aligns liquid crystal molecules parallel to the polarization direction by the aligning treatment by irradiation of polarized pulse laser. SOLUTION: The liquid crystal aligning agent contains at least one kind of polymer selected from a group consisting of polyamic acid obtained by the reaction of tetracarboxylic acid dianhydrides expressed by formula (I) and diamine compounds and consisting of imidized polymers obtained by dehydrating and ring closing the above polyamic acid. In formula (I), R1 and R2 are same or different and each represents a univalent organic group or halogen atom, each of a and b is an integer 0 to 5, and when a plurality of R1 and R2 are present, they may be same or different.
