| titleOfInvention | Novel photofunctional polymer material and preparation method thereof and liquid crystal alignment film manufacturing method using the same |
| abstract | The present invention is azo-polyamic acid (azo-polyamic acid) represented by the following general formula (I) and azopolyimide (azo-polyimide) represented by the following general formula (II) and their preparation method, Nematic using them The present invention relates to a method for manufacturing a liquid crystal alignment film of ferroelectric and anti-ferroelectric LCDs. The difficulty in uniform alignment due to contamination caused by impurities generated by contact rubbing and electrostatic generation, reduced yield of products, lower contrast, and large area. Various problems can be solved through non-contact photoalignment using photochemical properties of the photosensitive polyimide.n n n ----- (Ⅰ)n n n ----- (Ⅱ)n n n In the above formula, , ,n n n , ,n n n , ,n n n or to be. |
