| titleOfInvention | Photosensitive diamine, polyamic acid or its derivatives, liquid crystal aligning agent, liquid crystal aligning film and liquid crystal display element |
| abstract | The invention provides a photosensitive diamine, polyamic acid or derivatives thereof, a liquid crystal aligning agent, a liquid crystal aligning film and a liquid crystal display element. The liquid crystal aligning agent of the present invention containing polyamic acid or derivatives thereof obtained by reacting a diamine component including a photosensitive diamine represented by formula (1) with tetracarboxylic dianhydride can form a high transmittance and orientation property. High liquid crystal alignment film. In formula (1), Ring A and Ring B are monocyclic hydrocarbons, condensed polycyclic hydrocarbons or heterocyclic rings; R is a linear alkylene group with 2 to 20 carbons, -COO-, -OCO-, ‑NHCO‑, or ‑N(CH 3 )CO‑; R 2 is a linear alkylene group with 2 to 20 carbons, ‑COO‑, ‑OCO‑, ‑CONH‑, or ‑CON(CH 3 )‑; R a to R d are independently -F, -CH 3 , -OCH 3 , -CF 3 , or -OH; a to d are integers of 0 to 4. |
