| 摘要 |
The invention discloses a liquid crystal aligning agent, a liquid crystal display device, a liquid crystal alignment film, and a polyorganosiloxane compound, aiming at providing a liquid crystal aligning agent capable of meeting the requirements of voltage retention rate and lightproof of a liquid crystal display element with short photoelectric response time. The liquid crystal aligning agent comprises light orientation group and the polymer of a group indicated in formula (A1). In the formula A1, RA refers to methylene, alkylene with carbon number ranging from 2 to 30, phenylene, or cyclohexylidene, wherein part or all of the hydrogen atoms in the groups can be substituted. RB refers to a connecting group consisting of any one from the group composed of double bond, triple bond, ether bond, ester bond, and oxygen atom. RC refers to a group having at least two single-ring structures. a is 0 or 1. |
