Abstract

The invention discloses a liquid crystal aligning agent, a liquid crystal aligning film prepared by using the same and a liquid crystal display element prepared by using the liquid crystal aligning agent. The liquid crystal aligning agent contains at least one of polymers (A) with a repeating unit shown as a constitutional formula (I), and at least one of organic solvents (B); and the measured viscosity of the liquid crystal aligning agent at the temperature of 25 DEG C is between 5 and 40cps. In the constitutional formula (I), P is a bivalent organic group; and Q is a bivalent organic group.

Description

technical field

[0001] The invention relates to an alignment agent, in particular to a liquid crystal alignment agent, and a liquid crystal alignment film and a liquid crystal display element prepared therefrom. Background technique

[0002] Liquid crystal display elements were mainly used in the screens of notebook computers or desktop personal computers in the early days, and were also used in various liquid crystal display devices such as camera viewfinders and projection displays. In recent years, they have also been widely used in the production of televisions. machine. The industry generally uses nematic liquid crystal display elements as the mainstream. Among the nematic liquid crystal display elements, the types that are actually used are as follows: (1) The alignment direction of the liquid crystal on one side of the substrate is different from that on the other side. Twisted Nematic (TN) type liquid crystal display elements in which the liquid crystal alignment di...
