Description

technical field

[0001] The invention relates to a liquid crystal aligning agent, a liquid crystal aligning film and a forming method thereof, a liquid crystal display element and a polymer. More specifically, it relates to a liquid crystal aligning agent capable of forming a liquid crystal aligning film capable of forming a liquid crystal aligning film with excellent pretilt angle stability by irradiation with polarized or non-polarized light rays; exhibiting good liquid crystal orientation and excellent pretilt angle stability A liquid crystal alignment film and a method for forming the same; and a liquid crystal display element with excellent long-term reliability. Background technique

[0002] So far, it is known that a nematic liquid crystal having positive dielectric anisotropy is sandwiched between substrates with transparent electrodes having a liquid crystal alignment film, and the long axes of liquid crystal molecules are continuously twisted between the substrates ...
