Description

technical field

[0001] The present invention relates to a novel diamine having a triazine ring and side chain structure, a polymer obtained by reacting the diamine with tetracarboxylic dianhydride, and a liquid crystal alignment device containing the polymer agent, a liquid crystal alignment film formed from the liquid crystal alignment agent, and a liquid crystal display element having the liquid crystal alignment film. Background technique

[0002] Liquid crystal display elements are used in various liquid crystal displays such as monitors of notebook computers or desktop computers, view finders of video cameras, and projection displays. It is used in display devices, and recently it has also begun to be used as televisions. In addition, it can also be used as an optoelectronic-related element such as an optical printer head, an optical Fourier transform element, or a light valve. The mainstream of previous liquid crystal display elements is a display element using nemat...
