Problems solved by technology

It is known that when a voltage is applied to the display component, the generated ionic charge will be absorbed by the liquid crystal alignment film of the display component. When the applied voltage is released, the ionic charge is difficult to detach from the alignment film, thus causing an internal electric field phenomenon and causing the screen to appear. Afterimage problem

Embodiment Construction

[0038] Herein, a range indicated by "one value to another value" is a general representation to avoid enumerating all values ​​in the range in the specification. Therefore, the description of a specific numerical range covers any numerical value in the numerical range and the smaller numerical range bounded by any numerical value in the numerical range, as if the arbitrary numerical value and the smaller numerical value are expressly written in the specification. same range. For example, the range of "the content is 10 to 80% by weight" includes the range of "the content is 50 to 60% by weight" regardless of whether other numerical values ​​are listed in the description.

[0039] Herein, if it is not specified whether a certain group is substituted, the group may represent a substituted or unsubstituted group. For example, "alkyl" can mean substituted or unsubstituted alkyl. In addition, when a group is described with "CX", it means that the main chain of the group has X car...

Abstract

A polymer comprising a unit represented by formula 1-1 or formula 1-2: formula 1-1, formula 1-2; and a unit represented by formula 2, formula 2, wherein R1 is a tetravalent organic group, R2 and R4 are divalent organic groups respectively, and R3 is a divalent organic group different from >R1(OH)2; the unit represented by formula 1-2 is obtained by dehydration and cyclization of the unit represented by formula 1-1 unit.

Description

technical field [0001] The present invention relates to a polymer, and in particular to a polymer containing a specific unit, a liquid crystal aligning agent containing the polymer, a liquid crystal aligning film made of the aforementioned liquid crystal aligning agent, and a liquid crystal aligning film having the aforementioned liquid crystal aligning film LCD components. Background technique [0002] The operating principle of a liquid crystal display is to use an external electric field to change the alignment state of liquid crystal molecules, thereby causing changes in the polarization state and direction of light, thereby obtaining a display effect of light and dark contrast. Due to the advantages of small size, light weight, low power consumption and good display quality, liquid crystal displays have become the mainstream of flat panel displays in recent years. [0003] With the expansion of the screen size, liquid crystal display components in which each pixel is e...
