Title:
ALIGNMENT AID, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/008896
Kind Code:
A1
Abstract:
Provided are an alignment aid capable of sufficiently exerting an alignment regulating force that vertically aligns liquid crystal molecules and preventing a change in pretilt angle with time, a liquid crystal composition including the alignment aid, and a liquid crystal display device. The alignment aid of the present invention has a function of spontaneously aligning liquid crystal molecules. This alignment aid has a wavelength of the longest wavelength side having an absorbance of 0.5 at 330 nm or less in the light absorption spectrum thereof. The light absorption spectrum is preferably measured with a solution in which the alignment aid is dissolved in tetrahydrofuran so as to have a concentration of 1000 ppm.
