Title:
SPONTANEOUS ALIGNMENT AID FOR LIQUID CRYSTAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/003936
Kind Code:
A1
Abstract:
Provided is a liquid crystal composition which can ensure storability when added to a liquid crystal composition and allows vertical alignment of liquid crystal molecules even without the provision of a PI layer. Since this liquid crystal composition contains a compound represented by formula (i), and in particular, a compound having a structure in which Ki1 in formula (i) is represented by any one among formulae (K-1) to (K-3), the liquid crystal composition can be adsorbed on substrates sandwiching a liquid crystal composition (liquid crystal layer) and hold liquid crystal molecules in a vertically aligned state when used in a liquid crystal composition. Accordingly, a liquid crystal composition using the compound of the present invention allows alignment of liquid crystal molecules (vertical alignment of liquid crystal molecules when no voltage is applied, and horizontal alignment of liquid crystal molecules when a voltage is applied) even without the provision of a PI layer.
