Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/141824
Kind Code:
A1
Abstract:
The present invention provides a liquid crystal display device which is capable of maintaining a good VHR for a long period of time in a high temperature environment, while suppressing residual DC low and suppressing display defects such as spots and image burn-in.
A liquid crystal display device according to the present invention is provided with: a first substrate comprising a pixel electrode; a second substrate facing the first substrate; a liquid crystal layer sandwiched between the first substrate and the second substrate; an aromatic polyimide alignment film arranged on at least one of the first substrate and the second substrate; and a radical generation source which is capable of supplying radicals to the liquid crystal layer by means of light irradiation. The liquid crystal layer contains a liquid crystal compound having an alkenyl group; the aromatic polyimide alignment film contains at least one polymer selected from among polyimides and polyamic acids, and is arranged so as not to be in contact with the pixel electrode; and the at least one polymer has an aromatic tetracarboxylic acid dianhydride monomer unit.
