Title:
METHOD FOR PRODUCING LIQUID CRYSTAL CELL, AND LIQUID CRYSTAL CELL
Document Type and Number:
WIPO Patent Application WO/2018/066503
Kind Code:
A1
Abstract:
This method for producing a liquid crystal cell comprises: a thin film formation step wherein a thin film is formed on the surface of at least one of a pair of substrates with electrodes, which are composed of a TFT substrate and a slot substrate, said TFT substrate comprising a first dielectric substrate, a plurality of TFTs supported by the first dielectric substrate, and a plurality of patch electrodes electrically connected to the TFTs, and said slot substrate comprising a second dielectric substrate and a plurality of slot electrodes supported by the second dielectric substrate and having slots, in such a manner that the patch electrodes and/or the slot electrodes are covered by the thin film; and a light irradiation step wherein the thin film is irradiated with light containing p-polarized light so as to achieve an alignment film that is obtained by imparting the thin film with an alignment control ability for aligning liquid crystal molecules. This method for producing a liquid crystal cell is characterized in that the thin film contains a polymer which has a photoreactive functional group and exerts the alignment control ability of the thin film in a direction that is perpendicular to the polarization axis of the p-polarized light.
