Title:
LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/026479
Kind Code:
A1
Abstract:
The present invention provides a liquid crystal display element in which the fall time of a liquid crystal is improved, thereby yielding exceptional high-speed response and allowing polymer networks to be formed at high sensitivity, even at relatively long UV irradiation wavelengths, without adversely affecting the voltage hold rate (VHR); it being possible to manufacture said display element exceptionally efficiently. Provided is a liquid crystal display element in which a liquid crystal composition that contains one or more liquid crystal compounds held between two transparent substrates contains a polymer or copolymer that is a cured polymerizable composition containing one or more polymerizable compounds and a photopolymerization initiator having a maximum absorption wavelength peak at 310‒380 nm; the polymerizable composition content relative to the total weight of the polymerizable composition and the liquid crystal composition being at least 1% by mass to less than 40% by mass.
