Abstract

The liquid crystal display element includes: two transparent substrates, at least one of the two transparent substrates having an electrode; a liquid crystal composition sandwiched between the two transparent substrates and containing one or two or more liquid crystal compounds; and a copolymer included in the liquid crystal composition, the copolymer being a cured product of a polymerizable composition that contains two or more polymerizable compounds. The polymerizable compounds used include one or two or more polymerizable, photo-alignable compounds (Vn), and the content of the polymerizable composition is 1% by mass or more and less than 40% by mass based on the total weight of the polymerizable composition and the liquid crystal composition. The liquid crystal display element of the present invention is applicable to various operational modes such as TN, STN, ECB, VA, VA-TN, IPS, FFS, π cell, OCB, and cholesteric liquid crystal modes.
