Abstract

This liquid crystal display device is provided with: a pair of substrates which have conductive films, respectively; a liquid crystal layer which is arranged between the pair of substrates and contains a liquid crystal; and a liquid crystal control layer which is formed on the substrate-side interface of the liquid crystal layer by means of polymerization of a polymerizable monomer, and which controls the alignment of the liquid crystal. With respect to this liquid crystal display device, at least one of the pair of substrates is not provided with a liquid crystal alignment film, and the liquid crystal control layer contains a compound that has at least one partial structure which is selected from the group consisting of a fluorene structure-containing group, an aromatic amino group and a nitrogen-containing aromatic heterocyclic group.
