Abstract

See full text

A liquid crystal light control element that controls a light absorption state by voltage application, the liquid crystal light control element including: a liquid crystal layer containing a liquid crystal composition between a pair of substrates each having an electrode; and a liquid crystal alignment film that is provided on at least one of the substrates and aligns a liquid crystal vertically,

    wherein the liquid crystal composition contains a liquid crystal and a dichroic dye,the liquid crystal alignment film is obtained from a liquid crystal aligning agent containing a polyimide precursor in which a diamine having a specific side chain is used as a part of the raw material or a polyimide obtained by imidizing the polyimide precursor, andthe proportion of the diamine used is 50 to 100 mol % based on the entire diamine component.
