Abstract
The present invention provides a liquid crystal display device that can sufficiently prevent crystallization of a liquid crystal material at low temperatures, and thereby has high response performance suitable for applications such as HMDs. The liquid crystal display device includes: paired substrates; a liquid crystal layer held between the substrates; and a photo-alignment film disposed on a surface facing the liquid crystal layer of at least one of the substrates, the liquid crystal layer containing a liquid crystal material that has a nematic-isotropic phase transition temperature of 75° C. or lower and a nematic phase temperature range narrower than 100° C., the photo-alignment film containing a polymer, the polymer and/or another component of the photo-alignment film containing a hydrophobic group.
