Abstract
A liquid crystal display device includes an alignment sustaining layer formed of a photopolymerized material on each of surfaces of a pair of alignment films which are closer to a liquid crystal layer. The alignment sustaining layer is configured to regulate a pretilt azimuth of a liquid crystal molecule of the liquid crystal layer during absence of an applied voltage. A nematic liquid crystal material of the liquid crystal layer comprise a liquid crystal compound having a terphenyl ring system as an indispensable component, and the liquid crystal layer further comprises part of a photopolymerizable compound. A content of the photopolymerizable compound relative to the nematic liquid crystal material is less than 0.015 mol %.
