Abstract

A liquid crystal display device includes an illuminator and a liquid crystal panel for performing displaying by using light which is emitted from the illuminator. The liquid crystal panel includes a pair of substrates and a liquid crystal layer provided therebetween. The liquid crystal layer is formed of a liquid crystal material which contains molecules having at least one of a carbon-carbon triple bond and a polycyclic group. The illuminator includes a light source causing primary generation of at least blue light, among other light which is used for displaying.

Claims
