Provided is a liquid crystal display capable of realizing a quick responsibility, a high contrast ratio, a wide angle of visibility and a continuous gradation especially and altogether. The liquid crystal display is so made of a liquid crystal containing a compound having a bent structure to exhibit a smectic phase that the compound molecules have a longer axis forming a structure normal to a substrate, and is driven by applying an electric field in parallel with the substrate. The aforementioned bent structure is preferred to have an angular shape. L'invention concerne un affichage à cristaux liquides offrant un temps de réponse rapide, un fort contraste, un grand angle d'observation et une gradation continue. L'affichage à cristaux liquides est constitué de cristaux liquides contenant un composé présentant une structure courbe à phase smectique telle que ses molécules possèdent un axe plus long formant une structure normale à un substrat, et est excité par application d'un champ électrique parallèlement au substrat. Ladite structure courbe prend de préférence une forme angulaire.
