Abstract

La présente invention, selon un mode de réalisation, permet d'effectuer un alignement par addition d'un régulateur d'alignement à une couche d'alignement qui comprend une couche d'alignement horizontale ou la couche d'alignement horizontale et une couche d'alignement verticale sur un substrat. Par conséquent, l'invention procure un dispositif d'affichage à cristaux liquides à domaine multiple ayant une vitesse de réponse rapide et un excellent angle de vision dans la totalité de la plage de gradation.
