Abstract

La présente invention a trait à un panneau à cristaux liquides à phase bleue ainsi qu'à un dispositif d'affichage, et elle se rapporte aux domaines de la conception et de la fabrication de panneaux à cristaux liquides, afin de réduire la tension d'excitation d'un panneau à cristaux liquides à phase bleue. Le panneau à cristaux liquides à phase bleue comprend : des électrodes de pixel (006) situées sur un côté intérieur d'un premier substrat (001) et disposées en réseau ; une électrode commune (007) située sur un côté intérieur d'un second substrat (002) ; une première couche de prisme (101) se trouvant entre une couche de cristaux liquides à phase bleue (003) et un premier polariseur (004) ; ainsi qu'une seconde couche de prisme (102) se trouvant entre la couche de cristaux liquides à phase bleue (003) et un second polariseur (005). Une région de pixel, où se situent les électrodes de pixel (006), est divisée en une région de transmission et une région de réflexion. Pour une lumière incidente perpendiculaire au substrat, l'angle de réfraction de la partie de la lumière qui traverse la première couche de prisme (101) et qui se trouve dans la région de transmission est supérieur à l'angle de réfraction de la partie de la lumière qui traverse la seconde couche de prisme (102) et qui se trouve dans la région de réflexion, de sorte que les différences de chemin optique générées par la lumière de la région de transmission et par la lumière de la région de réflexion traversant la couche de cristaux liquides à phase bleue (003) sont identiques.
