Title (EN) MIRROR DISPLAY
(FR) AFFICHEUR À MIROIR
(JA) ミラーディスプレイ
Abstract:
(EN) The present invention provides a mirror display wherein color shift in reflected colors of the mirror display at a frontal viewing angle and an oblique viewing angle is suppressed while taking advantage of using cholesteric liquid crystal layers in a half mirror layer. This mirror display is provided with a half mirror plate and a display panel disposed on the back surface side of the half mirror plate. The half mirror plate has a first visible light reflecting cholesteric liquid crystal layer and an infrared light reflecting cholesteric liquid crystal layer.
(FR) L'invention concerne un afficheur à miroir dont le décalage de couleurs des couleurs réfléchies à un angle de vision frontal et à un angle de vision oblique est supprimé, et qui profite de l'utilisation de couches de cristaux liquides cholestériques dans une couche demi-miroir. Cet afficheur à miroir est pourvu d'une plaque demi-miroir, et d'un panneau d'affichage disposé sur le côté surface arrière de la plaque demi-miroir. Ladite plaque demi-miroir comprend une première couche de cristaux liquides cholestériques réfléchissant la lumière visible, et une couche de cristaux liquides cholestériques réfléchissant la lumière infrarouge.
(JA) 本発明は、ハーフミラー層にコレステリック液晶層を用いる利点を生かしつつ、正面視角と斜め視角でのミラー表示の反射色の色ずれが抑制されたミラーディスプレイを提供する。本発明のミラーディスプレイは、ハーフミラープレートと、上記ハーフミラープレートの背面側に配置された表示パネルとを備え、上記ハーフミラープレートは、第1の可視光反射コレステリック液晶層、及び、赤外光反射コレステリック液晶層を有する。
