  • the liquid crystal material constituting the liquid crystal layer has been subjected to a high degree of management because impurities have a great influence on the electrical characteristics of the display device if the impurities remain in the material.
  • the alignment film directly affects the liquid crystal layer and the impurities remaining in the alignment film move to the liquid crystal layer, thereby affecting the electrical characteristics of the liquid crystal layer. The characteristics of the liquid crystal display device due to the impurities in the alignment film material are being studied.
  • the material such as the organic pigment used for the color filter layer is also assumed to have an influence on the liquid crystal layer due to impurities contained in the same manner as the alignment film material.

However, these methods are not significantly different from simply reducing the impurities in the pigment, and are insufficient as an improvement for resolving display defects even in the current state of progress in pigment purification technology.

Abstract

La présente invention concerne un dispositif d'affichage à cristaux liquides qui utilise un filtre coloré basé sur une composition de cristaux liquides spécifique et des pigments spécifiques. Ce dispositif d'affichage à cristaux liquides empêche les diminutions du rapport de maintien de tension (VHR) et les augmentations de la densité ionique (ID) dans une couche de cristaux liquides, et il résout les problèmes liés aux défauts d'affichage tels que les points blancs, les irrégularités d'orientation et l'image rémanente. Ledit dispositif d'affichage à cristaux liquides est caractérisé en ce qu'il empêche les diminutions du rapport de maintien de tension (VHR) et les augmentations de la densité ionique (ID) dans la couche de cristaux liquides, et en ce qu'il régule l'apparition de défauts d'affichage tels que l'image rémanente. Il s'avère donc utile pour les afficheurs à cristaux liquides à mode VA et mode PSVA en ce qui concerne la commande de matrice active, et il peut s'appliquer aux afficheurs à cristaux liquides tels que les télévisions, les écrans, les téléphones mobiles et les smartphones.
