Abstract:
(EN) [Problem] To provide a liquid crystal display element which balances light-emission efficiency and color reproducibility, and is capable of suppressing or preventing deterioration of the liquid crystal layer thereof caused by high energy light ray irradiation. [Solution] A liquid crystal display element which is depicted in fig. 3 and equipped with a pair of substrates provided in a manner such that a first substrate and a second substrate face one another, a liquid crystal layer sandwiched between the pair of substrates, a pixel electrode provided on the first or second substrate, a common electrode provided on the other of the substrates, a light source unit, and a photoconversion layer which contains a light-emitting nanocrystal that has a light-emitting spectrum which is red (R), green (G) or blue (B) depending on the light from the light source unit, wherein the liquid crystal layer contains a polymer network (A), and a liquid crystal composition (B) containing a compound represented by general formula (i) (In the formula, Ri1 and Ri2 represent a C1-8 alkyl group or the like, Ai1 represents a 1,4-phenylene group or the like, and ni1 represents 0 or 1.) in the amount of 10-50 wt%.
(FR) Le problème décrit par la présente invention est de fournir un élément d'affichage à cristaux liquides qui équilibre l'efficacité d'émission de lumière et la reproductibilité des couleurs, et est capable de supprimer ou d'empêcher la détérioration de la couche de cristaux liquides de celui-ci provoquée par une irradiation par rayons lumineux à haute énergie. À cet effet, l'invention concerne un élément d'affichage à cristaux liquides qui est représenté sur FIG. 3. Et équipé d'une paire de substrats disposés de telle sorte qu'un premier substrat et un second substrat se font à face, une couche de cristaux liquides prise en sandwich entre la paire de substrats, une électrode de pixel disposée sur le premier ou le second substrat, une électrode commune disposée sur l'autre des substrats, une unité de source de lumière, et une couche de photoconversion qui contient un nanocristal électroluminescent qui a un spectre d'émission de lumière qui est rouge (R), vert (G) ou bleu (B) en fonction de la lumière provenant de l'unité de source de lumière, la couche de cristaux liquides contenant un réseau polymère (A), et une composition de cristaux liquides (B) contenant un composé représenté par la formule générale (i) (dans la formule, Ri1 et Ri2 représentent un groupe alkyle en C1-8 ou similaire, Ai1 représente un groupe 1,4-phénylène ou similaire, et ni1 représente 0 ou 1.) dans la quantité de 10 à 50 % en poids.
