Abstract:
(EN) Provided is a liquid crystal display element which has excellent properties such as display characteristics and electrical characteristics and is suitable for use in a large-screen high-definition liquid crystal television receiver and the like. This liquid crystal display element is provided with: a polarizing plate; and a liquid crystal cell that comprises liquid crystals between substrates with a liquid crystal structure stabilization film, said substrates being arranged so that films for stabilizing a liquid crystal structure, which have an average surface roughness Ra of 1.0 nm or less and contain at least one polymer selected from the group consisting of polyamic acids containing a side chain structure, polyamic acid esters containing a side chain structure and polyimides obtained by imidizing polyamic acids or polyamic acid esters, and an additive that is capable of improving rubbing resistance, face each other.
(FR) L'invention concerne un élément d'affichage à cristaux liquides qui a d'excellentes propriétés, telles que des caractéristiques d'affichage et des caractéristiques électriques, et est adapté à l'utilisation dans un téléviseur à cristaux liquides à haute définition à grand écran et analogue. L'invention concerne un élément d'affichage à cristaux liquides qui comprend : une plaque polarisante; et une cellule à cristaux liquides qui comprend des cristaux liquides entre des substrats avec un film de stabilisation de structure de cristaux liquides, lesdits substrats étant disposés de telle sorte que des films permettant de stabiliser une structure de cristaux liquides, qui ont une rugosité de surface moyenne Ra de 1,0 nm ou moins et comprennent au moins un polymère choisi parmi le groupe constitué d'acides polyamiques comprenant une structure de chaîne latérale, d'esters d'acide polyamique comprenant une structure de chaîne latérale, et de polyimides obtenus par imidation d'acides polyamiques ou d'esters d'acide polyamique, et un additif qui est apte à améliorer la résistance au frottement, se font mutuellement face.
(JA) 表示特性、電気特性等の諸性能に優れ、大画面で高精細の液晶テレビなどに好適に利用できる液晶表示素子を提供する。 側鎖構造を含有するポリアミック酸、側鎖構造を含有するポリアミック酸エステル、及び前記ポリアミック酸又はポリアミック酸エステルをイミド化したポリイミドからなる群から選ばれる少なくとも1種の重合体と、ラビング耐性を向上させることのできる添加剤とを含有し、表面平均面粗さRaが1.0nm以下である、液晶構造体を安定化するための膜が対向するように配置された、液晶構造体安定化膜付き基板の間に液晶を含む液晶セルと、偏光板とを備えた液晶表示素子とする。
