Title (EN) LIQUID CRYSTAL DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶表示装置
Abstract:
(EN) Provided is a low-cost liquid crystal display device which has excellent visibility. A liquid crystal display device which sequentially comprises a backlight light source, a light source-side polarizing plate, a liquid crystal cell and a viewing-side polarizing plate in this order, and which is characterized in that: each of the light source-side polarizing plate and the viewing-side polarizing plate has a configuration wherein a polarizer protective film is laminated on at least one surface of a polarizer, while having an adhesive layer for bonding the polarizing plate with the liquid crystal cell; the viewing-side polarizing plate contains an ultraviolet absorbent; and the light source-side polarizing plate does not contain an ultraviolet absorbent.
(FR) L'invention a trait à un dispositif d'affichage à cristaux liquides bon marché qui présente une excellente visibilité. Le dispositif d'affichage à cristaux liquides comprend successivement une source de lumière de rétroéclairage, une plaque de polarisation côté source de lumière, une cellule à cristaux liquides, et une plaque de polarisation côté visualisation, dans cet ordre, et il est caractérisé en ce que : la plaque de polarisation côté source de lumière et la plaque de polarisation côté visualisation possèdent une configuration dans laquelle un film protecteur de polariseur est stratifié sur au moins une surface d'un polariseur, tout en présentant une couche adhésive destinée à assembler la plaque de polarisation avec la cellule à cristaux liquides ; ladite plaque de polarisation côté visualisation contient un absorbant d'ultraviolets ; et ladite plaque de polarisation côté source de lumière ne contient pas d'absorbant d'ultraviolets.
(JA) 低コストで視認性に優れた液晶表示装置を提供する。バックライト光源、光源側偏光板、液晶セル及び視認側偏光板をこの順に有する液晶表示装置であって、光源側偏光板及び視認側偏光板は、各々、偏光子の少なくとも一方の面に偏光子保護フィルムが積層されており、かつ、液晶セルと貼り合せるための粘着剤層を有する構成であり、視認側偏光板は紫外線吸収剤を含有し、光源側偏光板は紫外線吸収剤を含有しないことを特徴とする、液晶表示装置。
