Title (EN) POLARIZING PLATE AND IMAGE DISPLAY DEVICE INCLUDING SAME
(FR) PLAQUE POLARISANTE ET DISPOSITIF D'AFFICHAGE D'IMAGES LA COMPRENANT
(KO) 편광판 및 이를 포함하는 화상 표시 장치
Abstract: front page image
(EN)The present invention relates to a polarizing plate and an image display device including the same and, more specifically, to a polarizing plate and an image display device including the same, wherein the polarizing plate comprises a polyvinyl alcohol-based polarizer and a protection substrate, which is positioned on at least one surface of the polarizer and includes a polyvinyl acetate-based resin and a cellulose-based resin. Accordingly, the polarizing plate allows a display device including the same to be weight-reduced in a form of a thin film. Further, a small physical property difference between the polarizer and a coating layer allows the polarizing plate to prevent a problem of deterioration of an optical characteristic according to a refractive index difference, etc. and problems, such as a flexion and a crack which may occur when the polarizing plate is cut or exposed to a severe environment. In addition, the polarizing plate includes the protection substrate having an excellent tensile strength and thus allows axis-twisting of the polarizer due to the contraction of the polarizer to be controlled so as to prevent problems, such as a curl and deterioration of polarizability.
(FR)La présente invention concerne une plaque polarisante et un dispositif d'affichage d'image la comprenant et, plus particulièrement, une plaque polarisante et un dispositif d'affichage d'image la comprenant, la plaque polarisante comprenant un polariseur à base d'alcool polyvinylique et un substrat de protection, qui est positionné sur au moins une surface du polariseur et qui comprend une résine à base d'acétate de polyvinyle et une résine à base de cellulose. Par conséquent, la plaque polarisante permet à un dispositif d'affichage la comprenant d'avoir un poids réduit sous la forme d'une couche mince. En outre, une faible différence de propriété physique entre le polariseur et une couche de revêtement permet à la plaque polarisante d'empêcher un problème de détérioration d'une caractéristique optique selon une différence d'indice de réfraction, etc., et des problèmes, tels qu'une flexion et une fissuration qui peuvent se produire lorsque la plaque polarisante est coupée ou exposée à un environnement rude. De plus, la plaque polarisante comprend le substrat de protection ayant une excellente résistance à la traction et permet ainsi une torsion axiale du polariseur due à la contraction du polariseur à commander de façon à empêcher des problèmes, tels qu'un gondolage et une détérioration de la polarisabilité.
