摘要： Disclosed herein is an very thin achromatic quarter wave film laminate for transflective LCD included in an LCD polarizer. More specifically, the very thin achromatic quarter wave film laminate for transflective LCD has a considerably reduced thickness, as compared to conventional quarter wave films in which anisotropic polymeric films are laminated.

摘要： There is provided a novel composition for an alignment film having excellent adhesiveness to a liquid crystal layer as well as to a substrate when a cycloolefin-based aligned film (COP) is used as the substrate instead of triacetyl cellulose (TAC) that is used as a conventional substrate for an optical film whose optical properties are significantly deteriorated when it is used under hot and humid environments. The composition for an alignment film that is used for splay alignment includes polyvinyl alcohol (PVA); 13 to 25% by weight of an aery late monomer based on the weight of the polyvinyl alcohol; 20 to 30 % by weight of a compatibilizing agent based on the weight of the acrylate monomer; and 10 to 50% by weight of an aqueous photo initiator based on the weight of the acrylate monomer.

摘要： Provided are a circular polarizer and a reflective liquid crystal display including the same. The circular polarizer includes a polarizer comprising a polarizing film in which an absorption axis has an angle of about 85° to about 95° with respect to a liquid crystal alignment direction of a liquid crystal cell, where, in CIE coordinates, a color “a” is about −1 to about −0.6 and a color “b” is about 0.3 to about 2.5 and a ¼ wavelength plate in which an optical axis has an angle of about 130° to about 140° with respect to the liquid crystal alignment direction of the light crystal cell. When the circular polarizer is used, the visibility and color tone of the reflective liquid crystal display may be improved.
