摘要: A polarizer protective film of the present invention comprises a thermoplastic resin layer having a moisture permeability of 100 g/m2/24 hours or less; and a resin layer that contains a nylon resin and is laminated on the thermoplastic resin layer. The polarizer protective film can have good adhesion to a polarizer when it is bonded to the polarizer through an adhesive layer to form a polarizing plate, and can form a polarizing plate with good polarization properties.

摘要: A polarizer protective film of the present invention comprises a thermoplastic resin layer having a moisture permeability of 100 g/m2/24 hours or less; and a resin layer that comprises a copolymer containing a styrene monomer unit and is laminated on the thermoplastic resin layer through an adhesive resin layer. The polarizer protective film can have good adhesion to a polarizer when it is bonded to the polarizer through an adhesive layer to form a polarizing plate, and can form a polarizing plate with good polarization properties.

摘要: A method for manufacturing a novel tilt alignment type optical compensation film formed using a non-liquid crystal polymer material, instead of a conventional tilt alignment type optical compensation film using a liquid crystal material. The method for manufacturing including: melting a non-liquid crystal polymer to prepare a molten resin; applying a shear force to the melted non-liquid crystal polymer by a shear force application device, thereby forming a film having an optical axis that tilts with respect to a thickness direction of the film; and stretching the film. The step of forming the film is carried out under conditions where a temperature T3 of the melted non-liquid crystal polymer, a glass transition point Tg of the non-liquid crystal polymer, and a temperature T2 of the shear force application device satisfy relationships represented by the following formulae (A) and (B): T3>Tg+25° C.; and (A) T3>T2.
