LAMINATED OPTICAL FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A laminated optical film reducing the change of a retardation value, a polarizer and a liquid crystal display device are provided to reduce the change of the retardation value of the whole thickness direction of the laminated optical film although retardation values of the thickness direction of the optical films comprising the layers of the laminated optical film change according to the temperature change. A liquid crystal display device comprises a polarizer and a liquid crystal cell. The polarizer comprises the optical film and the laminated polarized light device. The liquid crystal cell is the liquid crystal cell of the OCB(Optically Compensatory Bend) mode. The optical film comprises the first optically anisotropic layer, the second optically anisotropic layer and the third optically anisotropic layer. In case both sides of the first optically anisotropic layer and the second optically anisotropic layer are a roll form, it is adhered by a roll-to-roll process.
