| description | A laminated polarizing film that is capable of enhancing a viewing angle of a liquid crystal display device, particularly in an IPS mode, is provided. The laminated polarizing film can be obtained by adhering a phase retardation film and a polarizing film by a roll-to-roll process. Specifically, the laminated polarizing film contains a negative substantially uniaxial optical film containing a thermoplastic polymer having a negative molecular polarizability anisotropy, a positive optical film containing a thermoplastic polymer having a positive molecular polarizability anisotropy, and a polarizing film, that are laminated at least in this order, a slow axis within a film plane of the negative substantially uniaxial optical film and a slow axis within a film plane of the positive optical film are substantially in parallel to each other, and each are substantially perpendicular to an absorption axis of the polarizing film, a positional relationship between a principal orientation direction of polymer main chains of the negative substantially uniaxial optical film and the absorption axis of the polarizing film is substantially in parallel, and a positional relationship between a principal orientation direction of polymer main chains of the positive optical film and the absorption axis of the polarizing film is substantially perpendicular. |
