Abstract: It is an object of the invention to provide a method for manufacturing a long laminated polarizing plate having a long polarizing coating formed by coating directly on a long retardation film and to provide such a long laminated polarizing plate. The present invention relates to a method for manufacturing a long laminated polarizing plate comprising a long retardation film having a slow axis in its longitudinal direction and a long polarizing coating placed on the retardation film and having an absorption axis or a transmission axis in an in-plane direction at an angle of 25 to 65° to the slow axis direction of the long retardation film, the method comprising the steps: (A) preparing a long retardation film having a slow axis in its longitudinal direction and having an Nz coefficient of 1.5 or less, wherein the Nz coefficient is expressed by the formula (nx−nz)/(nx−ny), wherein nx is a maximum in-plane refractive index of the film, ny is an in-plane refractive index of the film in a direction perpendicular to the direction in which nx is obtained, and nz is a refractive index of the film in its thickness direction; (B) rubbing the long retardation film, which is obtained in the step (A), in an in-plane direction at an angle of 20 to 70° to the longitudinal direction while feeding the long retardation film; and (C) forming a coating of a liquid crystal compound solution in an isotropic phase state on the rubbed surface of the long retardation film obtained in the step (B) and solidifying the coating to form a long polarizing coating in which the liquid crystal compound is oriented.
