Abstract:
1. A method of producing a laminate polarizing plate in which a phase retarder film comprising at least one coating layer having refractive index anisotropy is laminated on a polarizing film having an adhesive layer at a side of said adhesive layer, wherein the method comprises a step of preparing the polarizing film having the adhesive layer, separately a first step of forming the coating layer on a transfer substrate having a mould release treatment surface and having a water contact angle of the mould release treatment surface of 90 to 130°, being followed by laminating an opposite surface of the coating layer to the transfer substrate on the adhesive layer of the polarizing film, and a second step of forming a second adhesive layer on a coating layer surface removed off from the transfer substrate while removing off the transfer substrate from the coating layer laminated on said polarizing film, wherein a water contact angle of the coating layer surface after the transfer substrate is removed off, increases not more than 15° from a water contact angle of the opposite surface when the coating layer is formed.
