Abstract:
The object of the present invention is to provide a laminate polarizing plate of which application to liquid crystal displays is able to simplify constitutions and production procedures of the displays, and to reduce cost thereof; and to provide an industrially advantageous method of producing the compound polarizing plate, and a liquid crystal display using the same. The object is achieved by a laminate polarizing plate comprising a polarizing film, an adhesive layer and a phase retarder film which being laminated in this order, wherein said phase retarder film comprises at least one coating layer having refractive index anisotropy of which an in-plane retardation value (R0) is 0 to 10 nm and a retardation value in the thickness direction (R′) is 40 to 300 nm, wherein said coating layer is formed on a transfer substrate, followed by being transferred on a surface of the adhesive layer of the polarizing film.
