LAMINATED RETARDATION FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a laminated retardation film suitable for continuous production, which is free from problems such as cracks and fractures and does not cause display unevenness when used in a liquid crystal display device. Specifically disclosed is a laminated retardation film which is a laminate of a positively birefringent resin layer and a negatively birefringent resin layer. The laminated retardation film is characterized in that the negatively birefringent resin layer contains a copolymer having a monomer unit L represented by general formula (1) and an ethylenically unsaturated monomer unit M. general formula (1)
