PHASE DIFFERENCE PLATE WITH PROTECTIVE FILM, METHOD FOR MANUFACTURE THEREOF, PRESSURE-SENSITIVE ADHESION TYPE PHASE DIFFERENCE PLATE WITH PROTECTIVE FILM AND PRESSURE-SENSITIVE ADHESION TYPE OPTICAL MATERIAL WITH PROTECTIVE FILM

摘要

Protective film retardation plate of the present invention, the first protective film in a phase plate, order a base film and of the protective film is at least 2 having a pressure-sensitive adhesive layer bonded on the side, as, joined to a phase difference plate and the first protective film other than the protection film is different from the adhesive strength of each adherend and the adhesive strength of the first protective film is the smallest. This protective film is a retardation plate, it is possible to suppress the occurrence of curl, even if the thin phase retardation plate, a good working Chengdu, also had a good releasability. ; Protective film, retardation plate, the pressure-sensitive adhesive layer
