Polyethylene terephthalate-based resin film, and polarizer, transparent conductive film, touch panel, and image display device using same

Abstract

An object is to provide a polyethylene terephthalate-based resin film that has excellent processing suitability and that particularly can effectively suppress the occurrence of cleavage in the film layer of a portion cut with a knife. Another object is to provide a polarizer, a transparent conductive film, a touch panel, and image display devices such as a liquid crystal display device and an organic EL display device, all of which use the polyethylene terephthalate-based resin film. A polyethylene terephthalate-based resin film satisfying the following (1) and (2): (1) the polyethylene terephthalate-based resin film has a retardation of 3000 to 30000 nm; and (2) the polyethylene terephthalate-based resin film has an amorphous orientation parameter of 0.330 or more as measured by an ATR-FTIR method.
