Abstract
A laminate having improved polarization characteristics, in which an adhesive layer is formed on one surface of a polarizing film, a retarded polarizing film or a retardation film and a release film having a transparent biaxially oriented aromatic polyester film as a base film is formed on the surface of the adhesive layer, said laminate being situated such that (1) a direction of an orientation main axis, as measured by a microwave transmission-type molecular orientation meter, of the biaxially oriented aromatic polyester film in the release film and (2) a direction of an orientation axis of the polarizing film, the retarded polarizing film or the retardation film are substantially the same or substantially form an angle of 90.degree.. The laminate of this invention makes it easy to find foreign matter or defects by the visual inspection of the polarizing film, the retarded polarizing film or the retardation film of a large-sized TFT system or STN system.
