POLYESTER FILM FOR RELEASE FILM FOR POLARIZING PLATE, AND LAMINATE HAVING IMPROVED POLARIZATION CHARACTERISTICS

摘要

The present invention provides a polyester film suitable as a base film in a release film which is capable of realizing a high inspection accuracy when a polarizing plate laminated with the release film is subjected to visual inspection using a Cross-Nicol method for detecting defects such as distortion and unevenness or inclusion of foreign matters therein. The polyester film for a release film for a polarizing plate according to the present invention has a haze of 7 to 18% and an L value of not more than 77 as measured by a reflection method.
