Title: POLARIZING PLATE
Abstract:
The present invention provides a polarizing plate that is improved in durability and that can be used as-is in a state where a polarizing film is layered on a resin substrate. This polarizing plate comprises a polyester resin substrate and a polarizing film that is layered on one side of the polyester resin substrate and that has a thickness of 10 µm or less. The degree of crystallinity of the polyester resin substrate as calculated by attenuated total reflection spectrometry is from 0.55 to 0.80, and the boric acid concentration in the polarizing film is from 10 wt% to 20 wt%.
