Claim Text:
1. A polarizing plate, comprising: a polarizing film having a thickness of 10 μm or less; and a protective layer provided on at least one side of the polarizing film through intermediation of an adhesion layer, wherein the adhesion layer has a thickness of 0.7 μm or more, wherein the adhesion layer has a percentage of bulk water absorption of 10 wt % or less, and wherein the polarizing film has a value for Aa×(Is/Ia) of 0.53 or more, where: the Aa represents an absorbance of the polarizing film in an absorption axis direction thereof at a wavelength of 480 nm; the Ia represents a value obtained by integrating an integrated intensity distribution of an integrated intensity in a thickness direction of the polarizing film in an entire interval in the thickness direction of the polarizing film, the integrated intensity being obtained by integrating a Raman spectrum of the polarizing film in a wavenumber interval from 90 cm the Is represents a value obtained by integrating an integrated intensity distribution of an integrated intensity in the thickness direction of the polarizing film in the entire interval in the thickness direction of the polarizing film, the integrated intensity being obtained by integrating Raman scattering of I
