PROBLEM TO BE SOLVED: To provide a polarized light image measuring device capable of discriminating an expression tissue from a lesion and obtaining a polarized light image to enable diagnosis about the extent of invasion of an intra-mucosa cancer, and provide a polarized light image measuring and displaying system for displaying the expression tissue to be discriminated.SOLUTION: This polarized light image measuring device includes: a polarized light irradiator for applying a plurality of polarized irradiation light beams to a predetermined region of a living body from the surface layer thereof; an image pickup for imaging the plurality of polarized reflected light beams respectively from the surface layer of the region; and a polarized light transformer for performing the polarized light transformation processing for the plurality of imaged light intensity image information pieces to thereby transform the expression tissue expressed on the surface layer of the region to polarized light characteristic image information depending on a predetermined polarization characteristic for discriminating the expression tissue expressed on the surface layer of the region from the tissue of the surface layer, and obtaining a polarized light characteristic image depending on the polarization characteristic based on the polarized light characteristic image information.
