[PROBLEMS] To use a polarizing plate that does not cause deterioration in optical characteristics, particularly transmittance, even when exposed to a high-temperature environment, and that can sufficiently withstand use in a high-temperature environment, and the polarizing plate. A laminated optical member and a liquid crystal display device are provided. A polarizing plate in which a protective film is laminated on both sides of a polarizing film made of a polyvinyl alcohol resin film in which a dichroic dye is adsorbed and oriented, and at least one of the protective films is made of a propylene resin film. That is, the propylene-based resin film has a xylene-soluble component at 20 ° C. of 1% by weight or less, and a laminated optical member and a liquid crystal display device using the same.
