Polarizing plate and organic electroluminescent display device

The present invention addresses the problem of providing a polarizing plate and an organic electroluminescent device, the polarizing plate being capable of protecting a display element from outside light when used in a display device, particularly in an organic EL display device, and improving adhesion between a layer containing a dye compound and an adjacent layer without the display element causing light emission loss. This polarizing plate comprises a hard coat layer, a protective film, a polarizer, and a phase difference film in this order from the viewing side, and is characterized in that the hard coat layer and/or the protective film contains a dye compound that has a maximum absorption wavelength within a range of 360-379 nm in an absorption spectrum in a wavelength region of 300-460 nm, the protective film and/or the phase difference film contains an ultraviolet absorbent, and a layer containing the dye compound is located closer to the viewing side than a layer containing the ultraviolet absorbent.
