[Problem] To provide a polarizing element exhibiting high polarization performance in relation to a light source having a maximum light emission intensity at a wavelength of 520-545 nm, and a polarizing plate. [Solution] A polarizing element is characterized by including a dichroic dye represented by formula (1) and formula (2), and comprising a stretched polyvinyl alcohol film. (In formula (1), n is an integer of 1-4.) (In compound (2), X is a phenyl group or a naphthyl group having at least one sulfo group, R1-R6 each independently represent a hydrogen atom, a lower alkyl group having 1-4 carbon atoms, an alkoxyl group having 1-4 carbon atoms, or an acetylamino group, Y represents a hydrogen atom or an amino group, and m represents 0 or 1.) |
