There is provided a polarizing plate including a first protective film, a polarizer, and a second protective film in this order, in which the first protective film is a film including a synthetic polymer, and has a thickness of 30 μm or less, an elastic modulus in the TD direction of 2 GPa to 2.5 GPa, and a humidity dimensional change rate in a TD direction of 0.1% or less, and the second protective film has an evaluation value represented by the following Equation (2) of 7.0 to 11.0: Evaluation value=elastic modulus (GPa) of the second protective film in a TD direction/humidity dimensional change rate (%) of the second protective film in the TD direction×(thickness (μm) of the second protective film/thickness (μm) of the first protective film)2×(30/thickness (μm) of the polarizer)1/2 Equation (2).
