A polarizing plate includes: a bonding layer; a polarizer on a first surface of the bonding layer; and a polarizer protective film on a second surface of the bonding layer, and a ratio (β1/α3) of a measured tensile modulus (β1), in a transverse direction (TD), of the polarizing plate to a sum (α3) of a measured thickness (α1) of the polarizer and a measured thickness (α2) of the polarizer protective film is greater than 0.27 and less than 0.50, and a ratio (β2/β3) of a measured tensile modulus (β2), in the TD, of the polarizer to a measured tensile modulus (β3), in the TD, of the polarizer protective film is greater than 0 and less than 0.2.
