Abstract: A polarizing plate includes an outer protective film and a polarizer. The sum S of the product of the modulus of elasticity and the cube of the thickness in each layer is up to 150,000 Pa·mm3, and the value obtained by dividing the sum S by the Knoop hardness k of the outer protective film is 200 or more but up to 450. The polarizing plate is excellent in surface pencil hardness even when its thickness is reduced.
