A polarization plate includes a
polarizer having polarization performance; a first protective film bonded to one surface of the
polarizer through an
adhesive layer 1; and a second protective film bonded to the other surface of the
polarizer through an
adhesive layer 2, in which a modulus of elasticity of the first protective film at 25° C. and
relative humidity of 60% in an absorption axis direction of the polarizer is greater than or equal to 1.0 GPa and less than 4.0 GPa, a ratio of the modulus of elasticity of the first protective film at 25° C. and
relative humidity of 60% in the absorption axis direction of the polarizer to a modulus of elasticity of the first protective film at 25° C. and
relative humidity of 60% in a direction orthogonal to the absorption axis of the polarizer is less than or equal to 0.8, a modulus of elasticity of the second protective film at 25° C. and relative
humidity of 60% in the absorption axis direction of the polarizer is greater than or equal to 2.0 GPa and less than 5.0 GPa, and (Expression 1) and (Expression 2) described below are satisfied, suppresses
curling of the polarizer in the absorption axis direction (d1 and d2 are thicknesses of the first protective film and the second protective film (unit: μm)).d2 / d1≦0.8; (Expression 1)d2≦40 μm (Expression 2)
