The present invention provides an optical layered body comprising, in order, a protective film, a polarizing plate, a retardation layer of one or more layers, and an adhesive layer, wherein the protective film satisfies the following formula: first modulus of elasticity - second modulus of elasticity ≧300MPa.nn n n In the formula, the first modulus of elasticity is a tensile modulus in a direction orthogonal to the absorption axis of the polarizing plate at a temperature of 23 ° C and a relative humidity of 55% RH, and the second modulus of elasticity is at a temperature of 23 ° C and relative. The tensile modulus of elasticity in a direction parallel to the absorption axis of the polarizing plate at a humidity of 55% RH. |
