Abstract: Provided is an image display device including an optical laminate having, in order, a pressure-sensitive adhesive layer, a specific laminate including an alignment layer and an optically anisotropic layer which are adjacent to each other, and another pressure-sensitive adhesive layer in this order, in which the pressure-sensitive adhesive layers are adjacent to the two surfaces of the specific laminate. The specific laminate has a thickness of 15 μm or less, the optically anisotropic layer has a thickness of 5 μm or less, and a thickness d of the alignment layer and an elastic modulus E of the alignment layer satisfy Expression (1): −E+0.45×d+3.6>0 (1), where d is in units of μm, and E is in units of GPa.

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.
