An object of the present invention is to provide an optical laminate which includes a reflective polarizer, an absorptive polarizer, and at least one adhesive layer, and exhibits high image sharpness in a case of being bonded to a lens or the like of a virtual reality display apparatus. The optical laminate of the present invention includes a reflective polarizer, an absorptive polarizer, and at least one adhesive layer, in which, in a case where the reflective polarizer is heated for 1 minute at a temperature higher than a glass transition temperature of the reflective polarizer by 20° C., the reflective polarizer exhibits a dimensional change of a contraction of 0% or more and less than 0.8% in at least one in-plane orientation, and the reflective polarizer is a reflective linear polarizer formed by alternately laminating two or more different types of birefringent layers.
