Zusammenfassung:	Provided is an optical laminate suitable for use in an image display device that may be exposed to a high temperature environment. The optical laminate provided comprises: an adhesive sheet that is formed of a photocurable composition which contains a monomer group and/or a partially polymerized product of the monomer group; and a phase difference film. The adhesive sheet and the phase difference film are in direct contact with each other or sandwich therebetween a layer having a thickness of not more than 10 [mu]m. The amount of residual monomer contained in the adhesive sheet is not more than 16,000 ppm (weight basis).
