Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical laminate having an electrically conductive layer formed directly on a retardation layer, which is very thin, has an excellent antireflection function and achieves excellent display characteristics even when applied to a curved part of an image display device.SOLUTION: The optical laminate of the present invention includes a polarizer, a retardation layer bonded to the polarizer, and an electrically conductive layer formed directly on the retardation layer. The retardation layer has an in-plane retardation Rd(550) of 100 nm to 180 nm, satisfying a relationship of Re(450)
