摘要:
An object of present invention is to provide an optical laminate that can be used for a reflective circular polarizer with little occurrence of a ghost in a case of being used in a virtual reality display device, an electronic finder, or the like; a laminated optical film including the reflective circular polarizer; an optical article including the optical laminate; and a virtual reality display device including the optical article. The optical laminate of the present invention includes two or more laminated reflective layers, in which the laminated reflective layer includes one reflective layer A that includes at least one or more cholesteric liquid crystal layers formed of a first liquid crystal compound which substantially consists of a rod-like liquid crystal compound and that does not include a cholesteric liquid crystal layer formed of a second liquid crystal compound which substantially consists of a disk-like liquid crystal compound, and one reflective layer B that includes at least one or more cholesteric liquid crystal layers formed of the second liquid crystal compound which substantially consists of a disk-like liquid crystal compound and that does not include a cholesteric liquid crystal layer formed of the first liquid crystal compound which substantially consists of a rod-like liquid crystal compound, and predetermined requirements are satisfied.
