摘要： An object of the present invention is to provide a laminated optical film including a reflective circular polarizer with high image sharpness of a reflected image, and an image display device formed of the laminated optical film. The object is achieved by providing the laminated optical film including at least a reflective circular polarizer, a retardation layer that converts circularly polarized light into linearly polarized light, and a linear polarizer in this order, in which a surface of the reflective circular polarizer on a side opposite to the linear polarizer has a surface roughness Ra of 100 nm or less.

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.

摘要： An object is to provide an optical system capable of improving the brightness of a main image while eliminating a ghost image. In an optical system including: an image display device that emits an image; a linear polarizer through which light associated with the image passes; a first quarter wavelength plate which receives the light from the linear polarizer; a half mirror; a reflective polarizer; and a second quarter wavelength plate provided between the reflective polarizer and the half mirror, retardance of the first quarter wavelength plate and retardance of the second quarter wavelength plate are equal, and thus the object is achieved.
