The present invention provides a variable light transmittance optical laminate, a method for manufacturing the same, and a smart window including the same, the variable light transmittance optical laminate including: a first laminate in which a first polarizing plate including a first functional coating layer, a first transparent conductive layer, and a first alignment film are laminated in this order; a second laminate in which a second polarizing plate, a second transparent conductive layer, and a second alignment film are laminated in this order, said second polarizing plate comprising a second functional coating layer and facing the first laminate; and a liquid crystal layer disposed between the first laminate and the second laminate, in which the liquid crystal layer includes a spherical spacer that is present so as to form a recessed portion in at least one of the first alignment film and the second alignment film, the spherical spacer having a diameter of 4 to 10 [mu] m, and the spherical spacer having a diameter of 1 to 10 [mu] m. At least one of the first transparent conductive layer and the second transparent conductive layer is formed so as to be in direct contact with one of the first polarizing plate and the second polarizing plate, the Vickers hardness of each of the first functional coating layer and the second functional coating layer is 18-41, and the diameter (d; the number (A) of spherical spacers per unit area (1 mm2) satisfies a predetermined relationship ([mu] m).

    本发明提供光透过率可变光学层叠体及其制造方法和包含其的智能窗,上述透过率可变光学层叠体包含:第一层叠体,其是包含第一功能性涂层的第一偏光板、第一透明导电层和第一取向膜依次层叠而成的;第二层叠体,其是与上述第一层叠体相对且包含第二功能性涂层的第二偏光板、第二透明导电层和第二取向膜依次层叠而成的;以及液晶层,其配置在上述第一层叠体和第二层叠体之间的,其中,上述液晶层包含以在第一取向膜和第二取向膜中的至少任一个取向膜上形成凹陷部的方式存在的球状间隔物,上述球状间隔物的直径为4至10μm,上述第一透明导电层和第二透明导电层中的至少一个透明导电层形成为与上述第一偏光板和第二偏光板中的某一个偏光板直接接触,上述第一功能性涂层和第二功能性涂层的维氏硬度各自为18至41,相对于球状间隔物的直径(d;μm)的每单位面积(1mm2)的球状间隔物的数量(A)满足预定的关系。
