The present invention relates to a variable transmittance optical laminate and a manufacturing method thereof, and smart windows comprising the same and windows for an automobile or building having the same applied. The variable transmittance optical laminate comprises: a first laminate in which a first polarizing plate, a first transparent conductive layer, and a first alignment layer are sequentially stacked; a second laminate which faces the first laminate and in which a second polarizing plate, a second transparent conductive layer, and a second alignment layer are sequentially stacked; a liquid crystal layer disposed between the first laminate and the second laminate; and a sealant formed along an outer circumferential surface of the liquid crystal layer to seal the liquid crystal layer, wherein at least one transparent conductive layer among the first transparent conductive layer and the second transparent conductive layer is formed in direct contact with any one of the first polarizing plate and the second polarizing plate, and wherein the sealant includes a first region which overlaps in a planar direction with at least one of the first alignment layer and the second alignment layer, and a second region which does not overlap therewith, wherein a width of the first region is 5 to 70 % of the sum of widths of the first region and the second region. According to the variable transmittance optical laminate of the present invention, a manufacturing process can be simplified and a thickness can be significantly reduced.
