The disclosure relates to a transmittance variable optical laminate, a manufacturing method therefor, a smart window including the same, and a vehicle to which the same is applied. The transmittance variable optical laminate includes a first polarizing plate including a first transmission axis, a second polarizing plate including a second transmission axis, a first transparent conductive layer provided on one surface of the first polarizing plate, a second transparent conductive layer provided on one surface of the second polarizing plate, and a liquid crystal layer provided between the first transparent conductive layer and the second transparent conductive layer. The liquid crystal layer is driven in a twisted nematic (TN) mode, at least one of the first transparent conductive layer and the second transparent conductive layer is formed in directly contact with the polarizing plate, and a cross angle of the first transmission axis and the second transmission axis is less than or equal to 50°.
