The present invention relates to a transmittance variable optical laminate and a manufacturing method thereof, a smart window including the same, and doors and windows for automobiles or buildings applying the same. The transmittance variable optical laminate comprises: a first polarizing plate; a first transparent conductive layer formed on one surface of the first polarizing plate; a second polarizing plate facing the first polarizing plate; a second transparent conductive layer formed on one surface of the second polarizing plate and facing the first transparent conductive layer; and a liquid crystal layer provided between the first transparent conductive layer and the second transparent conductive layer. At least one transparent conductive layer of the first transparent conductive layer and the second transparent conductive layer is formed to directly contact any one polarizing plate of the first polarizing plate and the second polarizing plate, and the transmittance variable optical laminate has at least one side surface having a surface roughness value between 15-60 ㎛. According to the present invention, it is possible to provide a transmittance variable optical laminate having a simplified manufacturing process by not including an additional member for forming a conductive layer.
