The present invention relates to a variable transmittance optical laminate and a smart window comprising the same, the variable transmittance optical laminate comprising a dimming laminate, the dimming laminate comprising: 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 which is provided between the first transparent conductive layer and the second transparent conductive layer, and which is provided with a surface protective film and/or a hard coat layer on one or both surfaces of the light-dimming laminate. 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 release force of the surface protective film is 1.0 N/25 mm to 2.4 N/25 mm, and the surface pencil hardness of the hard coat layer is HB to 6H.
