OPTICAL LAMINATE AND MANUFACTURING METHOD THEREFOR, SMART WINDOW COMPRISING SAME, AND DOOR AND WINDOW FOR AUTOMOBILE AND BUILDING USING SAME
The present invention relates to a variable transmittance optical laminate and a manufacturing method therefor, a smart window comprising same, and a door and window for an automobile and a building to which same is applied. The variable transmittance 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, wherein at least one transparent conductive layer of 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, includes a conductive polymer, and has at least one value of 0 to 0.05 among crack density values calculated according to Equation 1 below at a tensile strain of greater than 1% and less than or equal to 10%. [Equation 1] ρ(ε) = ℓ(ε)/A (where ε is tensile strain (%), A is the area of an observation region (mm2), ρ(ε) is a crack density value of the transparent conductive layer calculated at the tensile strain ε, and ℓ(ε) is a crack area of the transparent conductive layer in the observation region A measured at the tensile strain ε (mm2).
