The present invention relates to a variable-transmittance optical laminate with simplified manufacturing processes, a manufacturing method thereof, a smart window including the same, and an automobile using the same. The optical laminate includes polarizing plates stacked on both sides while a liquid crystal layer driven in accordance with an electric field and arranged therebetween. The polarizing plate includes a polarizer and a protective layer formed on at least one side of the polarizer. A transparent conductive layer is formed by directly coming in contact with at least one polarizing plate between the polarizing plates on both sides. The transparent conductive layer includes a pattern area patterned in a prescribed shape and a non-pattern area without a pattern. A refractive index adjustment layer provided between the polarizing plates and the transparent conductive layer is formed across the pattern area and the non-pattern area. The total light transmittance of the optical laminate is changed in accordance with voltage application.

    본 발명은, 전계에 따라 구동되는 액정층을 사이에 두고, 양면에 적층된 편광판을 포함하는 광학 적층체에 있어서, 상기 편광판은 편광자 및 상기 편광자의 적어도 일면 상에 형성된 보호층을 포함하고, 투명 도전층은, 상기 양면의 편광판들 중 적어도 어느 하나의 편광판과 직접 접촉하여 형성되며, 상기 투명 도전층은, 소정의 형상으로 패터닝 된 패턴 영역과, 패턴이 형성되어 있지 않은 비패턴 영역을 포함하며, 상기 편광판과 투명 도전층 사이에 구비되는 굴절률 조절층은, 상기 패턴 영역 및 비패턴 영역 상에 걸쳐 형성되며, 상기 광학 적층체는 전압 인가에 따라 전광선 투과율이 변화되는, 투과율 가변 광학 적층체 및 이의 제조방법과, 이를 포함하는 스마트 윈도우 및 이를 적용한 자동차에 관한 것이다.
