Document Type and Number:
WIPO Patent Application WO/2023/027390
Kind Code:
A1
Abstract:
The present invention relates to a transmittance-variable optical laminate and a manufacturing method therefor, a smart window comprising same, and a vehicle and a building window or door employing same, the optical laminate comprising: a first polarizing plate; a first transparent conductive layer formed on one surface of the first polarizing plate; a second polarizing plate opposite to the first polarizing plate; a second transparent conductive layer formed on one surface of the second polarizing plate and opposite to 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 of the first transparent conductive layer and the second transparent conductive layer is formed to come into direct contact with one of the first polarizing plate and the second polarizing plate, and at least one of the first polarizing plate and the second polarizing plate comprises a reflective polarizing plate.
