Document Type and Number:
WIPO Patent Application WO/2023/239100
Kind Code:
A1
Abstract:
The present invention relates to a variable transmittance optical laminate comprising: a first transparent member; a first laminate which is formed on the first transparent member, and on which a first polarizing plate, a first transparent conductive layer, and a first alignment layer are sequentially stacked; a second transparent member facing the first transparent member; a second laminate which is formed on the second transparent member, and on which a second polarizing plate, a second transparent conductive layer, and a second alignment layer are sequentially stacked; and a liquid crystal layer disposed between the first laminate and the second laminate. At least one 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, the first transparent member and the first polarizing plate are bonded by means of a first bonding layer, the second transparent member and the second polarizing plate are bonded by means of a second bonding layer, and at least one of the first bonding layer and the second bonding layer is formed of an adhesive.
