Abstract: A light control laminate includes a light control sheet; and an adhesive layer that adheres a rear surface of the light control sheet to a transparent body by self-adhesion, the light control laminate being provided with a sealing part that adheres an edge face of the light control sheet to the transparent body, the sealing part being used for sealing the edge face of the light control sheet. The light control sheet includes a first hard coat layer that constitutes a front surface of the light control sheet, and a second hard coat layer that constitutes the rear surface of the light control sheet, by which separation and re-adhesion of the light control sheet are facilitated, while suppressing misalignment of the light control sheet with respect to the transparent body.

Abstract: A light control sheet includes two transparent substrate layers each including an electrode layer, and a light control layer formed between the two transparent substrate layers. The light control layer includes a transparent resin layer defining a void, a liquid crystal composition filling the void, and a spacer that determines a thickness of the light control layer. Each transparent substrate layer in the light control sheet has external haze of less than 0.1%, and each transparent substrate layer in the light control sheet has internal haze of 0.1% or more and 2.0% or less.
