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.
