Claim 8:
9. A light control sheet, comprising:
a first transparent electrode layer that receives a voltage;
a second transparent electrode layer;
a light control layer including a resin layer formed between the first transparent electrode layer and the second transparent electrode layer such that the resin layer has a plurality of holes and includes a liquid crystal composition including liquid crystal molecules in the plurality of holes; and
an alignment layer formed between the first transparent electrode layer and the light control layer such that a haze of the light control layer is increased in response to application of the voltage to the first transparent electrode layer,
wherein the light control layer is formed such that a minimum size of the holes is 1.0 μm or more and that a maximum size of the holes is 2.5 μm or less, and the light control layer has a central portion of a thickness of the light control layer such that the central portion is lowest in density in the thickness of the light control layer.
