Claim 0:
1. A light control sheet, comprising:
a first transparent electrode layer that receives a voltage;
a second transparent electrode layer;
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; and
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,
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 includes a high-density portion and a low-density portion such that the high-density portion is in contact with the alignment layer and includes the liquid crystal composition at a density higher than a density of the liquid crystal composition in the low-density portion per unit thickness of the light control layer.
