Abstract

A light control sheet includes a light control layer that contains a liquid crystal compound and a dichroic dye, and a first transparent electrode layer and a second transparent electrode layer that are a pair of transparent electrode layers sandwiching the light control layer. As viewed perpendicular to a surface of the light control sheet, the first transparent electrode layer includes a non-conductive portion extending linearly and a conductive portion divided by the non-conductive portion, and a portion of the second transparent electrode layer that is conductive overlaps with each of the conductive portion and the non-conductive portion. An average transmittance for light in an infrared range of the light control sheet in an opaque state is 64% or less.
