Abstract:
A light control module including a light control sheet and a drive circuit that applies a voltage to a first electrode and a second electrode of the light control sheet. The light control sheet includes a light control layer switchable between a transparent state and an opaque state according to an applied voltage. The light control sheet has a feeding area for applying a voltage to the first and second electrodes. The light control sheet is formed such that when the light control sheet receives a voltage that causes a transmittance of the light control sheet to be equivalent to a Munsell value of 90% in a region closest to the feeding area, the light control sheet has a transmittance equivalent to a Munsell value of 50% in a region farthest from the feeding area, where a Munsell value of 100% is a maximum transmittance of the light control sheet.
