Abstract
A method of producing a light control sheet includes forming a multilayer laminate in which a light control layer comprising a liquid crystal composition is sandwiched between a first transparent conductive layer formed on a first transparent support layer and a second transparent conductive layer formed on a second transparent support layer, and conducting laser irradiation to the multilayer laminate such that a laser beam penetrates one of the first and second transparent support layers located closer to a laser source than the first transparent conductive layer, and that an insulating portion is formed in the first transparent conductive layer.

A light control sheet, comprising:
- a light control layer comprising a liquid crystal composition;
- a pair of transparent electrode layers including a first transparent electrode layer and a second transparent electrode layer, and sandwiching the light control layer;
- and
- a pair of transparent support layers sandwiching the light control layer and the pair of transparent electrode layers and comprising a first transparent support layer and a second transparent support layer,
- wherein the first transparent electrode layer is formed on the first transparent support layer and includes a plurality of electrode portions and an insulating portion comprising a structure formed by laser irradiation such that the electrode portions are separated by the insulating portion.
