Light control device comprising a transparent adhesive layer covering a sheet edge face of a light control sheet and method for producing the same

A light control device, comprising:

• a first transparent coating substrate having a first bonding surface;
• a second transparent coating substrate having a second bonding surface;
• a light control sheet positioned between the first bonding surface of the first transparent coating substrate and the second bonding surface of the second transparent coating substrate;
• and
• a transparent adhesive layer joining the first bonding surface of the first transparent coating substrate and the second bonding surface of the second transparent coating substrate together around the light control sheet,
• wherein the light control sheet includes a first transparent electrode film, a second transparent electrode film, and a liquid crystal layer including a liquid crystal composition such that the liquid crystal composition is filling space between the first transparent electrode film and the second transparent electrode film, the first transparent electrode film includes a first support film and a first electrode layer formed on the first support film joined to the first bonding surface via a first transparent adhesive, the second transparent electrode film includes a second support film and a second electrode layer formed on the second support film joined to the second bonding surface via a second transparent adhesive, the light control sheet has a sheet edge face formed by an edge face of the first electrode layer, an edge face of the second electrode layer, and an edge face of the liquid crystal layer, the first transparent adhesive, the second transparent adhesive, and the transparent adhesive layer include an identical resin as a main component, and the transparent adhesive layer covers the sheet edge face and has a water absorption rate of 2% or less in accordance with a method of JIS K 7209:2000.
