-36. (canceled)
A light modulating device comprising:
- a light transmissive plate having a curved surface, the light transmissive plate including a glass plate;
- and
- a light modulating cell, the light transmissive plate having a higher rigidity than a rigidity of the light modulating cell, the light modulating cell comprising:
- a first laminated body including a first resin substrate;
- a second laminated body including a second resin substrate;
- a liquid crystal layer containing a dichroic dye and being provided between the first laminated body and the second laminated body;
- a sealing member which is provided between the first laminated body and the second laminated body, defines a space for formation of the liquid crystal layer, the sealing member being disposed in a frame shape surrounding the liquid crystal layer;
- a polarizing plate provided at only one of:
- (1) a first side of the liquid crystal layer on which the first laminated body is provided;
- or (2) a second side of the liquid crystal layer on which the second laminated body is provided.
