LIGHT MODULATING DEVICE

The present application can provide a light modulating device that can stably maintain designed optical properties even after an encapsulation process in which a pressure is applied, such as an autoclave process, an optical device or a manufacturing method thereof. The present application can also provide a light modulating device, which can also stably maintain the orientation state of a light modulation layer while effectively securing adhesive force between upper and lower substrates, an optical device comprising the same or a manufacturing method thereof.
