Abstract
An optical device and a use thereof are provided. The optical device is capable of suppressing external bubble inflow by eliminating negative pressures that can occur due to shape deformation of a base material in an environment changing between a high temperature and a low temperature and generating a positive pressure. Such optical device can be used as various transmittance-variable devices.
