  • Patent number: 9958742
    Abstract: The present application relates to an optical element. The exemplary optical element may have a variable transmittance by whether an external signal is applied or not. Also, since the optical element may apply the external signal by using a composite layer having a low transmittance to light in an infrared region, the optical element may block heat, and save energy. Such an optical element may be usefully employed in various optical devices, for example, a sunroof.
