Abstract:
There is provided a light modulating element including a plurality of compounds whose light absorption characteristics change with external simulation. The plurality of compounds are compounds having different absorption wavelengths. The light modulating element has a variable transmittance VT(λ) obtained by combining light absorption characteristics of the plurality of compounds. NWDMax
