Abstract:
A light source device has a transparent/scattering state switching element for switching the range of irradiation angles, and liquid crystal molecules and dichroic dye molecules are dispersed in a polymer matrix in the PDLC layer of the transparent/scattering state switching element. The range of irradiation angles can thereby be switched, and the color can be prevented from changing when the radiation angle is switched.
