Abstract: A lighting device that can switch between intensity distributions of emitted light with a simple configuration. The lighting device includes a light source, a polarization controller, and a polarizing plate, in which the polarization controller switches light emitted from the light source between light components having two or more different polarization states to be incident into the polarizing plate, and the polarizing plate functions as a diffraction grating that has two or more regions having different polarization states of transmitted light in an in-plane direction and where one or more regions among the regions are periodically disposed.
