Abstract
A light modulation layer disposed between a first transparent substrate and a second transparent substrate generates a plurality of first strip-like illumination light beams extending in a direction intersecting with a first end surface of the first or second transparent substrate at a first angle with use of light from a light source, when an electric field for a first mode is applied from an electrode to the light modulation layer. The light modulation layer generates a plurality of second strip-like illumination light beams extending in a direction intersecting with the first end surface at an angle different from the first angle or a direction parallel to the first end surface with use of light from the light source, when an electric field for a second mode is applied from the electrode to the light modulation layer.
