    摘要： There is provided an optical scanning element, which has a large scan angle, is quickly responsive, and can be downsized. An optical scanning element according to an embodiment of the present invention includes: a first light-deflecting unit for emitting light to a first area; and a second light-deflecting unit for emitting the light that has been emitted to the first area to a second area wider than the first area. The first light-deflecting unit is configured to be changed in refractive index by a change in applied voltage, and to adjust the first area through the change in refractive index, and the second light-deflecting unit is configured to adjust the second area through diffraction.
