Abstract:
A spatial light modulation device includes: a light modulation unit which modulates light according to an image signal; and a first electrode and a second electrode provided on a surface of one of an optical element disposed either on the entrance side of the light modulation unit or the exit side of the light modulation unit and the light modulation unit. Voltage is applied to the first electrodes and the second electrodes.
