A method for applying a voltage to a photo-addressable type display element includes: switching between +V volt and -V volt by a switching circuit to synthesize a rectangular wave pulse of ±V volt; and applying the rectangular wave pulse of ±V volt to the photo-addressable type display element as a bias voltage. When the rectangular wave pulse is to be switched from one of +V volt and -V volt to the other, (i) the rectangular wave is grounded in the course of the switching from the one of +V volt and -V volt to the other, (ii) an output voltage of an output converter, which is not selected after the switching of the rectangular pulse, is changed to about 0 volt, and then, (iii) the rectangular wave pulse is changed to the other of +V volt and -V volt.
