摘要： An optical modulation device is constituted by a polarizer; a first film forming a first state and a second state depending on an electric field applied thereto, the first state causing birefringence and the second state not causing birefringence respectively of polarized light from the polarizer, the first film having a thickness set for functioning as a halfwave plate in its first state; and a second film not causing birefringence of light having passed through the second state of the first film but causing birefringence of light having passed through the first state of the first film, the second film having a thickness set for functioning as quarter wave plate or a halfwave plate when the first film is set in its first state. The light from the second film is caused to enter the second film again through a reflection means or a third film selectively forming a first state causing birefringence of light which has caused birefringence and passed through the second film or a second state not causing birefringence of light which has passed through the second film without causing birefringence. The light thus modulated is then caused to enter an analyzer. As a result, an optical modulation giving a large contrast is provided by using a material having a small birefringence effect for the first film or third film.
