PURPOSE:To realize driving by low power, and to increase intensity of output light, by providing an electrode group like an array, on a plate of a ferroelectric substance having an electro-optical effect, and pinch-holding the plate by a reflecting member having a Dach type reflecting surface, and a polarizer. CONSTITUTION:Light which is made incident to an optical shutter array consisting of a plate 50, a polarizer 60 and a reflecting member 70 is made incident from the upper direction of the polarizer 60, becomes linear polarized light, is made incident to the plate 50 from an incident part H, is emitted from an emitting part I, is reflected by a Dach type reflecting surface of the reflecting member 70, is made incident to the plate 50 again in an incident part J, transmits it, and is emitted from an emitting part K. To this emitted light, the polarizer 60 operates as an analyzer. On electrode groups 52, 53, a common electrode 51 is provided, both electrode groups 52, 53 are driven by a common switching signal, a phase difference is generated as addition, and an electro-optical effect generating area in the transmitting direction of light is increased substantially. |
