Abstract
An optical system of a display including a light conducting plate introduced with light and a panel portion provided to oppose to one plate surface of the light conducting plate. The panel portion includes a driving part arranged with actuator parts each corresponding to a plurality of pixels so as to control displacement motions of the actuator parts in the contacting and separating directions to and from the light conducting plate correspondingly to attributions of input image signals, thereby controlling leaked light-beams in predetermined regions of the light conducting plate, to thereby cause the light conducting plate to display an image corresponding to the input image.
