Abstract:
An optical waveguide plate to be used for a display comprising said optical waveguide plate for introducing light thereinto, and a driving section provided opposingly to one surface of said optical waveguide plate and including a number of actuator elements arranged corresponding to a large number of picture elements, for displaying, on said optical waveguide plate, a picture image corresponding to an image signal by controlling leakage light at a predetermined portion of said optical waveguide plate by controlling displacement action of each of said actuator elements in a direction to make contact or separation with respect to said optical waveguide plate in accordance with an attribute of said image signal to be inputted, wherein:a surface-smoothing material, which has an optical refractive index greater than that of said optical waveguide plate, is formed on at least one surface of a main optical waveguide plate body into which said light from a light source is introduced.
