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 plate 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 rigid transparent plate is laminated to at least one surface of a main optical waveguide plate body into which said light from a light source is introduced, via a joining layer which has substantially the same optical refractive index as that of said optical waveguide plate.
