International ClassG02B 26/00AbstractAn optical modulator is provided which can be manufactured by means of a simple process, and a display device, and a method of manufacturing same. The optical modulator comprises a first substrate having a movable reflective film that oscillates in accordance with the application of an electrostatic force; a light-transmitting second substrate disposed so as to oppose the first substrate and formed with a transparent electrode for applying the electrostatic force, in a position corresponding to the movable reflective film; and a cavity section, demarcated by the first substrate and the second substrate, for restricting the range of oscillation of the movable reflective film. By forming a movable reflective film by a portion of the substrate and determining the range of oscillation of the movable reflective film by the interval between the substrates, an optical modulator of high durability and high precision can be obtained.Field of SearchBy changing physical characteristics (e.g., shape, size or contours) of an optical elementShape or contour of light control surface altered Light control surface forms image on projected light beam Electro-optic Semiconductor By moving a reflective element Reflective element moved by deformable support Dielectric optical waveguide type OPTICAL MODULATOR Having multiple electrodes Light wave directional modulation (e.g., deflection or scanning is representative of the modulating signal) COMPOSITE PROJECTED IMAGE Multicolor picture LIGHT SHIELD, MASK, HOOD, OR DIAPHRAGM REFLECTOR Plural | |
