Abstract: PURPOSE:To obtain a compact and reliable plane display by directly performing the mechanical deflection of light from a light source on a video output surface. CONSTITUTION:On the video output surface, light sources 2 of R, G and B, a light waveguide 3, a light deflection part 4 by a microactuator are arranged at positions corresponding to the screen picture element on a substrate 1. At a position corresponding to the on-state (lightness is high) of video information, the light is reflected frontward by a mirror 5 and scattered by a light scattering part 7. The light scattering part 7 is arranged in order to widen the angle of visibility from the front surface. Then, the mirror 5 is driven by an electrode 6 for electrostatic driving. Namely, by setting a mirror part and an electrode part at the same potential, the electrode 6 and the mirror 5 receive repulsive force and the mirror 5 rises. On the contrary, the mirror 5 tilts by applying a potential difference. Thus, the light is deflected. Therefore, the mechanical deflection of the light is directly performed on the video output surface, thereby, substantial space for projection becomes unnecessary, the device is miniaturized, the temperature of the device is prevented from getting high, and the reliability of the device is secured.
