PURPOSE:To obtain a fine stereoscopic video by connecting a support to a liquid crystal display through a movable support part which is vibrated at right angle to an image surface. CONSTITUTION:A low-frequency signal of 50Hz is applied to the voice coil of the liquid crystal display assembly 3. Then the movable part of a back light vibration unit 24 vibrates through a voice coil bobbin 15. Respective fluorescent tubes at a stationary part, on the other hand, are supplied with electric power from outside by electric conductors to illuminate. Pressure is applied to a space 8 as the movable part vibrates and this pressure variation vibrates the liquid crystal display unit 25 at a frequency of 50Hz. This assembly is a passive type provided with the space as mentioned above and a roll edge 9 which excellently moves is provided at the outer peripheral part of the liquid crystal display 7, so the display surface can vibrates in parallel to a relatively large amplitude without torsional association nor divisional vibration. |
