<p><P>PROBLEM TO BE SOLVED: To provide a stereoscopic image display device which pseudo stereoscopically displays a two dimensional image without deteriorating the light use efficiency, and less affecting the visibility by a rotation angle. <P>SOLUTION: A stereoscopic image display device comprises a shutter for a right eye and a shutter for a left eye, the shutters having electrochromic elements respectively having polarization axes. The electrochromic element includes stereoscopic image visibility glasses for transmitting at a time of no voltage application only a linear polarized light in a predetermined polarization direction, and transmitting at a time of voltage application all polarized lights, and a three dimensional image generation circuit for generating a three dimensional image from a two dimensional image, a two dimensional image display device generating a linear polarized light perpendicular to the polarization axis for alternately displaying in chronological order an image for a right eye and an image for a left eye, and a control circuit for matching a timing of voltage application on each electrochromic element provided in the shutter for a right eye and the shutter for a left eye with a timing for displaying the image for a right eye and the image for a left eye. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
