1. A stereoscopic image display device comprising:

  • a display displaying side by side a plurality of small images, each of the small images containing three-dimensional display data, to convert the three-dimensional display data into rays and output the rays from each of the small images;

    a first mechanical shutter panel being disposed so as to abut on the front of the display or being integrated with the display so as to be disposed on the front of the display, the first mechanical shutter panel having first micro mechanical shutters therein, each of the first micro mechanical shutters having a same size as each of pixels of the display, the first micro mechanical shutters being arranged in accord with disposition of the pixels of the display;

    a second mechanical shutter panel being disposed in front of the first mechanical shutter panel with a predetermined distance therebetween, the second mechanical shutter panel having second micro mechanical shutters therein, each of the second micro mechanical shutters having the same size as each of the pixels of the display, the second micro mechanical shutters being arranged in accord with the disposition of the pixels of the display,wherein the first mechanical shutter panel makes the first micro mechanical shutters, which are located within a range corresponding to a displaying range of one of a plurality of partial regions provided in each of the small images displayed on the display, serve as one of first mechanical shutters, and the first mechanical shutters each turn on and off in a time-division manner with respect to a corresponding one of the small images, extract the rays in a time-division manner as partial rays each output from the plurality of partial regions, and transmit the partial rays forward,wherein the second mechanical shutter panel makes the second micro mechanical shutters, which correspond to a position of each of the small images displayed on the display, serve as one of second mechanical shutters, and each of the second mechanical shutters becomes on-time when at least one of the first mechanical shutters, which correspond to positions of the partial regions sequentially selected from the plurality of partial regions provided in a corresponding one of the small images, is on-time, and the second mechanical shutters transmit forward the partial rays extracted in a time-division manner per each of the small images, reconstruct the partial rays as the rays, and converge each of the reconstructed rays in front to form a three-dimensional image.
