Patent ID: 7400447

Claim:
A stereoscopic image display device, comprising: an image display means composed of a plurality of pixels arranged in a matrix pixel arrangement, the matrix pixel arrangement being subdivided into a repeating group of pixels in a predetermined order, each pixel in the repeating group of pixels corresponding to one of a plurality of parallax images that together form a stereoscopic image; a horizontal directional control means, which is arranged at a predetermined distance away from the image display means, the horizontal directional control means having one or more aperture portions corresponding to the matrix pixel arrangement formed within a shielding portion, the aperture portions giving a horizontal directivity so that image information light emitted from each pixel forming each parallax image is presented independently to each of different places of observation; a vertical enlarging means, which is arranged in front of the horizontal directional control means in vertical alignment with the matrix pixel arrangement so that the image information light from an aperture of the horizontal directional control means does not superpose, and enlarges a vertical view angle by giving a vertical optical action to the image information light having passed the aperture of the horizontal directional control means; and a cylindrical lens array, which is provided between the image display means and the vertical enlarging means, having a horizontal axis meridian for enlarging the height of an image generated for each pixel of the image display means and projecting the image generated for each pixel of the image display means to the vertical enlarging means.
