Display device, position adjustment pattern display program, recording medium, polarized glasses, and method of adjusting position of filter of the display device
First Claim
1. A display device comprising:
- an image display section for displaying image information at a first segment and a second segment; and
a divided wavelength plate filter for rotating polarized light from the image information at the first segment in a direction that is different from the direction of polarized light from the image information at the second segment, the divided wavelength plate filter being rotationally adjustable in a plane that is parallel to a display surface of the image display section;
wherein the display device displays a position adjustment pattern having at least one of colors, figures, characters, symbols, diagrams, and designs, the position adjustment pattern varying to a viewer depending upon the relative positions of the image display section and the divided wavelength plate filter when the divided wavelength plate filter is adjusted.

Abstract
Even if a divided wavelength plate filter is mounted, it is possible to reliably display a three-dimensional image or perform a displaying operation on from one screen to a plurality of screens. In a display device, the relative positions of an image display section and a divided wavelength plate filter for rotating polarized light from image information at a first segment in a direction that is different from the direction of polarized light from image information at a second segment can be adjusted. At the time of positional adjustment, the display device displays a position adjustment pattern (112) having colors, figures, characters, symbols, diagrams, or designs, or combinations thereof which differ from each other depending on the segment.
