Abstract
A display device including a display part including a pixel of a first series having a first horizontal pixel width and a pixel of a second series having a second horizontal pixel width smaller than the first horizontal pixel width, the pixels of the first series and the pixels of the second series being arrayed alternately in each of a horizontal direction and a vertical direction, and a light beam control part that controls a light beam from the display part or a light beam toward the display part.
Claims17
A display device, comprising:
- first-series pixels including a first first-series pixel and a second first-series pixel;
- second-series pixels including a first second-series pixel arranged between the first first-series pixel and the second first-series pixel in a first direction;
- and
- a parallax barrier corresponding to the first series pixels and the second series pixels and comprised of a plurality of selectively transmissive barriers including a first barrier, a second barrier, and a third barrier arranged between the first barrier and the second barrier,
- wherein, in a first display mode in which the first first-series pixel is configured to display a first image corresponding to a first viewpoint and the second first-series pixel is configured to display a second image corresponding to a second viewpoint:
- the third barrier is configured to be in a transmissive state;
- the first barrier and the second barrier are configured to be in a non-transmissive state;
- the first image of the first first-series pixel is radiated to the first viewpoint through the third barrier;
- the second image of the second first-series pixel is radiated to the second viewpoint through the third barrier;
- and
- the first second-series pixel is configured to display a black color or a gray color.
