摘要： Mediums that are arranged opposite to an elemental-image display unit, that form two lens arrays having different principal planes together with substrates, and that switches a polarization direction of incident light corresponding to applied voltage, thereby making lens effect of either one of the lens arrays effective are included. By controlling the polarization direction synchronizing with a display timing of images to be displayed on the elemental-image display unit, the lens array to be effective is switched at each display timing, and images having different near or far direction are alternately displayed on the elemental-image display unit.

摘要： A three-dimensional display apparatus is provided with an optical element including optical apertures arranged opposite a display module and in association with the parallax images. The optical apertures cause the parallax images to be displayed in a near-side region closer to an observer, while causing a three-dimensional image to be displayed in a far-side region located opposite the observer with respect to the display module. When a smooth three-dimensional image is to be displayed in the near-side region, the optical gap between the optical element and the display surface is set longer than a reference distance depending on the position of the three-dimensional image. In order to display a smooth three-dimensional image in the far-side region, the observer sets the optical gap shorter than the reference distance depending on the position of the three-dimensional image.
