1. A three-dimensional display device, comprising:
a display panel comprising an active area for display of an image mixture comprising a first image and a second image which exhibits parallax with respect to the first image, the active area comprising a plurality of subpixels;
an optical element configured to define a light beam direction of image light emitted from the active area; and
a controller configured to:
acquire a position of a first eye of a user and a position of a second eye of the user, the second eye differing from the first eye; and
drive the active area to display the image mixture based on the position of the first eye and the position of the second eye,
the controller being further configured to:
determine a first visible region within the active area, for emitting image light which propagates to the position of the first eye,
determine a second visible region within the active area, for emitting image light which propagates to the position of the second eye,
determine, from among the plurality of subpixels, a first subpixel which is at least partially included in the first visible region,
determine, from among the plurality of subpixels, a second subpixel which is at least partially included in the second visible region, and
drive a third subpixel which is the first subpixel and also is the second subpixel, to display a third image, the third image being either only the first image or only the second image.
