Abstract
A three-dimensional display device includes a display panel, a shutter panel, an obtainer, and a controller. The display panel includes a plurality of subpixels that display a parallax image. The parallax image includes a first image and a second image having parallax between the images. The shutter panel defines a ray direction of image light from the parallax image. The image light is emitted from the display panel. The obtainer obtains an ambient illuminance level around an image viewed by a user. The controller determines a pupil diameter of the user based on the ambient illuminance level. The controller controls at least one of the display panel or the shutter panel based on the pupil diameter.
