1. A three-dimensional display device, comprising:
a display configured to display a parallax image including a right-eye viewing image and a left-eye viewing image;
a barrier configured to define a traveling direction of image light of the parallax image; and
a controller configured to control the display,
wherein the display includes a first area and a second area, the first area and the second area being different from each other in parallax value of the parallax image, and wherein the controller causes a black image not to appear between the right-eye viewing image in the first area having a lower parallax value of the parallax image, and causes the black image to appear between the right-eye viewing image and the left-eye viewing image in the second area having a higher parallax value of the parallax image.
