A '''3D display''' is a theoretical type of display that can show a completely natural 3D scene. It does this by using focal cues, which are depth cues that use the individual focus of each eye. 3D displays work by showing different parts of an image at different focal depths, all at the same time. This can be generated using [[holographic display]]s and [[light field display]]s.

3D displays connected to a computer system can enable a 3D human-computer interaction loop, which can be used in 3D software for design. A 3D display shows [[depth cue]]s based largely on focus and/or [[binocular disparity]].
