A '''3D display''' is a [[display device]] capable of conveying [[depth perception|depth]] to the viewer. Many 3D displays are [[stereoscopic]] displays, which produce a basic 3D effect by means of [[stereopsis]], but can cause eye strain and visual fatigue. Newer 3D displays such as [[holographic display|holographic]] and [[light field display]]s produce a more realistic 3D effect by combining stereopsis and accurate [[focal length]] for the displayed content. Newer 3D displays in this manner cause less visual fatigue than classical stereoscopic displays.

As of 2021, the most common type of 3D display is a [[stereoscopy|stereoscopic display]], which is the type of display used in almost all [[virtual reality]] equipment. 3D displays can be near-eye displays like in VR headsets, or they can be in a device further away from the eyes like a 3D-enabled mobile device or [[3D film|3D movie theater]].

The term "3D display" can also be used to refer to a volumetric display which may generate content that can be viewed from all angles.
