A '''3D display''' is a type of [[display]] that can show different optical depth at the same time. It does so using [[depth cue]]s based largely on focus and/or [[stereopsis]].

3D displays can be world-fixed, like mounted on a desk, or they can be head fixed, like built into a VR headset.

To get a 3D display to show proper [[accommodation]] cues AKA focus, there are multiple ways. The two main ways are [[holographic display]]s and [[light field display]]s. A light field display sends focal stacks of images based on [[ray]]s to the eye.
