Abstract

A three-dimensional display unit has a liquid crystal panel for simultaneously displaying a plurality of different parallax images and an optical characteristic variable lens attached to the liquid crystal panel. The optical characteristic variable lens is formed by an array of cylindrical lenses such that a transparent substance having high flexibility is supported by transparent electrodes from both substance sides and optical characteristics of each of the cylindrical lenses can be changed by applying a voltage to the transparent substance to change at least one surface shape of the transparent substance. The three-dimensional display unit may have a head detecting section for detecting a spatial position of an observer's head; and a control section connected to the head detecting section and controlling an operation of the optical characteristic variable lens based on position information of the observer's head detected by the head detecting section such that a stereoscopic image is regenerated in an optimum position of the observer's head. Another three-dimensional display unit is also shown.
