Abstract: Second barrier electrodes are arranged under first barrier electrodes so as to fill gaps between the first barrier electrodes, while an insulating layer is located between the first barrier electrodes and the second barrier electrodes. The number of first barrier electrodes and the number of second barrier electrodes in each barrier pitch are 6 or more. The positions of the barriers formed by the first barrier electrodes and the second barrier electrodes are controlled by the reception of a signal representing detected positions of the eyes of a viewer. If pitches of the first barrier electrodes are defined as BE, and the widths of regions in which the first barrier electrodes are overlapped with the second barrier electrodes are defined as BA, a ratio BA/BE of the widths BA to the pitches BE are 0.3 or smaller. This configuration can suppress the occurrence of moire.

Abstract: A stereoscopic display apparatus comprising: a display element, a liquid crystal lens being set in front of the display element. The liquid crystal lens comprises a first electrode made of a plane-like transparent electrode, and a second electrode having plural comb-like transparent electrodes, a liquid crystal layer is held between the first electrode and the second electrode. A pitch of the liquid crystal lens is changed, by changing the pattern of voltage to be applied to the comb-like transparent electrodes, an individual voltage according to the pattern of voltage is applied to each of the plural comb-like transparent electrodes, the pitch of the liquid crystal lens is changed depending on a position of an observer with respect to the stereoscopic display panel, in front/back direction. Thus, the stereoscopic display apparatus can provide proper images even as a viewer moves in the front/back direction with respect to the stereoscopic display panel.
