Abstract: An image display unit provided with an image focusing member for focusing an image of a point light source on a pupil of an observer as means for projecting images displayed on a transmission type image display plate, which is capable of following the movement of the observer with a simple construction. A point light source array 12 composed of a large number of point light sources 120 which are arranged dispersedly in a plane direction in an array is provided such that the point light source 120 to be focused on the pupil shifts to its adjacent point light source 120 even when the observer moves.

Abstract: A display unit for displaying first and second images includes a display device, a parallax barrier arranged facing the display device, and a lenticular lens arranged facing the parallax barrier. The parallax barrier includes a plurality of slit regions. A slit control section alternately switches each slit region between a transmitting state and a shielding state at a predetermined cycle. An image signal output section provides, in synchronization with the switching of the slit region, image data to the display device so that the plurality of pixels of the display device display an image different from the image displayed before switching of the slit region.

Abstract: A display unit includes an organic electroluminescence device having light-emitting regions, and a liquid crystal panel having pixels. The liquid crystal panel is spaced apart from the organic electroluminescence device so that the light of each light-emitting region illuminates at least two pixels. An image signal output section provides data of a first image to first pixels of the liquid crystal panel and provides data of a second image to second pixels of the liquid crystal panel. The image signal output section switches the display of the first image and the display of the second image in synchronization with a switching of the emitting of the light-emitting region and non-emitting of another light-emitting region of the organic electroluminescence device by the light-emission control section.
