The display device further including: a plurality of display electrodes (2) formed on a surface of the front support plate facing the gas discharge tubes to extend across the axial direction of the gas discharge tubes; and a plurality of signal electrodes (3) formed on a surface of the rear support plate facing the gas discharge tubes to extend along the longitudinal direction of the gas discharge tubes. The plurality of signal electrodes are divided into a plurality of groups (B1, B2, . . . , Ba). Each group includes a predetermined number of signal electrodes. The distance between adjacent ones of the signal electrodes in each group has a first distance. The distance between adjacent ones of said signal electrodes in each group is substantially equal to a first distance (PT). The distance between the signal electrode at an end of each group of the signal electrodes and the signal electrode at the adjacent end of the adjacent group is substantially equal to a second distance (PG) that is larger than the first distance.

In order to realize a display having good contrast and stable addressing by using a gas discharge display device having a screen of a three-electrode surface discharge structure having a characteristics that a counter discharge start voltage is higher than a surface discharge start voltage, prior to starting of initialization of an electrified state as canceling of setting of addressing that was performed last, positive charge is formed between opposed electrodes so that a discharge can be generated easily in the addressing after the initialization, and the initialization is performed so that the formed positive charge does not vanish.

A hologram of a virtual object or an object which actually exists is formed and a solid image is displayed. 3-dimensional information of the object to be displayed is divided into regions in the depth direction. Depth images are formed as 2-dimensional images where are seen from a plurality of points which are obtained by finely dividing the hologram forming surface for every region. A phase distribution at the hologram forming surface is calculated from the depth images and displayed on a liquid crystal display or the like as an electronic hologram. A reference light is irradiated onto the display and is converted into an optical wave front, thereby displaying a solid image. When forming a hologram recording medium, a zone image corresponding to each of the finely divided exposure regions of a dry plate is exposed multiple times.

An optical deflector device includes a VGM cell including a film of a nematic liquid crystal material which generates a distribution of spatial frequencies when subjected to an electric field. A film thickness setting unit sets a thickness distribution of the film in the VGM cell in accordance with a film thickness distribution defined by a predetermined function.

An image display to display a 2-dimensional image and a beam deflector to deflect the lights from the pixels constructing the image of the image display are provided. The beam deflector is arranged closely in front of the image display. A plurality of 2-dimensional images of different visual directions are sequentially displayed in the image display. The light from each pixel is deflected by the beam deflector synchronously with the display of the 2-dimensional image so that the light from each pixel is directed to the region in which the visual point has been set in order to obtain each image. The switching operation in this instance is executed at a high speed.

A plurality of 2-dimensional images of different visual directions, when an object to be displayed is seen from different directions, are inputted to an input section by photographing an object using cameras. The 2-dimensional images are then subjected to enlargement, reduction, and movement of the coordinate position, thereby adjusting the size and position of the solid image. A phase distribution at a hologram forming surface is then calculated by a phase calculating section. The phase distribution is calculated from a plurality of 2-dimensional images of red, green, and blue components, and the reproduction light of each color is irradiated, thereby displaying a color solid image. The calculated phase distribution is expressed on a hologram forming surface of a phase expressing section using a display. A reproduction light is then irradiated and converted into an optical wave front, to thereby display a solid image. The 2-dimensional images obtained by photographing can be also formed by interpolating calculations from the two 2-dimensional images which were acctually photographed.

The position of a solid image which changes with the elapse of time is detected. The position of a virtual screen is set so that a distance from an object enters an allowable range such as to reduce a fatigue of an observer. A 2-dimensional image is formed at the set virtual screen position. A phase distribution is calculated at the hologram forming surface, thereby displaying a solid image. Even when the position of a solid image changes with the elapse of time, the fatigue of the eyes can be minimized.
