An apparatus for deflecting light of the present invention comprises: (a) at least one pair of transference electrodes arranged facing one another; (b) a drive circuit which applies a voltage among the transference electrodes; and (c) a liquid crystal which is inserted among the transference electrodes, and whose parallel stripes that function as a diffraction grating when the voltage is applied among the transference electrodes are produced at a pitch corresponding to the applied voltage. The light can be scanned if a diffracted light by the apparatus for deflecting light is converted into a scanning light and a voltage value is changed temporally to apply the voltage among the transference electrodes. In a device for reading information, the scanning light is reflected in a bar code and the reflected light is detected by an apparatus for detecting light. In a device for stereoscopic display of the present invention, the apparatus for deflecting light is used as beam deflection means for deflecting the light beamed from a picture element which organizes the pictures of the picture display means.

Images of an object are taken from a plurality of angles so as to generate two-dimensional images obtained from the plurality of angles. The two-dimensional images are sequentially displayed in the form of stripes by a displaying device. The two-dimensional images displayed by the displaying device are deflected by a parallel scanning part by a deflection angle dependent on the individual two-dimensional images and supplied to respective virtual apertures.

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.

A plasma arc tube display is fabricated by arranging a plurality of arc tubes having fluorescent substance layers on the inside and filled with a discharge gas, joining a front substrate and a rear substrate having electrodes to both surfaces of these arranged arc tubes, and interconnecting a plurality of plasma arc tube modules having frames facing the rear substrate with the flexible front substrate interposed therebetween to connect the electrodes installed on the front substrate to each other. Since the plasma arc tube modules can be folded, the plasma arc tube display can be easily transported even if it has a large-sized screen.

In accordance with an aspect of the present invention, a color display device (10) includes a plurality of gas discharge tubes disposed side by side. The gas discharge tubes have respective phosphor layers (4R, 4G, 4B) of different materials for different colors disposed therein and containing discharge gas therein. Each of the gas discharge tubes has a plurality of light-emitting points disposed along the length thereof. The color display device further includes a plurality of display electrodes disposed on the display screen side of the gas discharge tubes, and a plurality of signal electrodes (3) disposed on the rear side of the gas discharge tubes. Voltage control layers (6R, 6G, 6B) are disposed between the phosphor layers and the signal electrodes. The voltage control layers are made of materials which change firing voltages applied between the display electrodes and the signal electrodes. The materials of the voltage control layers are selected for the different materials of the different phosphor layers so as to minimize the difference of the firing voltages for the plurality of gas discharge tubes.

A light emitting portion and an electrode board including electrodes for driving the light emitting portion for light emission are provided as separate members. This allows the light emitting portion to have a smaller thickness, and widens the choices of substrate materials for the electrode board. Therefore, a flexible material can be used for the electrode board, thereby imparting the display device with flexibility. Further, the light emitting portion and the electrode board can be separately produced, so that the degree of freedom is increased in the production of the display device. Therefore, the light emitting portion and the electrode board can be produced in different steps or in different production lines. Further, the light emitting portion, the electrode board and other components can be individually evaluated for quality, thereby reducing the production costs of the display device.
