摘要:
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.

摘要:
A display device capable of realizing a desired color temperature is provided. Phosphor layers (5a,5b,5c) which are excited by ultraviolet radiation produced by discharge and emit red, green and blue visible light, are formed inside a red, green and blue gas discharge tube (1a,1b,1c) respectively. The height (Yc) of the phosphor layer (5c) with respect to a rear support body (20) is higher than the heights (Ya,Yb) of the phosphor layers (5a,5b) with respect to the rear support member (20), and establishes the relationship Yc > Ya = Yb. Therefore, the distance from the phosphor layer (5c) to the opposite discharge surface on a front support body is shorter than those from the phosphor layers (5a,5b), the visible light emitted from the display device (10) is shifted toward blue, that is, the color temperature increases.
