BACKGROUND ART Conventionally, CRT (cathode ray tube) is used as a display device.
and LCDs are often used. However, CRTs require a vacuum system, are difficult to flatten and require a large depth, and have drawbacks such as difficulty in increasing the screen size and the need to use high voltage. On the other hand, liquid crystals have a slow response speed to display drive signals, are visually dependent, and
It has the disadvantage that it is difficult to enlarge the screen because it is driven by an electric field.

FIG. 1 is a schematic perspective view showing an embodiment of the present invention. In the figure, the face plate 1 is composed of a plurality of columnar members 21 to 2n (n is a multiple of 3) having a cross section arranged in order on a plane.
On the display surface side of each of the 2n, there are fluorescent materials of the 3FIi that respond to three types of invisible light with different wavelengths and emit red, green, and blue light. (
A light-emitting layer is formed by repeatedly applying the coating in the order of B). As this type of fluorescent material 17, for example, Lumilite Color (trade name) manufactured by Shinroihi Co., Ltd. may be used. This Lumilite color is based on yttrium oxide for red emission, zinc oxide germanium dioxide for green emission, and boron calcium oxide for blue emission. The three types of invisible light include mutually different excitation wavelengths λ1. λ2 and λ3 (for example, λs -360nm, λ2 33
0 nm, λ3=300 nm) is used. Each of the columnar members 21 to 2n is sequentially irradiated with ultraviolet light of a corresponding wavelength as a light spot from the ultraviolet light generation source 4 by the optical fiber bundles 3 arranged corresponding to the pixels. In order to two-dimensionally scan the ultraviolet light spot, the ultraviolet light generation source 4 uses, for example, two polygonal mirrors arranged perpendicularly to each other and has excitation wavelengths of λ1. The configuration is such that the excitation lights of λ2 and λ3 are sequentially scanned in correspondence with R, G, and B signals, respectively.

The ultraviolet rays irradiated on the face plate 1 are transmitted to the columnar member 21.
In order to prevent ~2n from directly transmitting to the display surface side,
As shown in FIG. 2, mirrors 51 to 5n are provided on the output side of each optical fiber in the fiber bundle 3
~5n changes the traveling direction of the ultraviolet rays at right angles to guide the ultraviolet rays into the columnar members 21~2n from the side. In other words, the light receiving section and the light emitting section of the face plate 1 are unevenly distributed in a direction parallel to the display surface. Ultraviolet blocking layers 61 to 6n→ which are opaque to ultraviolet rays are provided between each of the columnar members 21 to 2n, and an ultraviolet blocking layer 7 is also provided on the display surface side of the face plate 1. In a display device having such a configuration, a light emitting layer that emits light in response to ultraviolet rays of different wavelengths is provided in a stripe shape on the display surface of the face plate 1.
Since it is configured to sequentially scan with a light spot, there is no visual dependence, and a display speed sufficient for displaying moving images can be obtained. Furthermore, since the face plate 1 itself can be made thin and lightweight, it is easy to make the entire device flat and have a large screen. Furthermore, since the ultraviolet rays are guided to the face plate 1 by the optical fiber bundle 3, the ultraviolet ray source 4 does not necessarily need to be placed behind the face plate 1, so that the entire device can be made thinner. become.

In addition, in the above embodiment, a plurality of columnar members 2 each having a cross-sectional shape are
Although the face plate 1 was constructed by arranging the elements 1 to 2n in order in a plane, as shown in FIG. The light receiving part and the light emitting part of the face plate 1 may be arranged alternately in the direction parallel to the display surface so that the ultraviolet rays do not directly pass through to the display surface. That's fine.
