The driver can visually recognize a warning display pattern made using ink that can be visually recognized by the ultraviolet light. As a result, the warning display pattern differs between daytime and nighttime, and the visibility is improved.

(Examples) Hereinafter, the present invention will be described in detail with reference to the drawings by using examples.

FIG. 1 shows an embodiment of the display device of the present invention, and shows an instrument panel 5 located in front of a driver's seat of a vehicle. On the display panel of the instrument panel 5, in addition to the speedometer 6 for displaying the speed of the vehicle, a fuel gauge 7 for indicating the remaining fuel and a water temperature gauge 8 for indicating the temperature of the cooling water are installed as main instruments. I have. The instrument panel 5 has, in addition to these instruments, a direction indicator 9 for monitoring the operation state of the vehicle, charging of the battery, overheating of the exhaust gas purification device, amount of oil, operating state of the handbrake, and door operation. A warning indicator 10 indicating the locked state of the vehicle is provided, and is turned on and off according to the driving state of the vehicle.

FIG. 2 shows a cross section taken along line AA of the instrument panel 5 of FIG. In the figure, reference numeral 50 denotes a case of the instrument panel 5, reference numeral 51 denotes a facing provided on the front side thereof, and a cover 20 made of a transparent member such as glass or plastic is attached to the front side thereof. A display plate (character plate) 30 is attached, and further thereon, an ultraviolet lamp 40 as a black light for irradiating the display plate 30 with ultraviolet light 41 as excitation light is attached. A movement 70 for driving a pointer 60 of the speedometer 6 disposed in the front of the display panel 30 is provided in the case 50 on the rear side of the above-mentioned facing 51.

In the instrument panel 5 configured as described above, in the present invention, the direction indicator 9 and a warning for indicating the charging of the battery, the overheating of the exhaust gas purification device, the amount of oil, the operating state of the handbrake, the locked state of the door, and the like. The design of the display device 10 is printed on the display plate 30 using both the ultraviolet light emitting ink and the visible light ink. This printing method is described, for example, in the direction indicator 9.
Will be described as an example.

FIG. 3 shows an example of a method of printing the design pattern of the direction indicator 9. First, the design pattern of the direction indicator is printed on the surface of the display panel 30 using the ink U that emits ultraviolet light, and then the design pattern of the direction indicator is printed using the visible light ink V. Print over the top. At this time, the design pattern of the direction indicator using the ink U that emits light by ultraviolet light is printed smaller than the design pattern of the direction indicator using the visible light ink V (indicated by a two-dot chain line in FIG. 3), and In the design pattern of the direction indicator using the visible light ink V, a portion overlapping with the portion previously printed with the ink U which emits light by ultraviolet light was thinly extracted along the outer shape of the design pattern of the direction indicator. A hollow portion E is provided.

By printing the direction indicator in this way, it becomes possible to include an ultraviolet light-emitting design in the visible light design, and in the daylight visible light, as shown in FIG. And the ultraviolet light emitting design using the ink U appear to overlap, and the design pattern of a normal direction indicator looks large. On the other hand, when the ultraviolet lamp emits light at night, as shown in FIG. 6, the visible light design printed using the visible light ink V with ultraviolet light is not visible, and the ink U is included in the visible light design.
Only the ultraviolet light-emitting design printed using is seen sharply in a thin line through the hollow portion E.

FIG. 4 shows another example of the method of printing the design pattern of the direction indicator 9. In FIG. In this example, the design pattern of the direction indicator is first printed on the surface of the display panel 30 using the visible light ink V larger than the design pattern of the direction indicator using the ink U that emits ultraviolet light. A design pattern of the direction indicator using the ink U which emits light by ultraviolet rays is printed on the design pattern of the direction indicator using the visible light ink V printed earlier. At this time, the design pattern of the direction indicator using the ink U that emits ultraviolet light is smaller than the design pattern of the direction indicator using the visible light ink V (indicated by a two-dot chain line in FIG. 4), and Printing is performed by providing a hollow portion E in which a central portion of the ink U is removed along the outer shape.

Even when printing is performed as described above, when visible light is used in the daytime, as shown in FIG.
When the ultraviolet light design using the LED overlaps, the design pattern of the ordinary direction indicator can be seen, and when the ultraviolet lamp is lit at night, the visible light design printed using the visible light ink V is invisible as shown in FIG. Only the ultraviolet light-emitting designs printed linearly through the hollow portions E using the ink U in the visible light designs are visible.

Therefore, in the display device of the present invention, the visibility of the design pattern by ultraviolet light and the visibility of the design pattern by visible light can be changed.
