置である。 The display device of a liquid crystal watch consists of a liquid crystal cell sandwiched between upper and lower polarizing plates, and some are equipped with a self-luminous illumination device to make the characters visible at night. As a type of such a lighting device, the present applicant has previously proposed a lighting device in which a self-luminous paint made of a radioactive substance is sealed under a liquid crystal display device. This device seals the self-luminous paint with a back sealing member made of white vinyl, a side sealing member made of luminescent paint or synthetic resin, and a front sealing member made of transparent polyester resin or trifluoroethylene. Since they are each made of different types of sealing materials, it is structurally difficult to handle when sealing the self-luminous paint, and the workability is extremely poor. Furthermore, since the back sealing member made of white vinyl chloride is provided only on the bottom surface to improve the reflection efficiency of the self-luminous paint, light from the self-luminous paint leaks from the side sealing member, reducing the lighting effect. , the reflection efficiency also deteriorates. The purpose of this invention is to improve the workability when sealing the self-luminous paint, eliminate light leakage from the self-luminous paint, and improve the lighting effect and reflection efficiency, thereby providing a lighting device for an LCD watch using the self-luminous paint. It is to be. The structure of the present invention is a lighting device characterized in that a back sealing member made of white vinyl chloride is formed into a box shape, and the bottom and side surfaces of the self-luminous paint are integrally covered.

ゴムである。 The present invention will be explained below with reference to the drawings. Figures 1 and 2 show the lighting device of the present invention. 1 is the lighting device, and 6 is a back sealing member that covers the back and sides, which is made of white vinyl chloride and has moisture resistance, lighting effects, and It has the effect of increasing reflection efficiency. 5 is a side sealing member that covers the side portion, and is made of luminescent paint or synthetic resin. This is because the synergistic effect of the self-luminous paint and the phosphorescent paint illuminates the display area more brightly. Reference numeral 3 denotes a front sealing member that covers the upper part, and is made of transparent polyester resin or trifluoroethylene resin, and the upper surface of the sealing member 3 is coated with white phosphorescent paint 2 having good reflection efficiency. 4 is a back sealing member 6 and a side sealing member 5
A self-luminous paint is placed in the space formed by the front sealing member 3 and is made of a composition of 147Pm, ZnS, and Cu. Note that the sealing members are sealed by thermo-pressure welding. FIG. 3 shows an example in which the above-mentioned illumination device is applied to a liquid crystal display watch, where 7 is a watch case, and 8 is a module including elements such as an oscillation section, a circuit section, and a battery section. The illumination device 1 is engaged in a recess 9 of the module 8 and is fixed to the module 8 by a holding frame 10 in a liquid crystal cell portion of a liquid crystal display section 12. In addition, 11 is module 8
It is a conductive rubber that transmits electrical signals from the liquid crystal display device 12 to the liquid crystal display device 12.

刻表示をすることができる。 The lighting device 1 is in direct contact with the lower side of the liquid crystal display device 12 and illuminates the entire surface of the liquid crystal display section 12 at all times, but during the daytime, the white phosphorescent paint 2 provided on the top surface of the lighting device 1 reflects external light. In addition, the luminescent paint 2 is excited by external light, thereby making it possible to display the time brightly and clearly. Furthermore, since the self-luminous paint 4 and the side sealing member 5 have different colors, if you look at them from above, you will be able to tell the difference between the two, which is not desirable, but in this device, white luminescent paint is used. 2 is thinly covered, making the distinction between the two inconspicuous. At night, light emitted from the self-luminous paint 4 passes through each part and illuminates the time display device 12. At this time, as shown in FIG. 3, a back sealing member 6 made of white vinyl chloride is used to prevent light from the self-luminous paint 4 and the phosphorescent paint 5 of the side sealing member from leaking from the side surface and to increase reflection efficiency. As a result, the time display device 1 can be efficiently illuminated with light, and the time can be displayed brightly and clearly.

Furthermore, when sealing the self-luminous paint, it is simply placed in a box-shaped container made of white vinyl chloride, making it extremely easy to handle and workable compared to conventional sealing structures.
Efficiency can be increased several steps.
