FIG. 1 is a cross-sectional view showing an example of the structure of a conventional terminal section, in which an electrode 2 formed on an electrode glass substrate 1 is drawn out of a sealing section 3, and a lead 4 covered with heat-resistant vinyl is pulled out. The leads are connected with solder 5, and electrical signals from an external circuit are applied to the leads. Further, in this structure, the connection portion is covered with silicone rubber 6 for the purpose of moisture resistance, and the silicone rubber and heat-resistant vinyl covering portion of the lead is covered with epoxy resin 7 to reinforce the lead from peeling. However, this structure has the disadvantage that since a large amount of epoxy resin 7 is used, the epoxy resin 7 and the electrode glass substrate 1 may peel off and crack due to the difference in expansion at low temperatures (-40 to -50 DEG C.). Furthermore, this structure also has the disadvantage that it takes a long time for the silicone rubber 6 and the epoxy resin 7 to harden. Furthermore, there is a drawback that the adhesion between the epoxy resin and the heat-resistant vinyl is poor.

信頼性の高い表示板が得られる。 In other words, the display board according to the present invention uses an ultraviolet curable adhesive, which requires almost no time for curing, so the display board production time can be significantly shortened, and it is also covered with a protective layer of silicone rubber. This prevents the terminal connections from peeling off or cracking at low temperatures, thereby improving reliability at low temperatures. In addition, the adhesion between the heat-resistant vinyl and silicone rubber that protects the external leads is excellent, and even when using a flat cable that is easy to connect to an external circuit, the surface of the cable made of heat-resistant vinyl can be easily bonded. Peeling of the protective material does not occur, and a highly reliable display board can be obtained in this respect as well.

その上、耐熱ビニールとの接着性も優れている。 Figure 2 is a cross-sectional view showing an example of the display board terminal structure according to the present invention, and 8 is the first protective layer of adhesive that is cured by ultraviolet rays and has a hardness of 60 to 85 on the Shore D scale, and the time required for curing. The process was significantly shortened from a few seconds to about 10 minutes. Furthermore, as shown by the Shore hardness value after curing, it is not only hard, but also has high adhesion strength to the glass substrate and excellent moisture resistance, which prevents the migration phenomenon between terminals that tends to occur in a structure like the one shown in Figure 1. It was also found that there was a significant decrease in However, it lacks flexibility at low temperatures (-40 to 50°C), so it should be applied only to the connection between the lead and electrode. Reference numeral 9 denotes a second protective layer of silicone rubber that hardens at room temperature, and is applied to cover the first protective layer 8 and the heat-resistant vinyl coating of the lead. This silicone rubber is flexible and has excellent flexibility at low temperatures, with no peeling or cracking occurring at the adhesive interface with the glass substrate even at -50°C.
Furthermore, it has excellent adhesion to heat-resistant vinyl.
