As shown in Fig. 8 (not illustrating half tone), although the first signal line material 131 ', secondary signal wire material 132 ' and the 3rd signal line material 133 ' are formed at substrate respectively by the signal wire perforate be separated, but, due to the mobility of signal line material, adjacent binary signal wire material is made to be formed at flowing after on substrate 110 and to link together.Illustrate with secondary signal wire material 132 ' for the first signal line material 131 ', when the first signal line material 131 ' and secondary signal wire material 132 ' are formed at after on substrate 110 respectively by the first signal wire perforate 221 and secondary signal line perforate 222, the first signal line material 131 ' and secondary signal wire material 132 ' can flow over interval S 2 and in electrical contact each other.Say further, first signal wire perforate 221 and secondary signal line perforate 222 are formed at after on substrate 110, first signal line material 131 ' can flow to secondary signal wire material 132 ' and be contacted with secondary signal wire material 132 ', and secondary signal wire material 132 ' can flow to the first signal line material 131 ' and be contacted with the first signal line material 131 '

Under the design of above-mentioned interval S 2 (Fig. 5 B), first signal line material 131 ' is after flowing, its first protuberance 131a can flow to the secondary signal wire material 132 ' of contiguous secondary signal wire material 132 ' and contact vicinity, makes the first signal line material 131 ' in electrical contact with secondary signal wire material 132 ' by the flowing of the first protuberance 131a.In addition, under the design of interval S 2, secondary signal wire material 132 ' is after flowing, its second protuberance 132a can flow to the first contiguous signal line material 131 ' and the first signal line material 131 ' of contact vicinity, makes secondary signal wire material 132 ' in electrical contact with secondary signal wire material 132 ' by the flowing of the second protuberance 132a.

When the first protuberance 131a and the second protuberance 132a is formed simultaneously, the first protuberance 131a and the second protuberance 132a flows to the other side respectively and contacts with each other in shorter flow distance.Thus, the first signal line material 131 ' and secondary signal wire material 132 ' can contact rapidly before cooled and solidified.In one embodiment, interval S 2 can between about between 5 to 10um.

As shown in Figure 9, in the flowing of the first signal line material 131 ', secondary signal wire material 132 ' and the 3rd signal line material 133 ', after contact, the first signal line material 131 ', secondary signal wire material 132 ' and the 3rd signal line material 133 ' form signal transmssion line 130.
