Fig. 4 (a) is the local amplification plan view that is arranged in each wiring layer 15a～15e of X1 side no-input zone territory 12a shown in Figure 1.Shown in Fig. 4 (a), each wiring layer 15a～15e constitutes possesses connection end 23a～23e, the distribution extension 24a～24e from each connection end 23a～23e along the extension of Y1-Y2 direction that is arranged on the link position that is connected with the end of each lower electrode layer 14.
At this; For each boundary that connects end 23a～23e and each distribution extension 24a～24e; In the embodiment of Fig. 4, said boundary is confirmed by stage portion 23a1～23e1, in each wiring layer 15a～15e; Leaning on the part of Y1 side to be defined as than said stage portion 23a1～23e1 connects end 23a～23e, leans on the part of Y2 side to be defined as distribution extension 24a～24e than said stage portion 23a1～23e1.Each connects end 23a～23e and in each wiring layer 15a～15e, has the maximum zone of distribution width.Need to prove where the boundary that connects end 23a～23e and distribution extension 24a～24e can be according to the suitably settings such as form of wiring layer if being set in.Each X2 side end 23a2～23e2 that connects end 23a～23e forms rectilinear form on the Y1-Y2 direction, and is arranged in row.The connection end 23e of wiring layer 15e compares and forms maximumly with other the end 23a～23d that is connected, and forms the essentially rectangular shape.On the other hand, connect end 23a～23d and have dip plane 23a3～23d3 at the X1 side end, it is and connects the different shape of end 23e.Each size that connects end 23a～23e forms by following order,, connects end 23a＜connection end 23b＜connection end 23c＜connection end 23d＜connection end 23e that is.
Next, distribution extension 24a～24e is described.Distribution extension 24a～24e is meant connection end 23a～23e and the part beyond the external connecting shown in Figure 1 27 among wiring layer 15a～15e.Each distribution extension 24a～24e unrolls to X1 side no-input zone territory 12a and Y2 side no-input zone territory 12b.The length dimension that is formed on the distribution extension 24a～24e on the X1 side no-input zone territory 12a forms according to following order, that is, and and distribution extension 24a＜distribution extension 24b＜distribution extension 24c＜distribution extension 24d＜distribution extension 24e.
In this embodiment, the distribution width of each distribution extension 24a～24e (width dimensions on the X1-X2 direction) is characterised in that the few more zone of number with the said wiring layer that on the X1-X2 direction, is set up in parallel forms greatly more.
The distribution width of each the distribution extension 24a～24e that respectively illustrates the zone corresponding of Fig. 4 (b) with Fig. 4 (a).In the zone of Fig. 4 (b-5), shown in Fig. 4 (a), all distribution extension 24a～24e are set up in parallel in the X1-X2 direction sky with opening predetermined distance.Thus, in the zone of each the distribution extension 24a～24e shown in Fig. 4 (b-5), the distribution width forms minimumly in each distribution extension 24a～24e.
Next; Be arranged in than the zone shown in Fig. 4 (b-5) by the zone shown in Fig. 4 (b-4) of the position of Y1 side; Shown in Fig. 4 (a); Do not form distribution extension 24a, the distribution extension 24b～24e that lacks than the zone shown in Fig. 4 (b-5) is set up in parallel in the X1-X2 direction sky with opening predetermined distance.Thus, the distribution width of each the distribution extension 24b～24e in the zone of Fig. 4 (b-4) forms greatlyyer than the distribution width of each the distribution extension 24b～24e among Fig. 4 (b-5).
Next; Be arranged in than the zone shown in Fig. 4 (b-4) by the zone shown in Fig. 4 (b-3) of the position of Y1 side; Shown in Fig. 4 (a); Do not form distribution extension 24a, 24b, the distribution extension 24c～24e that lacks than the zone shown in Fig. 4 (b-4) is set up in parallel in the X1-X2 direction sky with opening predetermined distance.Thus, the distribution width of each the distribution extension 24c～24e in the zone of Fig. 4 (b-3) forms greatlyyer than the distribution width of each the distribution extension 24c～24e among Fig. 4 (b-4).
Next; Be arranged in than the zone shown in Fig. 4 (b-3) by the zone shown in Fig. 4 (b-2) of Y1 side; Shown in Fig. 4 (a), do not form distribution extension 24a～24c, the distribution extension 24d, the 24e that lack one than Fig. 4 (b-3) are set up in parallel in the X1-X2 direction sky with opening predetermined distance.Thus, the distribution width of each the distribution extension 24d in the zone of Fig. 4 (b-2), 24e forms greatlyyer than the distribution width of each the distribution extension 24d among Fig. 4 (b-3), 24e.
Next, lean on the zone shown in Fig. 4 (b-1) of Y1 side being arranged in than the zone shown in Fig. 4 (b-2), shown in Fig. 4 (a), do not form distribution extension 24a～24d, only distribution extension 24e is provided with along the X1-X2 direction.Thus, the distribution width of the distribution extension 24e in the zone of Fig. 4 (b-1) forms greatlyyer than the distribution width of each the distribution extension 24e among Fig. 4 (b-2).
Thus; Shown in Fig. 4 (b-1)～Fig. 4 (b-5); Form the distribution width in each zone according to following order; That is, during distribution width in each zone of observing distribution extension 24e, the width dimensions T1 among the width dimensions T2＜Fig. 4 (b-1) among the width dimensions T3＜Fig. 4 (b-2) among the width dimensions T4＜Fig. 4 (b-3) among the width dimensions T5＜Fig. 4 (b-4) among Fig. 4 (b-5).
In Fig. 4 (b-1)～Fig. 4 (b-5); In each zone; The distribution width of each the distribution extension 24a～24e that is set up in parallel along the X1-X2 direction forms with identical width dimensions T2～T5; But for example shown in Fig. 4 (c-1)～Fig. 4 (c-3), the distribution width that also can constitute in each zone each the distribution extension 24a～24e that is set up in parallel along the X1-X2 direction forms with the different widths size.In each zone of Fig. 4 (c-1)～Fig. 4 (c-3), the distribution width is adjusted to respectively according to following order and becomes big, that is, and and distribution extension 24e＞distribution extension 24d that distribution length is long ...
So; In this embodiment; The distribution width of each distribution extension 24a～24e is not to form with thin fixed width as in the past, the zone that the number of the wiring layer that is set up in parallel is few, and the distribution width of each distribution extension 24a～24e forms greatly more.Thus,, in the few zone of the number of the wiring layer that is set up in parallel, also can correspondingly form the distribution width greatly even the length dimension of distribution extension is long, therefore can with compared the probability that reduces broken string effectively in the past.When observing the longest distribution extension 24e of distribution length; Each zone from Fig. 4 (b-5) to Fig. 4 (b-1) can make the distribution width become big gradually; Therefore regardless of the number of the wiring layer that is set up in parallel; With make the distribution width form the little situation in the past of width without exception to compare, can reduce the probability of the broken string of distribution extension 24e effectively.
And then in this embodiment, the distribution width of each distribution extension can form following mode, that is, the length dimension of distribution extension is long more, and the distribution width of each distribution extension on average forms greatly more.Promptly; Can form according to following order; That is the distribution width (on average) of the distribution width (on average) of the distribution width (on average) of the distribution width (on average) of the distribution width (on average) of distribution extension 24a＜distribution extension 24b＜distribution extension 24c＜distribution extension 24d＜distribution extension 24e.Thus, can make the deviation ratio of wiring resistance of each wiring layer 15a～15e in the past little.
In addition, in this embodiment, if be example with distribution extension 24d, the distribution width that then is formed with the X1-X2 direction at distribution extension 24d is towards change width zone 24d1～24d3 that the Y1-Y2 direction gradually changes.In addition; The last fixed width zone of extending abreast with the Y1-Y2 direction that is connected with continuously of 24d1～24d3 forms the shape that is linked in sequence according to fixed width zone-24d1-fixed width zone, change width zone-24d2-fixed width zone, change width zone-24d3-fixed width zone, change width zone in the change width zone.Shown in Fig. 4 (a), each change width zone 24d1～24d3 forms from the bending of width FX.So, through change width zone 24d1～24d3 is formed with the mode of bending, thereby can in limited X1 side no-input zone territory 12a, dispose a plurality of distribution extension 24a～24e efficiently.Need to prove,, be that example is illustrated with distribution extension 24d, but also the change width zone can be set equally for other distribution extensions 24b～24e for the change width zone.But the distribution length of distribution extension 24a is the shortest, and is among the X1 side no-input zone territory 12a all the time and full distribution extension opposed position relation, therefore need not to form the change width zone and then forms the distribution width of distribution extension 24a little.That is, can form with fixing distribution width for distribution extension 24a.Be formed with the change width zone that the distribution width gradually changes being arranged in outermost distribution extension 24e, but do not form from the bending of width FX, the X1 side end 24e1 of distribution extension 24e forms the shape of linearly extending along the Y1-Y2 direction.
In addition, shown in Fig. 4 (a), the tilt angle theta 1 with respect to the Y1-Y2 direction of the side end 25 of each change width zone 24d1～24d3 is preferably more than 0 ° and below 45 °.Regional through forming change width with such tilt angle theta 1, thus especially in manufacturing approach, can expect following effect.
Fig. 8 is a process chart of the manufacturing approach of the lower basal plate 22 in this embodiment of expression.In the operation shown in Fig. 8 (a), on whole on the lower substrate 32, form the transparency conducting layer 16 of ITO etc. through sputtering method or vapour deposition method etc.And then, on surperficial whole of transparency conducting layer 16, form metal material layer 35 through sputtering method or vapour deposition method etc.
Next, in the operation of Fig. 8 (b), on the surface in the no-input zone territory 12 of metal material layer 35, be formed with the resist layer 36 that the pattern by each wiring layer 15a～15j constitutes through photoetching technique.That is, form the resist layer 36 of the plane pattern that possesses wiring layer 15a～15e shown in Figure 4.Thus, on resist layer 36, have the tilt angle theta 1 shown in Fig. 4 (a) and form the change width zone.The tilt angle theta 1 of this moment is preferably greater than 0 ° and below 45 °.
And, for example remove the metal material layer 35 that is not covered by said resist layer 36 through wet etching.At this moment; Through having greater than 0 ° and forming the sidepiece in change width zone in the tilt angle theta below 45 ° 1; Thereby the corner part (the for example part of the symbol A of Fig. 4 (a)) in zone does not become the right angle from the width FX to change width; Tilting gently changes, and therefore can suppress the situation that etching solution accumulates at said corner part generation liquid.Therefore, can suitably form distribution extension 24a～24e of each wiring layer 15a～15e with the distribution width of regulation.
In the operation of Fig. 8 (c), upward form resist layer 37 to transparency conducting layer 16 from each wiring layer 15 (same Fig. 8 (c)) by symbol 15 expressions.In input area 11, said resist layer 37 is formed the electrode pattern identical with each lower electrode layer 14 through photoetching technique, and in no-input zone territory 12, form continuously with the Wiring pattern that covers on each wiring layer 15 with said electrode pattern.Then, remove the transparency conducting layer 16 that is not covered by said resist layer 37.Thus, each lower electrode layer 14 shown in Figure 1 can be on input area 11, formed, in no-input zone territory 12, transparency conducting layer 16 can be below each wiring layer 15, retained.Can also use above-mentioned manufacturing approach to form upper substrate 21.Need to prove that above-mentioned manufacturing approach is an example at most just, also can form each substrate 21,22 through other manufacturing approach.
Need to prove, also can form each wiring layer through print processes such as serigraphy, intaglio printing, ink jet printings.In addition, can use Ag paste, Ag nano material, Cu nano material etc. as wiring layer.
Need to prove that distribution structure shown in Figure 4 not only goes for lower basal plate 22, and go for upper substrate 21.As shown in Figure 2, for the wiring layer 18a～18g of upper substrate 21, the number of the wiring layer that on the Y1-Y2 direction, is set up in parallel changes towards the X1-X2 direction.Thus; Can the distribution width (width dimensions of Y1-Y2 direction) of the distribution extension that extends along the X1-X2 direction of each wiring layer 18a～18g be formed following mode; That is this distribution width of zone that the number of the wiring layer that, on the Y1-Y2 direction, is set up in parallel is few more is big more.
In Fig. 3; In the top electrode layer 13 of the lower electrode layer 14 of lower basal plate 22 and upper substrate 21 all under the state of operating surface 20a side; 21 of lower basal plate 22 and upper substrate engage via tack coat 30, but also can be as Fig. 5, form make lower basal plate 22 lower electrode layer 14 towards operating surface 20a side; Make the state of the top electrode layer 13 of upper substrate 21 towards the opposition side of operating surface 20a side; And can engage via tack coat 30 between lower basal plate 22 and the upper substrate 21, perhaps also can be as shown in Figure 6, the upper and lower surfaces that is employed in a base material 38 forms the mode of lower electrode layer 14 and top electrode layer 13.
