Fig. 4 (a) is the close-up top view of each wiring layer 15a ~ 15e being arranged in non-input region, the X1 side 12a shown in Fig. 1.As shown in Fig. 4 (a), each wiring layer 15a ~ 15e is configured to possess the connecting end portion 23a ~ 23e being arranged on the link position be connected with the end of each lower electrode layer 14, the distribution extension 24a ~ 24e extended along Y1-Y2 direction from each connecting end portion 23a ~ 23e.
At this, for the boundary of each connecting end portion 23a ~ 23e and each distribution extension 24a ~ 24e, in the embodiment illustrated in fig. 4, described boundary is determined by stage portion 23a1 ~ 23e1, in each wiring layer 15a ~ 15e, lean on the part of Y1 side to be defined as connecting end portion 23a ~ 23e than described stage portion 23a1 ~ 23e1, lean on the part of Y2 side to be defined as distribution extension 24a ~ 24e than described stage portion 23a1 ~ 23e1.Each connecting end portion 23a ~ 23e has the maximum region of wiring width in each wiring layer 15a ~ 15e.It should be noted that, the boundary of connecting end portion 23a ~ 23e and distribution extension 24a ~ 24e is set in and where suitably can sets according to the form etc. of wiring layer.The X2 side end 23a2 ~ 23e2 of each connecting end portion 23a ~ 23e is formed as rectilinear form on Y1-Y2 direction, and is arranged in row.The connecting end portion 23e of wiring layer 15e is formed maximum compared with other connecting end portion 23a ~ 23d, and is formed as substantially rectangular shape.On the other hand, connecting end portion 23a ~ 23d has dip plane 23a3 ~ 23d3 at X1 side end, and it is the shape different from connecting end portion 23e.The size of each connecting end portion 23a ~ 23e is formed in the following order, that is, connecting end portion 23a < connecting end portion 23b < connecting end portion 23c < connecting end portion 23d < connecting end portion 23e.
Next, distribution extension 24a ~ 24e is described.Distribution extension 24a ~ 24e refers to the part beyond the external connecting 27 shown in connecting end portion 23a ~ 23e and Fig. 1 in wiring layer 15a ~ 15e.Each distribution extension 24a ~ 24e unrolls to X1 side non-input region 12a and non-input region, Y2 side 12b.The length dimension being formed in the distribution extension 24a ~ 24e on the 12a of non-input region, X1 side is formed in the following order, that is, distribution extension 24a < distribution extension 24b < distribution extension 24c < distribution extension 24d < distribution extension 24e.
In the present embodiment, the feature of the wiring width (width dimensions on X1-X2 direction) of each distribution extension 24a ~ 24e is, the region having the number of the described wiring layer be set up in parallel on X1-X2 direction fewer is formed larger.
The wiring width respectively illustrating each distribution extension 24a ~ 24e in the region corresponding with Fig. 4 (a) of Fig. 4 (b).In the region of Fig. 4 (b-5), as shown in Fig. 4 (a), all distribution extension 24a ~ 24e are set up in parallel in overhead, X1-X2 direction with opening predetermined distance.Thus, the region of each distribution extension 24a ~ 24e shown in Fig. 4 (b-5), in each distribution extension 24a ~ 24e, wiring width is formed minimum.
Next, be arranged in than the region shown in Fig. 4 (b-5) by Y1 side position Fig. 4 (b-4) shown in region, as shown in Fig. 4 (a), do not form distribution extension 24a, be set up in parallel with opening predetermined distance in overhead, X1-X2 direction than the distribution extension 24b ~ 24e in few one of region shown in Fig. 4 (b-5).Thus, the wiring width of each distribution extension 24b ~ 24e in the region of Fig. 4 (b-4) is formed larger than the wiring width of each distribution extension 24b ~ 24e in Fig. 4 (b-5).
Next, be arranged in than the region shown in Fig. 4 (b-4) by Y1 side position Fig. 4 (b-3) shown in region, as shown in Fig. 4 (a), do not form distribution extension 24a, 24b, be set up in parallel with opening predetermined distance in overhead, X1-X2 direction than the distribution extension 24c ~ 24e in few one of region shown in Fig. 4 (b-4).Thus, the wiring width of each distribution extension 24c ~ 24e in the region of Fig. 4 (b-3) is formed larger than the wiring width of each distribution extension 24c ~ 24e in Fig. 4 (b-4).
Next, be arranged in than the region shown in Fig. 4 (b-3) by Y1 side Fig. 4 (b-2) shown in region, as shown in Fig. 4 (a), do not form distribution extension 24a ~ 24c, be set up in parallel with opening predetermined distance in overhead, X1-X2 direction than distribution extension 24d, 24e of few one of Fig. 4 (b-3).Thus, the wiring width of each distribution extension 24d, 24e in the region of Fig. 4 (b-2) is formed larger than the wiring width of each distribution extension 24d, 24e in Fig. 4 (b-3).
Next, be arranged in than the region shown in Fig. 4 (b-2) by Y1 side Fig. 4 (b-1) shown in region, as shown in Fig. 4 (a), do not form distribution extension 24a ~ 24d, only distribution extension 24e is arranged along X1-X2 direction.Thus, the wiring width of the distribution extension 24e in the region of Fig. 4 (b-1) is formed larger than the wiring width of each distribution extension 24e in Fig. 4 (b-2).
Thus, as shown in Fig. 4 (b-1) ~ Fig. 4 (b-5), form the wiring width in each region in the following order, namely, during wiring width in each region observing distribution extension 24e, the width dimensions T1 in width dimensions T2 < Fig. 4 (b-1) in width dimensions T3 < Fig. 4 (b-2) in width dimensions T4 < Fig. 4 (b-3) in width dimensions T5 < Fig. 4 (b-4) in Fig. 4 (b-5).
In Fig. 4 (b-1) ~ Fig. 4 (b-5), in each region, the wiring width of each distribution extension 24a ~ 24e be set up in parallel along X1-X2 direction is formed with identical width dimensions T2 ~ T5, but such as shown in Fig. 4 (c-1) ~ Fig. 4 (c-3), the wiring width that also can be configured to each distribution extension 24a ~ 24e be set up in parallel along X1-X2 direction in each region is formed with different width dimensions.In each region of Fig. 4 (c-1) ~ Fig. 4 (c-3), wiring width is adjusted to respectively and becomes large according to following order, that is, the distribution extension 24e > distribution extension 24d that wiring lengths is long ...
So, in the present embodiment, the wiring width of each distribution extension 24a ~ 24e is not formed with thin fixed width as in the past, the region that the number of the wiring layer be set up in parallel is few, and the wiring width of each distribution extension 24a ~ 24e is formed larger.Thus, even if the length ruler modest ability of distribution extension, in the region that the number of the wiring layer be set up in parallel is few, also can correspondingly wiring width be formed greatly, therefore, it is possible to the probability effectively reducing broken string compared with the past.When the distribution extension 24e that observation wiring lengths is the longest, from Fig. 4 (b-5) to Fig. 4, each region of (b-1) can make wiring width become large gradually, therefore regardless of the number of the wiring layer be set up in parallel, be formed as without exception with making wiring width compared with the little situation in the past of width, effectively to reduce the probability of the broken string of distribution extension 24e.
And then in the present embodiment, the wiring width of each distribution extension can be formed as under type, that is, the length dimension of distribution extension is longer, and the wiring width of each distribution extension is on average formed larger.Namely, can be formed in the following order, that is, the wiring width (on average) of wiring width (on average) the < distribution extension 24e of wiring width (on average) the < distribution extension 24d of wiring width (on average) the < distribution extension 24c of wiring width (on average) the < distribution extension 24b of distribution extension 24a.Thereby, it is possible to make the deviation ratio of the wiring resistance of each wiring layer 15a ~ 15e in the past little.
In addition, in the present embodiment, if for distribution extension 24d, then wide variety region 24d1 ~ 24d3 that the wiring width being formed with X1-X2 direction at distribution extension 24d gradually changes towards Y1-Y2 direction.In addition, wide variety region 24d1 ~ 24d3 is connected with width fixed area continuously that extend abreast with Y1-Y2 direction, is formed as the shape be linked in sequence according to width fixed area-wide variety region 24d1-width fixed area-wide variety region 24d2-width fixed area-wide variety region 24d3-width fixed area.As shown in Fig. 4 (a), each wide variety region 24d1 ~ 24d3 is formed from the bending of width fixed area.So, by being formed in the mode of bending by wide variety region 24d1 ~ 24d3, thus multiple distribution extension 24a ~ 24e can be configured efficiently in limited non-input region, X1 side 12a.It should be noted that, for wide variety region, be illustrated for distribution extension 24d, but also can wide variety region be set equally for other distribution extensions 24b ~ 24e.But the wiring lengths of distribution extension 24a is the shortest, and be in position relationship opposed with full distribution extension all the time in the 12a of non-input region, X1 side, therefore without the need to forming wide variety region and then being formed little by the wiring width of distribution extension 24a.That is, can be formed with fixing wiring width for distribution extension 24a.Be formed with the wide variety region that wiring width gradually changes being arranged in outermost distribution extension 24e, but be not formed as from the bending of width fixed area, the X1 side end 24e1 of distribution extension 24e is formed as the shape extended straight along Y1-Y2 direction.
In addition, as shown in Fig. 4 (a), the side end 25 of each wide variety region 24d1 ~ 24d3 be preferably greater than 0 ° relative to the tilt angle theta 1 in Y1-Y2 direction and below 45 °.By forming wide variety region with such tilt angle theta 1, thus following effect can be expected especially in a manufacturing method.
Fig. 8 is a process chart of the manufacture method of the lower basal plate 22 represented in present embodiment.In the operation shown in Fig. 8 (a), whole in lower substrate 32 is formed the transparency conducting layer 16 of ITO etc. by sputtering method or vapour deposition method etc.And then, whole of the surface of transparency conducting layer 16 forms metal material layer 35 by sputtering method or vapour deposition method etc.
Next, in the operation of Fig. 8 (b), the surface in the non-input region 12 of metal material layer 35 is formed with by photoetching technique the resist layer 36 be made up of the pattern of each wiring layer 15a ~ 15j.That is, the resist layer 36 possessing the plane pattern of the wiring layer 15a ~ 15e shown in Fig. 4 is formed.Thus, resist layer 36 have the tilt angle theta 1 shown in Fig. 4 (a) and form wide variety region.Tilt angle theta 1 is now preferably greater than 0 ° and below 45 °.
Further, such as removed not by metal material layer 35 that described resist layer 36 covers by wet etching.Now, 0 ° is greater than and tilt angle theta 1 below 45 ° and form the sidepiece in wide variety region by having, thus the corner part (part of the symbol A of such as Fig. 4 (a)) from width fixed area to wide variety region does not become right angle, the change of steep ground, therefore, it is possible to suppress the situation that etching solution accumulates at described corner part generation liquid.Therefore, it is possible to suitably form the distribution extension 24a ~ 24e of each wiring layer 15a ~ 15e with the wiring width of regulation.
In the operation of Fig. 8 (c), from each wiring layer 15 (same Fig. 8 (c) represented by symbol 15), form resist layer 37 to transparency conducting layer 16.In input area 11, described resist layer 37 is formed as the electrode pattern identical with each lower electrode layer 14 by photoetching technique, and is formed with the Wiring pattern covered on each wiring layer 15 in non-input region 12 continuously with described electrode pattern.Then, removing is not by transparency conducting layer 16 that described resist layer 37 covers.Thereby, it is possible to form each lower electrode layer 14 shown in Fig. 1 on input area 11, in non-input region 12, transparency conducting layer 16 can be retained in the below of each wiring layer 15.Above-mentioned manufacture method can also be used to form upper substrate 21.It should be noted that, above-mentioned manufacture method is an example at most just, also can form each substrate 21,22 by other manufacture method.
It should be noted that, also can form each wiring layer by print processes such as serigraphy, intaglio printing, ink jet printings.In addition, Ag paste, Ag nano material, Cu nano material etc. can be used as wiring layer.
It should be noted that, the distribution structure shown in Fig. 4 not only goes for lower basal plate 22, and goes 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 Y1-Y2 direction is set up in parallel changes towards X1-X2 direction.Thus, can the wiring width (width dimensions in Y1-Y2 direction) of the distribution extension extended along X1-X2 direction of each wiring layer 18a ~ 18g be formed as under type, that is, this wiring width of region that the number of wiring layer Y1-Y2 direction is set up in parallel is fewer is larger.
In figure 3, in the lower electrode layer 14 of lower basal plate 22 and the top electrode layer 13 of upper substrate 21 all towards under the state of operating surface 20a side, engage via tack coat 30 between lower basal plate 22 with upper substrate 21, but also can be as shown in Figure 5, be formed as making the lower electrode layer 14 of lower basal plate 22 towards operating surface 20a side, make the top electrode layer 13 of upper substrate 21 towards the state of the opposition side of operating surface 20a side, and can engage via tack coat 30 between lower basal plate 22 with upper substrate 21, or also can be as shown in Figure 6, adopt the mode forming lower electrode layer 14 and top electrode layer 13 in the upper and lower surface of a base material 38.
Or, also can be the structure shown in Fig. 7 (a) (b).Fig. 7 (a) is partial top view, eliminates the insulation course etc. shown in (b).In addition, Fig. 7 (b) be along Fig. 7 (a) A-A line cut off and the partial, longitudinal cross-sectional observed from the direction of arrow.In Fig. 7 (a) (b), at the multiple electrode layer 50,51 of the surface alignment of a base material 38, wherein towards X-direction connecting electrode layer 50, and on linking part 52 by insulation course 53 coated electrode layer 50.Further, insulation course 53 being formed the linking part 54 for connecting each electrode layer 51, via linking part 54, each electrode layer 51 being connected in the Y direction.In the structure of Fig. 7, the similar face of identical base material 38 is formed with the electrode layer 50 connected in the X direction and the electrode layer 51 be connected in the Y direction.
