In the present embodiment, electrode 3 comprises: multiple electrode units 30, and longitudinally (Y-direction) arranges; And electrode connecting line 31, be electrically connected adjacent electrode unit 30.Multiple electrode units 30 are formed as mesh-shape by multiple wires 5 are intersected.The profile of electrode unit 30 is formed as rhombus, but the profile of electrode unit 30 is not limited to rhombus, as long as can detect the contact point of finger etc., can be arbitrary shape.In addition, the pattern form of electrode 3 can be not only, by electrode connecting line 31, multiple electrode units 30 with regulation shape are connected into the shape that linearity obtains, and can be also the rectangle shown in Fig. 2.In addition, electrode 3 neither be formed as mesh-shape by multiple wires 5, as shown in Figure 3, can be also only will longitudinally (Y-direction) wire 5 of extending along horizontal structures of (directions X) arrangements.In addition, in Fig. 3, wire 5 is formed as Z-shaped (serrate) of the shape as the tooth of saw, but also can be formed as straight linearity.
Electrode connecting line 31 interconnects the wire 5 of adjacent electrode unit 30, between adjacent electrode unit 30, is provided with one or more.The shape of electrode connecting line 31 can be the rectilinear form extending along a direction, also can be shape in a position or the bending of multiple positions (L shaped, Z-shaped etc.), but preferably, by shape and the radical of electrode connecting line 31 are suitably set, while making the electrode 3 extending longitudinally and the electrode 3 extending transversely intersect in the time forming contact panel, make the cross section of two electrodes 3 be formed as in appearance mesh by electrode connecting line 31.Therefore, because the mesh of the mesh of described cross section and the electrode unit 30 of each electrode 3 is similarly arranged, can make the global shape of the electrode 3 of observing from a face side of base material become uniform mesh-shape pattern, so can make the pattern form of electrode 3 become not eye-catching, its result, can improve the sharpness of contact panel.In addition, mesh-shape not only comprises that the line such as wire 5 and electrode connecting line 31 is also comprising the mode of intersecting to have the mode of intersection point in apparent situation with line, is also included within the part that line intersects and is interrupted the mode that makes line and line not have intersection point to intersect because of at least one party's line.Electrode connecting line 31 can be formed by the material identical from the wire 5 of electrode unit 30, also can be formed by the material different with the wire 5 of electrode unit 30, but owing to using the material identical with wire 5 to be formed on a face side of base material 2, can form efficiently electrode connecting line 31, so be preferred.
As shown in Figure 4, on wire 5 and at least one party's alongst lateral edges 50A, I spaced apart is provided with multiple recesses 51, forms described recess 51 by wire 5 being cut to a part.Wire 5, by being provided with recess 51, can make the live width W part of wire 5 attenuate, and compared with recess 51 ground are not set are formed as the situation of fixed line width W0, has improved the light penetration of wire 5 (electrode 3).In addition, due to by recess 51 is set, make the reflection light diffusing of the lateral edges of wire 5, so be difficult to see from outside electrode 3.In addition, in order to improve the effect of reflection light diffusing of lateral edges of described wire 5, preferably, on wire 5, form with high density the recess 51 that multiple width L are little.The live width W0 of described wire 5 represents not exist the original live width of the wire 5 of recess 51 that is the distance from wire 5 one sides' lateral edges 50A to the opposing party's lateral edges 50B.
There is no particular limitation for the shape of recess 51, except the elliptical shape shown in Fig. 4 (shape of the mode bending that comprises a part of describing oval arc), also trapezoidal shown in the rectangle shown in the semi-circular shape shown in Fig. 5 (shape of the mode bending that comprises a part of describing circular arc), Fig. 6, the triangle shown in Fig. 7, Fig. 8 can be formed as, and the various shapes such as polygon can be formed as.In addition, as shown in Figure 9, part or all that also can make recess 51 self becomes convex-concave 52.
In the present embodiment, on two lateral edges 50A, 50B of wire 5, the recess 51 of the lateral edges 50A that is respectively arranged with multiple recess 51, one sides spaced apart is arranged alternately along the length direction of wire 5 with the recess 51 of the opposing party's lateral edges 50B.As shown in figure 10, in the time being provided with recess 51 on the lateral edges 50A a side of wire 5 only, because the live width W of part between the recess 51 of wire 5 can not attenuate, so due to the depth D of the recess 51 of the live width W0 original with respect to wire 5, there is the part of recess 51 and do not having the part between the recess 51 of recess 51, live width W significantly changes, and exists the part that local live width W is large, this part likely to become eye-catching on wire 5.With respect to this, by making recess 51 alternate configurations on two lateral edges 50A, 50B of wire 5, between two adjacent recesses 51 of a side lateral edges 50A, dispose the recess 51 of the opposing party's lateral edges 50B, can make the live width W of part between described recess 51 also attenuate, the cardinal principle total length that therefore can spread all over wire 5 attenuates live width W.In addition, owing to equably wire 5 being cut to a part by recess 51 from two lateral edges 50A, 50B, so the shape of wire 5 can not be out of shape, thereby can prevent owing to there is recess 51 sharpness of contact panel to produce harmful effect.
When recess 51 being arranged on to two lateral edges 50A, 50B of wire 5 when upper, as shown in Figure 4, recess 51 Local Phases of the recess 51 of one side's of wire 5 lateral edges 50A and the opposing party's lateral edges 50B are to (repetition), specifically, preferably configure as follows 51: one sides' of each recess the recess 51 of lateral edges 50A and two recesses 51 of the opposing party's who is clipped in the middle the lateral edges 50B part 53 relative (repetition) in Width both sides.Thus, can make the live width W of wire 5 become thinner.In addition, in Fig. 6, Fig. 8 and Fig. 9, as shown in Figure 4, the recess of a side's of wire 5 lateral edges 50A 51 with recess 51 Local Phases of the opposing party's lateral edges 50B to (repetitions), but neither relative (repetition).On the other hand, in Fig. 5 and Fig. 7, different from Fig. 4, the recess 51 not relative (repetition) of the recess 51 of a side's of wire 5 lateral edges 50A and the opposing party's lateral edges 50B, but also can make their Local Phases to (repetition).
If the live width W of wire 5 is attenuated, can improve light penetration, and can make wire 5 become not eye-catching, but on the other hand, if make live width W become meticulous, have the problem such as broken string, be not only used in the processing that forms recess 51 on wire 5 and become difficulty, also existence makes the resistance value of wire 5 become large problem.Therefore, the thinnest part of the live width W of wire 5 is more than 3 μ m, the thickest part is below 50 μ m,, the live width W of wire 5 is preferably in the scope more than 3 μ m and below 50 μ m, more preferably in the scope more than 3 μ m and below 25 μ m, further preferably in the scope more than 3 μ m and below 10 μ m.
There is no particular limitation for the interval I of adjacent recess 51, due to interval, I is less, the cardinal principle total length that can spread all over wire 5 attenuates live width W, so be preferred, arrange the processing that forms recess 51 and becomes difficulty but I little meeting in interval is used at lateral edges 50A, the 50B of wire 5.On the other hand, if the interval I of adjacent recess 51 is large, due to as described above between recess 51 part live width W can not attenuate (particularly as shown in figure 10, while only recess 51 being set on a side's of wire 5 lateral edges 50A), on wire 5, there is the wider part of local live width W, thereby cause wire 5 likely to become eye-catching.Therefore,, compared with the width L of recess 51 described later, the interval I of adjacent recess 51 is preferably more than 0.5 × L and below 5 × L, more preferably more than 0.5 × L and below 2 × L.In addition, the interval I of adjacent recess 51 refers to the distance between the end of the Width both sides of adjacent recess 51 on lateral edges 50A, the 50B of wire 5.
The width L of recess 51 is not particularly limited, due to width, L is larger, and the cardinal principle total length that can spread all over wire 5 makes the quantity that recess 51 is set tail off and can make live width W attenuate, so be preferred, if but width L is excessive, self attenuating to become with wire 5 does not have difference.On the other hand, if width L is too small, need wire 5 to form multiple recesses 51 with high density, form the processing of recess 51 and become difficulty thereby be used in.Therefore, compared with the live width W0 original with wire 5, the width L of recess 51 is preferably more than 0.5 × W0 and below 10 × W0, more preferably more than 0.5 × W0 and below 5 × W0.In addition, the width L of recess 51 refers to the distance between the both ends of the Width of recess 51 on lateral edges 50A, the 50B of wire 5.
The depth D of recess 51 is not particularly limited, if but depth D is excessive, there is the problems such as broken string, and be used in the processing that forms recess 51 on wire 5 and become difficulty, and particularly in the time that the original live width W0 of wire 5 is wider, because making the depth D of recess 51 become large, there is the part of recess 51 and do not having the part of recess 51, live width W significantly changes, and existence causes on wire 5, having the wide part of local live width W and makes wire 5 become eye-catching problem.On the other hand, if depth D is too small, also can not make live width W become very thin even if recess 51 is set, existence can not improve the problem of the light penetration of wire 5 effectively.Therefore, the depth D of recess 51 is preferably set for and is less than 50% of the original live width W0 of wire 5.But, need to set for: more than making the residual 3 μ m of live width W of the wire 5 after recess 51 forms.In addition, the depth D of recess 51 refers to the distance from lateral edges 50A, the 50B of wire 5 to recess 51 deeps.
Form multiple width L, interval I and depth D is designed in the recess 51 in described scope by the wire 5 for live width W0, can suitably design recess 51 ratio shared with respect to wire 5.Describe as an example of Fig. 4 example, for example, for the wire 5 of live width W0=10 μ m, form the semiellipse shape recess 51 of multiple width L=20 μ m, interval I=10 μ m, depth D=5 μ m, (in this case recess 51 and interval occur that the area of the recess 51 in the area of length (90 μ m)) of three is 52% degree to the datum length of each wire 5 repeatedly.
Recess 51 can be formed as identical shape, in addition, also can comprise different shapes, but the shape of wire 5 can not be out of shape when being formed as whole same shape, and can form efficiently recess 51, so be preferred.In addition, same shape is that the major part that comprises recess 51 shapes is the concept of identical shape, as shown in Figure 11 and Fig. 4 are compared, a part 53 for recess 51 Width both sides than design (Fig. 4) broaden etc. such, while causing shape different slightly because of the deviation on manufacturing, also as substantially identical and be included in same shape.
The wire 5 of described structure for example will comprise gold by (1), silver, copper, platinum, palladium, carbon, tin indium oxide (ITO), mixed oxidization zinc obtains in indium oxide electroconductive oxide (IZO[indium zinc oxide (indiumzinc oxide)]), or the method (with reference to Japanese Patent Publication communique JP 2007-142334 etc.) of the conductive paste serigraphy of the atomic little conductive particle of the electroconductive oxide that hybrid silica obtains in indium oxide (ITSO) etc. on base material 2, or (2) after the metal foil layers such as copper are stacked on base material 2, in metal forming, form corrosion-resisting pattern, and metal forming is carried out to etching method (with reference to Japanese Patent Publication communique JP 2008-32884 etc.) etc., first on base material 2, form the wire 5 with regulation live width W0.In addition, the method that forms the wire 5 with regulation live width W0 on base material 2 is not limited to the method for described (1), (2), also can use described (1) the known print process such as intaglio printing or ink jet printing or described (2) photoetching process in addition in addition.In addition, preferably, form electrode connecting line 31 and wiring 4 by described method together with wire 5.
Can in forming described wire 5, form the recess 51 of lateral edges 50A, 50B.For example, by wire 5 irradiating lasers to the live width W0 forming by described method, lateral edges 50A, the 50B of wire 5 are cut to convex, remove the wire 5 of this part with physics mode.Thus, on lateral edges 50A, the 50B of wire 5, form recess 51, by recess 51, form the live width W wire 5 thinner than original live width W0.In order to remove wire 5, for example, can use YAG laser etc.As shown in the embodiment, in the time electrode 3 being formed as to mesh-shape by multiple wires 5, form recess 51 for all conducting 5 intersecting (wire 5, extending along all directions).In addition, preferably, the intersection point portion of intersecting at wire 5 does not arrange recess 51 as far as possible.In addition, preferably, by not only forming recess 51 for wire 5 but also for electrode connecting line 31 and wiring 4, can make live width thinner than original live width.
According to the electroded transparent planar substrate 1 of present embodiment, owing to forming cancellous electrode 3 by multiple wires 5 are intersected, so compared with situation about using ITO as electrode material, can realize the low resistance of the electrode 3 being formed on base material 2.In addition, because the wire 5, electrode connecting line 31 and wiring 4 graph thinning that make to form electrode 3 by recess 51 make them become desirable thickness, so can effectively improve the light penetration of electrode 3, in addition, because pattern form and the wiring 4 that can effectively make electrode 3 become not eye-catching, so can improve the sharpness of contact panel, thereby can be advantageously applied to capacitance type touch-control panel.In addition, owing to making their graph thinning by recess 51 being set at the lateral edges of wire 5, electrode connecting line 31 and wiring 4, even so do not form the thin wire of live width 5, electrode connecting line 31 and wiring 4 at first, also can make described line attenuate as desirable thickness.If form at first the thin wire of live width 5, electrode connecting line 31 and wiring 4, the thickness of line and shape are unstable, and likely broken string, but in the present embodiment, owing to can forming wire 5, electrode connecting line 31 and the wiring 4 of stable thickness and shape, so can improve the throughput rate of electroded transparent planar substrate 1 and contact panel.
Above, an embodiment of the present utility model is illustrated, but embodiment of the present utility model is not limited to described embodiment.For example, can be in the gap of adjacent electrode 3 by using the wire substantially equating with the live width of described wire 5 to form and the electric independently cancellous dummy pattern of electrode 3, it is not eye-catching that thereby the pattern form that makes electrode 3 becomes, also can, by also forming recess 51 on the wire forming described dummy pattern, similarly make wire graph thinning.
In addition, in said embodiment, wire 5, electrode connecting line 31 and the wiring 4 of electrode 3 are straight linearity, but the wire 5 of electrode 3, electrode connecting line 31 and wiring 4 can be also the various shapes such as the serrate of the such shape of the waveform of the such shape of wave or the tooth of saw.
In addition, in said embodiment, electrode 3 is formed as to band shape and the electrode of multiple band shapes that are arranged side by side 3, but also can as shown in figure 12, electrode 3 be formed as to island, and arrange in length and breadth the electrode 3 of multiple islands.In the time that electrode 3 is formed as to island, 4 be connected with each electrode 3 owing to making respectively to connect up, so a part for wiring 4 is configured between each electrode 3.In this embodiment, can be by making multiple wires 5 intersect and electrode 3 is formed as to mesh-shape, and make their graph thinning by form recess 51 in wire 5 and wiring 4.In addition, in the embodiment of Figure 12, only just possesses the function as contact panel by the electroded transparent planar substrate 1 with island electrode 3.
