In a portable device or the like, a substrate, an electrode pattern, and an insulating layer of the touch panel are formed of a translucent material, and a touch panel is provided on the surface of the color liquid crystal panel.

The color liquid crystal panel has a color filter on its inner or outer surface. In the color filter, subpixels of three colors of R (red), G (green), and B (blue) are set to represent the color of an image. In a typical color filter, the subpixels of each color are rectangular and regularly arranged in the X and Y directions. The X and Y directions coincide with the extending direction of the electrode pattern of the touch panel.

In the touch panel described in Patent Document 1 and Patent Document 2, the insulating layer insulating the bridge wiring is rectangular, and each insulating layer has the edge portion parallel to the X direction and the edge portion parallel to the Y direction. If the edge portion of the insulating layer has such a shape, the edge of the insulating layer is the same as the arrangement direction of the subpixels of the color filter, and when the color display light is given, flickering of light occurs due to the edge portion of the insulating layer . Particularly, when display light of any one of three primary colors is given from the color liquid crystal panel, flickering in color tends to occur in the insulating layer portion.

Thus, in the input device described in Patent Document 3, when the display panel that gives color display light to the distribution portion is disposed by inclining the edge portion of the insulating layer with respect to the X direction, the edge portion of the sub- So that the presence of the insulating layer is not conspicuous by the color display light and the phenomenon of flickering of the light in the insulating layer portion is prevented.

However, if the insulating layer is formed by inclining the edge portion with respect to the X direction, the intersection points of the electrode layers continuing in the Y direction and the edge portions of the insulating layer are not aligned in the X direction but are displaced in the Y direction. Therefore, when the formation position of the bridge wiring is displaced in the Y direction, the possibility that a part of the bridge wiring protrudes outward from the edge portion of the insulating layer and is short-circuited to the electrode layer continuing in the Y direction increases. In order to prevent this, it is necessary to increase the area of the insulating layer. However, if the area of the insulating layer is increased, the edge portion of the insulating layer becomes more conspicuous when the color display light is applied.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method of manufacturing a semiconductor device in which the edges of an insulating layer formed under a bridge wiring layer are inclined relative to a second direction, And a second electrode layer formed on the first electrode layer so as not to be short-circuited, so that the area of the insulating layer can be further reduced.

The present invention provides an input device having a translucent first electrode layer arranged in a first direction and a translucent second electrode layer arranged in a second direction crossing the first direction on the same surface of a translucent substrate,

Wherein the first electrode layer is formed continuously in a first direction by a connecting portion, the second electrode layer is formed on both sides of the connecting portion, the insulating layer covering the connecting portion, A bridge wiring layer for conducting the second electrode layers to each other is formed,

The edge portion of the insulating layer and the edge portion of the first electrode layer are formed so as to extend from the center portion of the insulating layer to the center portion of the insulating layer, And the distance L1 between the first intersection C1 and the insulated center line O is set to be shorter than the distance L2 between the second intersection C2 and the insulated center line O However,

Wherein the bridge wiring layer formed on the insulating layer has an opposing portion that faces the first intersection point C1 in the first direction, and the opposing portion is located in the center of the center G2 of the bridge wiring layer in the first direction, Is formed at a position away from the first intersection point (C1).

The input device of the present invention can be configured such that the bridge wiring layer has a bent portion including the opposing portion and the bent portion is deformed in a direction away from the first intersection point C1.

In this case, it is preferable that the bent portion is curved in a curved line. However, the present invention may be such that the bent portion is bent with an edge portion.

The input device of the present invention is characterized in that both ends of the bridge wiring layer are connected to the second electrode layer on both sides of the connecting portion and each of the connecting portions is located on the insulating center line.

Alternatively, both ends of the bridge wiring layer are connected to the second electrode layer on both sides of the connecting portion, and the connecting portion is formed inclined with respect to the insulating center line (O).

Alternatively, the both end portions of the bridge wiring layer may be connected to the second electrode layer on both sides of the connection portion, and the tip of the connection portion may be connected to the bridge wiring layer in the first direction, Is located apart from one intersection (C1). In this case, each of the connection portions may be configured to be parallel to the insulated center line O.

In the input device of the present invention, it is preferable that the insulating layer has a short width and a long width, and the long axis extending in the long direction is inclined with respect to the second direction.

The input device according to the present invention is characterized in that a display panel is provided on the rear side of the substrate for providing display light and color filters are formed on the inner or outer surface of the display panel, And are arranged in the first direction and the second direction.

It is also effective that the subpixel is rectangular and its long side is oriented parallel to the first direction or the second direction.

In the input device of the present invention, since the edge portion of the insulating layer formed under the bridge wiring layer is directed obliquely with respect to the second direction (X direction), when the display panel for giving color display light to the distribution portion is arranged, The presence of the insulating layer is not conspicuous by the light, and the phenomenon of flickering of the light in the insulating layer portion can be easily prevented.

In addition, even if the bridge wiring layer is formed to be displaced in the first direction (Y direction), the possibility that the bridge wiring layer and the first electrode layer are short-circuited can be lowered. As a result, the area of the insulating layer can be reduced The presence of the insulating layer can be made inconspicuous.

The input device 1 shown in Figs. 1 and 2 is one in which the touch panel 10 and the display panel 20 are integrated. However, the input device 1 of the present invention includes those which are distributed only through the touch panel 10 for the purpose of being combined with the display panel 20. 1 and 2, the Y direction is the first direction and the X direction is the second direction.

The touch panel 10 constituting the input device 1 is constituted of a first electric pole row 12 and a second electric pole row 13 on the surface 11a facing the input side of one transparent substrate 11, Respectively. The light transmittance in the present specification is not limited to pure transparent, but preferably includes, for example, a total light transmittance of 80% or more.

The substrate 11 is made of a flexible film material, for example, a PET film is used. Alternatively, the substrate 11 may be formed of a resin panel or a glass substrate having a slight thickness. The first electromagnet 12 and the second electromagnet 13 are formed of a light-transmitting conductive material. The light-transmitting conductive material may be a metal oxide layer such as indium tin oxide (ITO), SnO ₂ or ZnO, a conductive nanowire layer such as silver nanowire or carbon nanowire, a thin metal layer formed of a mesh, or a conductive polymer layer.

As shown in Fig. 3, the first electrode column 12 has a plurality of first electrode layers 12a each having a rectangular or rhombic shape. The plurality of first electrode layers 12a are arranged linearly in the Y direction, and the first electrode layers 12a neighboring in the Y direction are connected by a connecting portion 12b. The first electrode layer 12a and the connecting portion 12b are integrally formed of the same conductive material.

The second electric field column 13 has a plurality of second electrode layers 13a. The second electrode layer 13a has the same shape and the same area as the first electrode layer 12a. The second electrode layer 13a is formed independently of each other so as to sandwich the connection portion 12b of the first pre-excitation column 12, and each of the second electrode layers 13a is linearly arranged in the X direction.

By using the material in which the transparent conductive material is laminated on the surface 11a of the transparent substrate 11 such as PET or glass and etching the layer of the transparent conductive material to form the first electric field line 12 and the second electric field line 12, And the columnar portion 13 is simultaneously pattern-formed. 7 shows a part of a specific pattern shape of the first electrode layer 12a and the connecting portion 12b of the first electrode column 12 and a part of the pattern shape of the second electrode layer 13a of the second electrode column 13 Respectively.

As shown in Figs. 3 and 4, an insulating layer 14 is formed on each of the connecting portions 12b of the first pre-excitation columns 12, respectively. The insulating layer 14 is formed of a novolak resin or a translucent organic insulating material such as novolac resin and acrylic resin. The insulating layer 14 is formed on the surface of the connecting portion 12b by a photolithography method or the like after the first electric column 12 and the second electric field row 13 are formed on the surface 11a of the substrate 11 As shown in FIG.

A bridge wiring layer 15 is formed on the surface of the insulating layer 14 and the second electrode layers 13a adjacent to each other in the X direction are connected to each other via the connecting portion 12b by the bridge wiring layer 15 . The bridge wiring layer 15 is formed of a laminated conductive layer of ITO / CuNi, ITO / Au or ITO / Au alloy, a laminated conductive layer of ITO / CuNi / ITO, ITO / Au / ITO, ITO / Au alloy / do. The bridge wiring layer 15 is formed thin and thin so that visual confirmation is difficult.

When the first electric pole row 12 and the second electric pole row 13 are formed of ITO, the former columns are formed of crystalline ITO, and the ITO constituting the bridge wiring layer 15 is formed of amorphous do. Therefore, the bridge wiring layer 15 can be formed by forming a thin conductive layer on the insulating layer 14 and performing selective etching.

As shown in Fig. 3, a part of the first electric train 12 connected in the Y direction by the connecting portion 12b is drawn out to the outside of the detection region as a Y lead electrode layer 16 for each column . As shown in Fig. 1, a plurality of first land portions 17 are formed at the edge of the substrate 11, and each Y lead electrode layer 16 is individually connected to the first land portion 17 have. A portion of the second pre-excitation column 13 connected in the X direction by the bridge wiring layer 15 is drawn out to the outside of the detection area as an X outgoing electrode layer 18 for each row, The second land portion 19 is connected to the second land portion 19 separately.

The surface 11a of the substrate 11 of the touch panel 10 is covered with the cover layer 2 as shown in Figs. The cover layer 2 is formed of a translucent resin such as polycarbonate or a glass plate. The cover layer 2 and the touch panel 10 are adhered via a transparent optical adhesive layer (OCA).

In the touch panel 10, an electrostatic capacitance is formed between the first electromagnet array 12 and the second electromagnet array 13. When the finger touches the surface of the cover layer 2 by the input operation, The electrostatic capacitance between the electrode layer 12a or the second electrode layer 13a and the finger is added and the total value of the electrostatic capacitance is changed.

The driving electric power is sequentially applied to the first electric column 12 for each column and the current value detected from the second electric column 13 is sequentially measured for each column so that the finger contacts the surface of the cover layer 2 The position of the operating point on the XY coordinate can be specified. Alternatively, drive power is sequentially applied to each of the second columnar columns 13 for each column, and the current value detected from the first column 12 is sequentially measured for each column, thereby specifying an operation point at which the finger is in contact .

The touch panel 10 shown in Figs. 1 and 3 has a structure in which the first electrode layers 12a constituting the first electric column 12 are arranged in a linear line in the Y direction, And the second electrode layer 13a constituting the second electrode layer 13 are arranged in a straight line in the X direction. Therefore, by sequentially applying the driving electric power to one of the front polarized waves and sequentially monitoring the current of the other polarized wave, the position on the XY coordinate at the position where the finger touches the cover layer 2 can be relatively easily It is easy to calculate.

As shown in Figs. 1 and 2, a distributing film 3 such as PET is bonded to the back of the touch panel 10 via a transparent optical adhesive layer (OCA). On the upper and lower surfaces of the distribution film 3, the ITO layer 4 is formed on the entire surface, and the ITO layer is set to the ground potential. This ITO layer 4 can reduce the influence of the drive signal of the display panel 20 on the distribution portion, and the detection operation of the touch panel 10 can be stabilized.

The display panel 20 shown in the sectional view of Fig. 2 is a color liquid crystal panel. The display panel 20 has a light guide layer 21 for backlight. Light emitted from a light source such as an LED is given to the layer above the light guide layer 21. A polarizing filter 22, a lower glass substrate 23, a lower transparent electrode 24 and an orientation layer 25 are laminated in this order on the light guide layer 21. An alignment layer 27, an upper transparent electrode 28, a color filter 29, an upper glass substrate 31 and a polarizing filter 32 are arranged in this order with a liquid crystal layer 26 interposed therebetween.

FIG. 5 shows subpixels 35R, 35G, and 35B constituting the color filter 29. FIG. The subpixel 35R is a red layer, the subpixel 35G is a green layer, and the subpixel 35B is a blue layer. The subpixels 35R, 35G, and 35B of three colors have the same shape and the same area, and a rectangular shape in which the short side is oriented parallel to the X direction and the long side is oriented parallel to the Y direction. As shown in Fig. 5, one set of three color subpixels 35R, 35G, and 35B is set, and each set is arranged in a linear array in the X and Y directions. Further, the sub-pixels 35R, 35G, and 35B may be oriented such that their long sides are parallel to the X direction.

Driving power is applied to the lower transparent electrode 24 and the upper transparent electrode 28 of the display panel 20 to control the amount of light transmitted through the liquid crystal pixel corresponding to each subpixel, Display is performed.

The color filter 29 may be formed on the outer surface of the display panel 20 above the upper glass substrate 31.

The color display light emitted from the display panel 20 is transmitted forward through the distribution film 3, the touch panel 10 and the cover layer 2, and is forwarded to give a color image to the operator. The insulating layer 14 and the bridge wiring layer 15 are formed at a plurality of points of the touch panel 10 but the bridge wiring layer 15 is formed as thin and thin as possible so that the bridge wiring layer 15 It is designed so that it does not stand out.

5 and 7, in the input device 1 of the first embodiment, the insulating layer 14 is rectangular, and two long sides 14a and 14b parallel to each other and two short sides 14c and 14d. The direction in which the long sides 14a and 14b extend is the long side direction, and the direction in which the short sides 14c and 14d extend is the short side direction. 7, the center line extending in the long-width direction of the insulating layer 14 is shown as the long axis A. The insulating layer 14 is formed such that the long axis A is inclined with respect to the XY axis and the long sides 14a and 14b and the short sides 14c and 14d are inclined with respect to the array direction of the subpixels 35R, There is an incline.

Fig. 6 shows a comparative example. The insulating layer 114 shown in the comparative example is square, and each side is in a direction parallel to the X axis and the Y axis.

6, when the color display light is given to the touch panel 10 from the display panel 20, the edge portion of the insulating layer 14 reacts so as to shine so that a large number of flickering There is a case where the stain is visually observed. In particular, the blinking is liable to be visually observed in an area for displaying an image of any one of three primary colors.

This is because the edges of the rectangular subpixels 35R, 35G and 35B are parallel to the edges of the insulating layer 114, so that the same color emitted from the subpixels in the long region in the Y direction is parallel to the sides of the insulating layer 114 The color of the same color emitted from the subpixels of the three primary colors is emphasized by the lens effect of the edges of the sides of the insulating layer 114 which is slightly curved as shown in Fig. 4 It is predicted that easy is a factor.

5 and 7, the long sides 14a and 14b and the short sides 14c and 14d of the insulating layer 14 cross the long sides of the subpixels 35R, 35G, and 35B, The color of the same color is hardly concentrated on the edge portion of the side of the insulating layer 14, and as a result, the area where the color image is displayed, particularly, the area where the three primary colors are displayed The flickering will not occur.

When the insulating layer 14 has a line asymmetric shape with respect to both the X axis and the Y axis, it is easy to prevent the flicker. 5 and 7, by making the insulating layer 14 rectangular and inclining the long axis A with respect to the X axis, it is possible to further emphasize the linear symmetry of the insulating layer 14 with respect to the XY axis And the effect of preventing the flickering can be enhanced. By making the insulating layer 14 rectangular, the short sides 14c and 14d can be shortened, and the edge portions of the sides of the insulating layer 14 can be made more inconspicuous.

In Fig. 7, the center of gravity (center of gravity) of the insulating layer 14 is indicated by G1, and the straight line extending in the X direction beyond the center G1 is taken as the insulating center line O. [

7, in order to emphasize the line asymmetry with respect to the X axis and the Y axis of the insulating layer 14, the shape of the insulating layer 14 is rectangular and the long sides 14a and 14b are formed with respect to the X axis The first intersection C1 where the edge portion of the long side 14a and the edge portion of the first electrode layer 12a intersect and the edge portion of the short side 14c cross each other at the Y1 side with the insulating center line O as a boundary, And the second intersection C2 where the edge portions of the first electrode layer 12a cross each other can not be arranged in the X direction. That is, the distance L1 between the first intersection C1 and the insulation center line O in the first direction (Y direction) is larger than the distance L2 between the second intersection C2 and the insulation center line O in the same direction ). This is also true for the Y2 side with the insulating center line O as a boundary.

Therefore, when the bridge wiring layer 15 is formed to be displaced in the first direction (Y1 direction or Y2 direction) due to etching tolerance or the like, a part of the bridge wiring layer 15 is closer to the Y1 side than the first intersection C1, So that the possibility of shorting to the first electrode layer 12a is increased. Thus, in the first embodiment, the bridge wiring layer 15 has the shape shown in Fig.

In Fig. 7, the center G2 of the bridge wiring layer 15 coincides with the center G1 of the insulating layer 14. The bridge wiring layer 15 has a stripe shape having a sufficiently large dimension than the step size. The bridge wiring layer 15 has a rotational symmetrical shape of 180 degrees with respect to the center G2 but has a line asymmetric shape with respect to the X axis and the Y axis (with respect to the insulating center line O).

The end portion of the bridge wiring layer 15 on the X1 side is the connection portion 15a and the end portion on the X2 side is the connection portion 15b. As shown in Fig. 4, the connecting portion 15a is electrically connected to the second electrode layer 13a on the X1 side, and the connecting portion 15b is electrically connected to the second electrode layer 13a on the X2 side. The connecting portions 15a and 15b are linear in the X direction and the connecting portions 15a and 15b are insulated when the center G2 of the bridge wiring layer 15 coincides with the center G1 of the insulating layer 14. [ And coincides with the center line (O).

The bridge wiring layer 15 includes a first opposing portion 15c opposing in the first direction (Y direction) to the first intersection C1 located on the Y2 side on the X1 side and a first opposing portion 15c opposing the first opposing portion 15c located on the Y1 side on the X2 side And a second opposing portion 15e opposed to the first intersection C1 in the first direction (Y direction). The first opposing portion 15c and the second opposing portion 15e are located in a region overlapping with the insulating layer 14. The bridge wiring layer 15 is formed with a first bent portion 15d including the first opposing portion 15c and a second bent portion 15f including the second opposing portion 15e.

The first bent portion 15d is curved away from the first intersection C1 located on the Y2 side from the X1 side and the first opposing portion 15c is curved away from the center G2 Is located away from the intersection (C1) of the X1 side. The second bending portion 15f is curved away from the first intersection C1 located on the Y1 side on the X2 side and the second opposing portion 15e is curved away from the center G2 And is located away from the intersection C1 on the X2 side.

The "bend" in the first bend section 15d and the second bend section 15f is a curved shape in which the long side changes into a curved line such as an arc shape as in the embodiment of FIG. 7, And has a corner portion and a bent shape. However, it is preferable that all the long sides of the bridge wiring layer 15 are formed of curved lines, and no corner portions exist. By not forming the corner portion, when the color display light is applied to the bridge wiring layer 15 from the distribution portion, it is possible to avoid that the display light is reflected on the corner portion and is visually observed.

8 shows that the bridge wiring layer 15 is shifted toward the Y1 side due to the tolerance in the etching process and the center G2 of the bridge wiring layer 15 is moved to the Y1 side of the center G1 of the insulating layer 14 Respectively.

Assuming that the bridge wiring layer 15 is formed in a straight line in the X direction as shown by the broken line in Fig. 8, if the bridge wiring layer 15 is formed at the position shown in Fig. 8, A part thereof protrudes from the Y1 side of the first intersection C1 on the X2 side and shorts to the first electrode layer 12a.

On the contrary, in the first embodiment, the second bent portion 15f formed in the bridging wiring layer 15 in the shape of a protruding curve toward the direction away from the first intersection C1 on the X2 side is formed, and the second bent portion 15f 15f are located apart from the first intersection C1 on the X2 side toward the Y2 side. Therefore, even if the bridge wiring layer 15 is displaced as shown in Fig. 8, the probability that the bridge wiring layer 15 is short-circuited to the first electrode layer 12a can be reduced.

Similarly, when the bridge wiring layer 15 is formed to be displaced in the Y2 direction so that the center G2 is moved to the Y2 side from the center G1, the first bent portion 15d is formed in a protruded curve toward the Y1 direction Therefore, the bridge wiring layer 15 is not short-circuited to the first electrode layer 12a.

As a result, the short sides 14c and 14d of the rectangular insulating layer 14 can be shortened, and the flickering due to the edge portions of the insulating layer 14 by the color display light can be prevented more effectively .

In the present invention, the shape of the bridge wiring layer 15 can be modified as in the second embodiment shown in Fig.

In the second embodiment shown in Fig. 9, the connecting portion 15a and the second connecting portion 15b of the bridge wiring layer 15 are formed inclined with respect to the insulating center line O.

If the first intersection C1 is closer to the insulation center line O than the second intersection C2 in the intersection between the edge of the insulating layer and the edge of the first electrode layer 12a, Pattern may be formed. For example, as in the third embodiment shown in Fig. 10, the insulating layer 114 is formed such that each corner portion of a rectangle having a rectangular or square shape has a protruding curved shape such as an arc, and the long axis A1 thereof has an insulating center line O As shown in Fig.

Fig. 11 shows an input device according to the fourth embodiment of the present invention.

The bridge wiring layer 15 shown in Fig. 11 has a linear portion 15g including the center G2 on the insulating layer 14, and the straight portion 15g is inclined with respect to the insulating center line O Respectively. The first opposing portion 15c and the second opposing portion 15e are located in the straight line portion 15g and the first opposing portion 15c extends from the first intersection C1 located on the Y1 side to the Y1 side As shown in Fig. Likewise, the second opposing portion 15e is formed at a position away from the first intersection C1 located on the Y1 side on the X2 side.

That is, each of the opposing portions 15c and 15e is formed at a position away from the first intersection C1 than the center G2 of the bridge wiring layer 15 in the first direction (Y direction).

The bridge wiring layer 15 has connecting portions 15a and 15b on both sides of the straight line portion 15g. The boundary between the straight line portion 15g and the connection portion 15a is the first bent portion 15d and the boundary portion between the straight line portion 15g and the connection portion 15b is the second bent portion 15f. The first bend section 15d and the second bend section 15f are curved.

The connecting portion 15a and the connecting portion 15b extend parallel to the insulating center line O. The connecting portion 15a and the connecting portion 15b extend parallel to the insulating center line O. However, And is located on the Y1 side with respect to the center line O. The tip end 15b1 of the connecting portion 15b is located on the Y2 side of the insulating center line O so as to be further away from the center G2 than the first intersection C1.

In the fifth embodiment shown in Fig. 12, the bent portions 15h and 15i formed in the bridge wiring layer 15 are bent with corner portions. As described above, it is preferable that the bent portions are curved. In each of the above-described embodiments, the bent portions 15h and 15i having corner portions may be formed as shown in Fig.

Further, in the present invention, the display panel may be an electroluminescence panel or an organic electroluminescence panel, and the subpixels 35R, 35G, and 35B may be pixels of the electroluminescence panel. In this case, the same effect can be obtained.
