  The present invention relates to an input device in which a plurality of translucent electrode layers are formed on a translucent substrate.

  A portable electronic device or the like is provided with an input device for detecting a capacitance, and the input device is disposed in front of a display panel such as a color liquid crystal panel.

  In the input device, a plurality of light transmitting electrode layers are formed on a light transmitting substrate, and the electrode layers are connected in a second direction to a first electrode layer connected in a first direction. And a second electrode layer. When driving power is applied to one of the first electrode layer and the second electrode layer, a detection output is obtained from the other electrode layer, and it is determined where in the input device a finger or the like is approaching. It will be able to detect.

  In this type of input device, there are devices in which both the first electrode layer and the second electrode layer are formed on the same surface of one substrate so that the number of substrates can be reduced for thinning.

  In this input device, the first wiring layer (lead layer) connected to the first electrode layer, and the second wiring layer (lead layer) connected to the second electrode layer are provided on the surface of the substrate. The first electrode layer is connected in the first direction and the second electrode layer is connected in the second direction. It is necessary to route at the edge in the direction 1 and route the second wiring layer at the edge in the second direction of the substrate. If the wiring area is formed on two mutually orthogonal sides of the substrate, this wiring area becomes a dead area which does not function as a detection area. In addition, when the input device is attached to the front panel, it is necessary to cover the wiring area with the decorative layer, and there is a problem that the display area of the display panel is narrowed by the provision of the decorative layer.

  In the touch screen panel described in Patent Document 1, a second sensing pattern continuous in the Y direction and a second connection pattern connecting the second sensing electrodes in the Y direction are integrally formed, and both sides of the second connection pattern are formed. The first sensing electrodes aligned in the X direction are formed independently of each other. Also, a drive pattern extends continuously between the first sensing electrode and the second sensing electrode in the Y direction. The second connection pattern and the drive pattern are covered with the insulating layer, and the first sensing electrodes adjacent in the X direction are connected to each other by the first connection pattern formed on the insulating layer.

  In the touch screen panel, when the drive pattern passes below the first connection pattern, a drive wire connected to the second sensing electrode, and a drive wire connected to the first sensing electrode via the drive pattern. Can be drawn only to the edge of the substrate facing in the Y direction.

  In the touch panel described in Patent Document 2, a plurality of first electrodes aligned in the X direction and a first conductive wire connecting the first electrodes are integrally formed on the surface of a substrate. An opening is formed in each first electrode, and second electrodes are formed independently of each other in the opening. An insulating layer is formed on the first electrode, and a second conducting wire is formed on the insulating layer, and adjacent second electrode layers in the Y direction are connected by the second conducting wire.

  The surface of the substrate is provided with conductive segments extending in the Y direction, and each conductive segment is connected to the first conductive wire, but at the intersection between the first conductive wire and the conductive segment, which should not be connected: The insulating layer is formed on the surface of the first conducting wire, and the conductive segments are connected to each other through a third conducting wire formed on the insulating layer.

  In this touch panel, since the conductive segment connected to the first electrode conducting in the X direction extends in the Y direction, the lead wire connected to the first electrode and the second electrode are connected The leads can be routed only to the edge of the substrate in the Y direction.

  In the touch screen panel described in Patent Document 1, the drive pattern conducted to the first sensing electrode passes a position close to the side of the second sensing electrode. Therefore, a capacitance is formed between the drive pattern and the second sensing electrode, and the opposing portion between the drive pattern and the second sensing electrode becomes a sensitivity region. When a finger or the like approaches, a detection output is generated between the drive pattern and the second sensing electrode, and this output is an original detection output that detects a change in capacitance between the first sensing electrode and the second sensing electrode. Is superimposed as detection noise.

  The touch panel described in Patent Document 2 conducts to the first electrode because the conductive segment conducting to any of the first electrodes extends in the Y direction so as to get over the other first electrodes. The problem that the conductive segment is relatively separated from the second electrode and the region not to have sensitivity originally as described in Patent Document 1 is less likely to be the sensitivity region.

  However, the touch panel described in Patent Document 2 has a special structure in which the second electrode is disposed in the opening formed in the first electrode, so the second electrodes are connected to each other. It is necessary to provide two second leads per one first electrode. Therefore, when the number of electrodes is increased, the number of second conductive lines and the number of insulating blocks formed under the second conductive lines increase, and when the display panel provided behind is displayed, the number of second conductive lines is increased. And the insulating block are easy to see, and the display quality is easily impaired.

  The present invention solves the above-mentioned conventional problems, and reduces the wiring area at the edge of the substrate so that the area of the display area (input area) can be expanded, and it is unnecessary between the wiring layer and the electrode layer. It is an object of the present invention to provide an input device capable of suppressing a phenomenon in which the sensitivity is formed and further capable of maintaining good display quality.

According to a first aspect of the present invention, a first electrode layer and a second electrode layer formed of a light-transmitting conductive material are formed on a light-transmitting substrate, and the plurality of first electrode layers An input device in which a first electrode row is formed side by side in a direction 1, and a plurality of second electrode layers are formed side by side in a second direction intersecting the first direction. In
At the intersection of the first electrode row and the second electrode row, a connecting portion for connecting any one of the first electrode layer and the second electrode layer is the light transmitting property. The first insulating layer and the first bridge connection layer are formed on the coupling portion in an overlapping manner, and the other electrode layers are electrically connected by the first bridge connection layer. Yes,
The first electrode row is disposed with a row gap portion in the second direction, and an adjacent space portion is spaced in the direction in which the first electrode layer and the second electrode layer intersect the second direction. And the wiring layer and the guard layer located on the side of the wiring layer are formed extending in the first direction in the row gap without being located in the adjacent space , The wiring layer is electrically connected to the second electrode layer.
According to a second aspect of the present invention, the first electrode row is disposed with a row gap in the second direction, and in the row gap, the sides of the first electrode layer face each other in the second direction. In the column gap portion, a wiring layer and a guard layer located on the side of the wiring layer are formed to extend between the sides of the first electrode layer in a first direction. It is characterized in that the wiring layer is electrically connected to the second electrode layer.

  In the input device of the present invention, the wiring layer connected to the second electrode layer and the guard layer are formed in the row gap portion of the first electrode row to form the electrode layer and the wiring layer on the surface of the substrate. It's easy to do. Further, by disposing the guard layer on the side of the wiring layer, it is possible to prevent an unnecessary sensitivity region from being formed between the wiring layer and the first electrode layer.

  In the input device of the present invention, the wiring layer and the guard layer are formed of the same light-transmitting conductive material as the first electrode layer and the second electrode layer, and a second conductive layer is formed on the guard layer. It is preferable that an insulating layer and a second bridge connection layer be formed, and the second electrode layer and the wiring layer be connected by the second bridge connection layer.

  For example, the guard layer is formed on both sides of the wiring layer, and the second insulating layer and the second bridge connection layer are formed on each of the guard layers on both sides.

  In the input device of the present invention, an intermediate layer integral with the wiring layer is formed in the column gap portion, and the second electrode layer is connected to the intermediate layer via the second bridge connection layer. Is preferred.

  As described above, by forming the wiring layer and the guard layer on the same surface by using the same conductive material as the first electrode layer and the second electrode layer, it is not necessary to separately form the wiring layer and the guard layer. In addition, since the second bridge connection layer may be formed mainly limited to the portion covering the guard layer, the formation location and formation area of the insulating layer and the bridge connection layer can be reduced, and the display quality is unlikely to be impaired. .

  In the input device of the present invention, the wiring layer connected to the first electrode layer and the wiring layer connected to the second electrode layer can be routed only in the first direction. There is no need to provide a wiring area at the edge of the direction.

  Further, since the wiring layer and the guard layer connected to the second electrode layer are formed in the column gap between the first electrode column and the first electrode column, the wiring layer and the first electrode layer are formed. Can prevent the formation of a sensitivity region. In addition, the size and number of the insulating layer and the bridge connection layer can be reduced, and the display quality is unlikely to be impaired.
