If the first detection electrode 3a and the second detection electrode 4a have a substantially rhombus shape in plan view, the gap between the first detection electrode 3a and the second detection electrode 4a can be narrowed. For this reason, the area of the 1st detection electrode 3a provided on the main surface 2a of the base | substrate 2 and the 2nd detection electrode 4a can be enlarged relatively. Therefore, the electrostatic capacitance generated between the first detection electrode 3a and the second detection electrode 4a and the finger F1 can be increased, and the detection sensitivity of the input device X1 is improved.

Specifically, as shown in FIG. 5, the protective member 7 is provided so as to protrude outward from the end surface 2 b of the base 2. Note that the protective member 7 may be located on the inner side of the end surface 2 b of the base 2.

  Further, the back surface 7 b of the protection member 7 is bonded to the main surface 2 a of the base 2 via the adhesive material 8.

Here, as shown in FIGS. 1, 2, and 5, the first light shielding film 9 is provided on the back surface 7b of the protective member 7 corresponding to the non-input area E2. The first light shielding film 9 has a role of shielding light incident in a direction intersecting with the main surface 2 a of the base 2. In this specification, “light shielding”
By means of reflection or absorption is meant to block visible light. In the present embodiment, as shown in FIG. 2, the first light shielding film 9 is provided on the back surface 7 b of the protection member 7 so as to overlap the plurality of detection wirings 6 in plan view. In this specification, “so as to overlap with the plurality of detection wirings 6 in plan view” may overlap with all of the plurality of detection wirings 6 in plan view, or a plurality of detection wirings 6 in plan view. This means that it may overlap with a part of the detection wiring 6. Since the 1st light shielding film 9 is provided on the back surface 7b of the protection member 7, possibility that the wiring 6 for a detection will be visually recognized by a user can be reduced.

  In the present embodiment, the first light shielding film 9 is provided over the entire back surface 7b of the protective member 7 corresponding to the non-input area E2, but the present invention is not limited to this. That is, if the possibility that the detection wiring 6 is visually recognized by the user can be reduced, the first light shielding film 9 is provided on a part of the back surface 7b of the protective member 7 corresponding to the non-input area E2. May be.

  Moreover, although the 1st light shielding film 9 demonstrated above the example provided on the back surface 7b of the protection member 7 corresponding to the non-input area E2, it is not restricted to this. In other words, the first light shielding film 9 may be provided on the operation surface 7a of the protection member 7 corresponding to the non-input area E2. However, when the first light-shielding film 9 is provided on the back surface 7b of the protection member 7 as in the present embodiment, the operation surface 7a of the protection member 7 can be made substantially flat, and the input device X1 design is improved.

  Examples of the constituent material of the first light shielding film 9 include a resin material containing a coloring material. Examples of the resin material include acrylic resin, epoxy resin, silicon dioxide, and the like. Examples of the coloring material include carbon, titanium, and chromium. The first light shielding film 9 is not limited to black, and may be colored other than black. Examples of the method for forming the first light shielding film 9 include a screen printing method, a sputtering method, a CVD method, a vapor deposition method, and the like.

  Further, as shown in FIG. 5, an insulating film 10 and a second light shielding film 11 are provided on the main surface 2a of the base 2 corresponding to the non-input area E2.

  The insulating film 10 has a role of protecting the detection wiring 6 from corrosion due to moisture absorption. For this reason, the insulating film 10 covers the detection wiring 6. In the present embodiment, the insulating film 10 covers all of the plurality of detection wirings 6. The insulating film 10 also has a role of electrically insulating the detection wiring 6 and the second light shielding film 11. Examples of the constituent material of the insulating film 10 include acrylic resins, epoxy resins, or transparent resins such as silicon dioxide and silicon nitride. Examples of the method for forming the insulating film 10 include a transfer printing method, a spin coating method, and a slit coating method.

  The second light shielding film 11 has a role of shielding light incident in a direction intersecting with the main surface 2 a of the base 2. The second light shielding film 11 also has a role of protecting the insulating film 10 from corrosion due to moisture absorption. For this reason, the second light shielding film 11 covers the insulating film 10. As a constituent material and a forming method of the second light shielding film 11, the same materials as those of the first light shielding film 9 are exemplified. The second light shielding film 11 may be formed by coloring a color different from that of the first light shielding film 9.

Here, suppose that the second light shielding film 11 as described above is not provided as in the conventional input device. In this case, for example, when the user looks into the input area from an oblique direction, the detection wiring positioned on the input area side among the plurality of detection wirings may be visually recognized by the user. In order to reduce the possibility that the detection wiring will be visually recognized by the user, even if the user looks into the input area from an oblique direction, the detection wiring is not input to the user so that the detection wiring is not visible to the user. It is necessary to arrange it some distance away. That is, as shown in FIG. 5, the distance L1 between the end 9a on the input region E1 side of the first light shielding film 9 and the detection wiring 6a located on the input region E1 side among the plurality of detection wirings 6 is set large. There is a need to. However, in this state, the non-input area of the input device becomes large, and the input device becomes large in the lateral direction.

  On the other hand, in the input device X1, the second light shielding film 11 is provided on the main surface 2a of the base 2 so as to cover at least the detection wiring 6a located on the input region E1 side among the plurality of detection wirings 6. It has been. In this specification, “covering the detection wiring 6 a” does not need to cover the entire detection wiring 6 a, and may mean that a part of the detection wiring 6 a may be covered. Further, “covering the detection wiring 6a” does not need to cover the detection wiring 6a directly, and may mean that the detection wiring 6a may be covered indirectly. In the present embodiment, the second light shielding film 11 covers the insulating film 10. Therefore, for example, even if the user looks into the input area E1 from an oblique direction, the second light shielding film 11 allows the user to visually recognize the detection wiring 6a positioned at least on the input area E1 side among the plurality of detection wirings 6. It is possible to reduce the possibility of being done. Further, in the input device X1, the second light shielding film 11 is provided so as to cover at least the detection wiring 6a located on the input region E1 side among the plurality of detection wirings 6, so that L1 shown in FIG. It becomes possible to set small.

  In the above description, the second light shielding film 11 covers the insulating film 10. However, the present invention is not limited to this. For example, as shown in FIG. 6, the second light shielding film 11 may cover a part of the insulating film 10. That is, if the second light shielding film 11 is provided on the main surface 2a of the base body 2 so as to cover at least the detection wiring 6a located on the input region E1 side among the plurality of detection wirings 6, the second light shielding film. The shape, position, etc. of the film 11 are not particularly limited. Further, for example, as shown in FIG. 7, the first light shielding film 9 and the second light shielding film 11 may be connected to each other. In this case, the thickness of the first light shielding film 9 or the second light shielding film 11 is increased, and the adhesive material 8 does not exist between the first light shielding film 9 and the second light shielding film 11. The possibility that 6 will be visually recognized by the user can be further reduced. Further, for example, as shown in FIG. 8, the end 9a on the input area E1 side of the first light shielding film 9 may be located outside the detection wiring 6a located on the input area E1 side.

    Next, the detection principle of the input device X1 will be described.

  A position detection driver (not shown) is electrically connected to the detection wiring 6 located in the external conduction region G1. The position detection driver includes a power supply device. The power supply device of the position detection driver supplies a voltage to the first detection electrode pattern 3 and the second detection electrode pattern 4. Here, when the finger F1, which is a conductor, approaches the main surface 2a of the base 2 corresponding to the input region E1 via the protective member 7, the gap between the finger F1 and the first detection electrode 3a and the second detection electrode 4a is reached. Capacitance is generated at. The position detection driver always detects the capacitance generated in the first detection electrode pattern 3 and the second detection electrode pattern 4, and the first detection electrode pattern 3 and the second detection electrode 2 that have detected a capacitance greater than a predetermined value. The combination of the detection electrode patterns 4 detects the input position where the user has performed an input operation. In this way, the input device X1 can detect the input position.

  As described above, in the input device X1, it is possible to reduce the size while reducing the possibility that the detection wiring 6 is visually recognized by the user.

Examples of the constituent material of the first housing 103 include a resin such as polycarbonate or a metal such as stainless steel or aluminum.

  Here, the input device X1 and the liquid crystal display device Z1 are bonded via a double-sided tape 104. That is, the input device X1 and the liquid crystal display device Z1 are provided with the double-sided tape 104 so that the surface of the input device X1 opposite to the main surface 2a of the base 2 is disposed to face the main surface of the liquid crystal panel 101. Is glued through. Note that the fixing member used in the fixing method between the input device X1 and the liquid crystal display device Z1 is not limited to the double-sided tape 104. For example, an adhesive member such as a thermosetting resin or an ultraviolet curable resin, or the input device X1. And a fixed structure that physically fixes the liquid crystal display device Z1. Further, the input device X1 and the liquid crystal display device Z1 may be disposed in contact with each other or may be disposed with a gap therebetween.

  Thus, the input device X1 can input various information by performing an input operation on the input area E1 of the input device X1 while seeing through the liquid crystal panel 101 of the liquid crystal display device Z1. When inputting various types of information, the input device X1 may be provided with a function of presenting various tactile sensations such as a feeling of pressing, a feeling of tracing, and a feeling of touch to the user who has input the information. In this case, the base body 2 in the input device X1 includes one or more vibrating bodies (for example, piezoelectric elements), and when a predetermined input operation or a predetermined pressing load is detected, the vibrating body is detected at a predetermined frequency. It can be realized by vibrating.

  Since the display device Y1 includes the input device X1, it is possible to reduce the size while reducing the possibility that the detection wiring 6 is visually recognized by the user.

  Next, the portable terminal P1 provided with the display device Y1 will be described with reference to FIG.

  In addition, the mobile terminal P1 may include a short-distance wireless communication unit such as a digital camera function unit, a one-segment broadcasting tuner, an infrared communication function unit, and various interfaces, depending on the required functions. The detailed illustration and description thereof will be omitted.

  Since the portable terminal P1 includes the display device Y1, it is possible to reduce the size while reducing the possibility that the detection wiring 6 is visually recognized by the user.

  In addition, although the example which provided the audio | voice input part 201 in the portable terminal P1 was demonstrated above, it is not restricted to this. That is, the voice input unit 201 may not be provided in the mobile terminal P1.

  Moreover, although the portable terminal P1 demonstrated the example provided with the 2nd housing | casing 204 which accommodates the display apparatus Y1, the audio | voice input part 201, the audio | voice output part 202, and the key input part 203 above, it is not restricted to this.
