Further, as shown in FIGS. 2 and 3, on the first substrate 2 on the back 2b corresponding to the input region E _I, the protective member 6 is provided.

The protection member 6 is a member that plays a role of protecting the first detection electrode 3a, the first connection electrode 3b, the second detection electrode 4a, the second connection electrode 4b, and the insulator 5. For this reason, the protection member 6 is provided so as to cover these members. That is, the protection member 6 is bonded to the back surface 2b of the first base 2 corresponding to the input area E _I through the bonding member 7. Examples of the protective member 6 include a PET (polyethylene terephthalate) film, an acrylic film, a polycarbonate film, and a resin film.

The 1st wiring electrode 8 is a member which plays the role for applying a voltage to the 1st detection electrode 3a and the 2nd detection electrode 4a. One end of the first wiring electrode 8 is electrically connected to the first detection electrode 3 a and the second detection electrode 4 a, and the other end is electrically connected to the first flexible substrate 10 and the second flexible substrate 20. ing. For example, the first wiring electrode 8 is made of a metal thin film so as to be hard and have high shape stability. Examples of the metal thin film include an aluminum film, an aluminum alloy film, a laminated film of a chromium film and an aluminum film, a laminated film of a chromium film and an aluminum alloy film, a silver film, a silver alloy film, or a gold alloy film. .

  In addition, although the example using two of the 1st flexible substrate 10 and the 2nd flexible substrate 20 was demonstrated above, it is not limited to this. That is, one flexible substrate may be used.

  4 is a cross-sectional view taken along the cutting line III-III shown in FIG. As shown in FIG. 4, the first flexible substrate (second substrate) 10 includes a second base 11, a second wiring electrode 12, a covering layer 13, and a reinforcing member 14. Here, the first substrate (the first base 2 and the first wiring electrode 8) and the first flexible substrate 10 are an embodiment of the wiring substrate according to the present invention.

  The second substrate 11 has insulation and flexibility. The second base 11 has a first main surface 11a and a second main surface 11b. The second base 11 is made of, for example, polyimide resin or polyester resin.

  The second wiring electrode 12 is provided on the first main surface 11 a side of the second base 11. Examples of the constituent material of the second wiring electrode 12 include metal materials such as copper, aluminum, nickel, gold, and stainless steel.

  The covering layer 13 is a member that plays a role of covering the second wiring electrode 12 so that the second wiring electrode 12 is exposed at the end 111 on the connection side of the second base 11. That is, the covering layer 13 located at the end 111 is cut out so that the second wiring electrode 12 is exposed at the end 111 on the connection side of the second base 11. The covering layer 13 is provided via a conductive member 30 and a space S1, which will be described later. The covering layer 13 is made of, for example, a polyimide resin or a polyester resin.

  Note that a plating layer 12 a is formed on the exposed second wiring electrode 12. By forming the plating layer 12a on the exposed second wiring electrode 12, the possibility that the exposed second wiring electrode 12 is oxidized can be reduced.

  Further, the first wiring electrode 8 and the exposed second wiring electrode 12 are electrically connected through the conductive member 30. Accordingly, it is possible to apply a voltage to the detection electrodes 3 a and 4 a via the second wiring electrode 12 and the first wiring electrode 8 in the first flexible substrate 10. Here, examples of the conductive member 30 include solder and an anisotropic conductive film (ACF).

  The reinforcing member 14 is a member that plays a role of reinforcing the second base 11. The reinforcing member 14 is made of, for example, a polyimide resin, a polyester resin, a glass epoxy resin, paper phenol, or a metal plate.

  The reinforcing member 14 is provided from the first region B1 corresponding to the space S1 to the second region B2 corresponding to the coating layer 13 on the second main surface 11b side of the second base body 11. Since the reinforcing member 14 is provided from the first region B1 to the second region B2, even if the first flexible substrate 10 is bent in the direction of the arrow shown in FIG. The possibility of occurrence of problems such as disconnection can be reduced.

Specifically, with the first wiring electrode 8 and the exposed second wiring electrode 12 electrically connected by the conductive member 30, the first flexible board 10 is bent in the direction of the arrow shown in FIG. When used, the bending stress concentrates on the portion A1 in FIG. For this reason, the second wiring electrode 12 located in the portion A1 in FIG. Therefore, by providing the reinforcing member 14 from the first region B1 to the second region B2 as in the present embodiment, it is possible to reduce the possibility of bending stress concentrating on the portion A1 in FIG. Thereby, it is possible to reduce the possibility that a failure such as disconnection occurs in the second wiring electrode 12 located in the portion A1 in FIG.

  In the present embodiment, since the reinforcing member 14 is not provided in the third region B3 corresponding to the conductive member 30, the connection reliability between the first wiring electrode 8 and the exposed second wiring electrode 12 by the conductive member 30 is provided. The possibility that the performance is lowered can be reduced.

  Specifically, when the wiring board is manufactured, when the first wiring electrode 8 and the exposed second wiring electrode 12 are electrically connected by the conductive member 30, a jig (not shown) is connected to the third region B3. The first wiring electrode 8 and the exposed second wiring electrode 12 were electrically connected by the conductive member 30 by pressing and heating to pressurize. Here, if the reinforcing member 14 is provided in the third region B <b> 3, thermocompression bonding is performed via the reinforcing member 14, and heat cannot be sufficiently applied to the conductive member 30. The connection reliability between the first wiring electrode 8 and the exposed second wiring electrode 12 by the member 30 may be lowered. On the other hand, in this embodiment, since the reinforcing member 14 is provided from the first region B1 to the second region B2 (that is, not provided in the third region B3), the reinforcing member 14 is interposed therebetween. It is possible to press the jig directly against the third region B3 without heating. As a result, the first wiring electrode 8 and the exposed second wiring electrode 12 can be reliably connected by the conductive member 30. As a result, in the input device X1, the possibility that the connection reliability between the first wiring electrode 8 and the exposed second wiring electrode 12 by the conductive member 30 is reduced can be reduced.

  Note that the second flexible substrate 20 may have the same configuration as that of the first flexible substrate 10.

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

When the finger F1, which is a conductor, approaches, contacts, or presses the operation surface 2a of the first base 2 corresponding to the input area E _I , the capacitance between the finger F1 and the detection electrodes 3a, 4a changes. . Here, a position detection driver (not shown) always detects a change in capacitance between the finger F1 and the detection electrodes 3a and 4a. When the position detection driver detects a change in capacitance that is equal to or greater than a predetermined value, the position detection driver detects a position where the change in capacitance is detected as an input position. In this way, the input device X1 can detect the input position. Note that the input device X1 may detect either the input position or the mutual capacitance method or the self-capacitance method. Employing the mutual capacitance method is preferable compared to the case of employing the self-capacitance method because a plurality of input positions can be detected simultaneously.

  As described above, in the input device X1 described above, the connection reliability between the first wiring electrode 8 and the second wiring electrode 12 by the conductive member 30 is reduced while reducing the possibility of the occurrence of problems such as disconnection in the second wiring electrode 12. The possibility that the performance is lowered can be reduced.

  Next, the display device Y1 including the input device X1 will be described with reference to FIG.

  As shown in FIG. 5, the display device Y1 according to the present embodiment includes an input device X1 and a liquid crystal display device Z1 disposed to face the input device X1.

  The liquid crystal display device Z1 includes a liquid crystal display panel 101, a backlight 102, and a first housing 103.

  The liquid crystal display panel 101 is a display panel using a liquid crystal composition for display. Instead of the liquid crystal display panel 101, a display panel such as a plasma display, an organic EL display, or electronic paper may be used. The backlight 102 includes a light source 102a and a light guide plate 102b. The light source 102a is a member that plays a role of emitting light toward the light guide plate 102b, and includes, for example, an LED (Light Emitting Diode). Instead of the LED, a cold cathode fluorescent lamp, a halogen lamp, a xenon lamp, or an EL (Electro-Luminescence) may be used. The light guide plate 102b is a member that plays a role of guiding light from the light source 102a substantially uniformly over the entire lower surface of the liquid crystal display panel 101.

  The first housing 103 serves to accommodate the liquid crystal display panel 101 and the backlight 102, and includes an upper housing 103a and a lower housing 103b. 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 bonded via the double-sided tape 104 so that the back surface 2b of the base 2 in the input device X1 is disposed to face the main surface of the liquid crystal display panel 101. 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 while seeing through the liquid crystal display panel 101 of the liquid crystal display device Z1, by inputting operation of the input region E _I of the input device X1, it is possible to input various information. 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 prevent the first wiring electrode 8 and the second wiring electrode 12 from being formed by the conductive member 30 while reducing the possibility that the second wiring electrode 12 is broken. The possibility that the connection reliability is lowered can be reduced.

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

  As illustrated in FIG. 6, the mobile terminal P1 according to the present embodiment is a device such as a mobile phone, a smartphone, or a PDA, and includes a display device Y1, an audio input unit 201, an audio output unit 202, and a key. An input unit 203 and a second housing 204 are provided.

  The voice input unit 201 is composed of, for example, a microphone or the like, and inputs a user's voice or the like. The audio output unit 202 includes a speaker or the like, and outputs audio from the other party. The key input unit 203 is configured by, for example, a mechanical key. The key input unit 203 may be an operation key displayed on the display screen. The second housing 204 is a member that plays a role of housing the display device Y <b> 1, the voice input unit 201, the voice output unit 202, and the key input unit 203.

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 possibility that the second wiring electrode 12 has a problem such as disconnection, while the first wiring electrode 8 and the second wiring electrode 12 formed by the conductive member 30 are reduced. The possibility that the connection reliability is lowered can be reduced.

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

  Here, the display device Y1 is not limited to the portable terminal P1 described above, but various devices such as a programmable display, an electronic notebook, a personal computer, a copying machine, a game terminal device, a television, and a digital camera used for industrial purposes. The device may be provided.
