And the photosensitive resin is apply | coated to the surface of this film | membrane, the 1st detection electrode pattern 3 and the 2nd detection electrode pattern 4 are formed by patterning a film | membrane through an exposure, image development, and an etching process.

  Next, referring to FIGS. 4 to 6 in addition to FIGS. 1 to 3, the first light shielding layer 6, the first protective layer 7, the detection wiring 8, the second protective layer 9, the vibrating body 10, and The adhesive member 11 will be described in detail.

For example, when the input device X1 is incorporated in the display device Y1 (see FIGS. 8 and 9), the first light shielding layer 6 has a role of shielding light incident on the input device X1 from the backlight 500. That is, the first light shielding layer 6 has a light shielding property. Here, “light shielding” in the present embodiment means that part or all of visible light is shielded by reflection or absorption. The first light shielding layer 6 preferably has an OD value (Optical Density) of 3 μm or more with a thickness of 1 μm.

  The first light shielding layer 6 is provided on the second main surface 1B of the base 1 corresponding to the non-input area E2. Specifically, the first light shielding layer 6 is provided in a frame shape so as to surround the input region E1 in plan view. In addition, the 1st light shielding layer 6 may be provided on the 2nd protective layer 9 mentioned later. Examples of the constituent material of the first light shielding layer 6 include a resin material containing a coloring material. Examples of the resin material include acrylic resins, epoxy resins, and silicone resins. Examples of the coloring material include carbon, titanium, and chromium. In addition, the 1st light shielding layer 6 may be colored not only black but colors other than black. Examples of the method for forming the first light shielding layer 6 include a screen printing method, a sputtering method, a CVD method, and a vapor deposition method.

  Here, a first cutout portion 6 a is provided in a part of the first light shielding layer 6. The first notch 6a is provided in the vicinity of the short side of the base 1 in plan view. Specifically, the two first cutouts 6a are provided and are opposed to each other across the input area E1 in plan view. In addition, about the number of the 1st notch parts 6a, planar view shape, or an arrangement position, it can change suitably. In the present embodiment, the first cutout portion 6a is provided by opening a part of the first light shielding layer 6 and indicates the entire opened area, but is not limited thereto. The first notch 6a may be provided so that a part of the first light shielding layer 6 is recessed in plan view. In such a case, the 1st notch part 6a points out the said recessed whole area | region.

  The first protective layer 7 has a role of protecting the first light shielding layer 6. Here, as a role of protecting the first light shielding layer 6, for example, a role of protecting the first light shielding layer 6 from corrosion due to moisture absorption, or a possibility that the material of the first light shielding layer 6 is altered. The role to reduce is mentioned. The first protective layer 7 is provided on the second main surface 1B of the base 1. Specifically, the first protective layer 7 covers the first light shielding layer 6. Moreover, the 1st protective layer 7 is notched corresponding to the 1st notch part 6a. Examples of the constituent material of the first protective layer 7 include an acrylic resin, a silicone resin, a rubber resin, a urethane resin, or an inorganic compound containing silicon. Examples of the method for forming the first protective layer 7 include a transfer printing method, a spin coating method, and a slit coating method.

  The detection wiring 8 has a role of detecting a change in capacitance generated between the first detection electrode pattern 3 and the second detection electrode pattern 4 and the finger F1. The detection wiring 8 is provided on the first protective layer 7 corresponding to the non-input area E2. Specifically, the detection wiring 8 is located on the side farther from the second main surface 1B of the base body 1 than the first light shielding layer 6 and overlaps the first light shielding layer 6 in plan view. Yes. For this reason, when the input device X1 is incorporated in the display device Y1, it is possible to reduce the possibility that the detection wiring 8 is visually recognized by light incident on the input device X1 from the backlight 500. The detection wiring 8 may be located closer to the second main surface 1B of the base body 1 than the first light shielding layer 6.

  One end of the detection wiring 8 is electrically connected to the first detection electrode pattern 3 and the second detection electrode pattern 4. The other end of the detection wiring 8 is located in the external conduction region G1. The other end of the detection wiring 8 is electrically connected to a position detection driver (not shown) through a flexible printed wiring board (not shown) in the external conduction region G1. In the present embodiment, the external conduction region G1 is located between the input region E1 and the first notch 6a in plan view, but is not limited thereto. The first notch 6a may be located between the input area E1 and the external conduction area G1 in plan view. In such a case, it is preferable that the detection wiring 8 is routed around the first notch 6a so as not to overlap the first notch 6a in plan view.

  The detection wiring 8 is made of a metal thin film so as to be hard and have high shape stability. Examples of the constituent material 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. Can be mentioned. Examples of the method for forming the metal thin film include a sputtering method, a CVD method, and a vapor deposition method.

The second protective layer 9 is provided on the second main surface 1B of the base 1 corresponding to the non-input area E2. Specifically, the second protective layer 9 is located on the first protective layer 7 and covers the detection wiring 8. Note that the second protective layer 9 is not provided in the external conduction region G1. As a constituent material and a forming method of the second protective layer 9, the same materials as those of the first protective layer 7 are exemplified.

The vibrating body 10 has a role of vibrating the base 1 when a predetermined input operation by the user is detected. In the present embodiment, the vibrating body 10 is a piezoelectric element in which dielectric layers 10a and electrode layers 10b are alternately stacked. That is, the base body 1 is curved and vibrated in the thickness direction of the base body 1 (Z direction in FIGS. 2 to 4 and 6) by the vibrating body 10 that repeatedly expands and contracts in the X direction according to the applied voltage. Become. Although details will be described later, the vibrating body 10 also has a role of detecting a pressing load on the base body 1. The vibrating body 10 may be any object that vibrates, and an electromagnetic vibrating body, a motor, or the like may be used instead of the piezoelectric element. Further, as the piezoelectric element, for example, either a unimorph type or a bimorph type may be adopted. Note that the vibrating body 10 does not have to transmit vibration directly to the base 1. That is, for example, as the vibrating body 10, a piezoelectric element may be housed in a metal casing, and the base body 1 may be vibrated via the metal casing. In this case, the vibrating body 10 is constituted by a piezoelectric element and a metal housing. As described above, the configuration of the vibrating body 10 can be variously modified without departing from the spirit of the present invention.

  The vibrating body 10 is provided on the second main surface 1B of the base 1 corresponding to the non-input area E2. Specifically, the vibrating body 10 is provided so as to overlap the first notch 6a in plan view. Here, the second main surface 1B of the base 1 includes an exposed surface 1D exposed from the first light shielding layer 6, and the vibrating body 10 has a facing surface 10A facing the exposed surface 1D. For this reason, the vibrating body 10 is provided on the exposed surface 1D. Therefore, in the input device X1, the possibility that the first light shielding layer 6 is peeled off from the second main surface 1B of the base body 1 can be reduced.

  Specifically, in the conventional input device, the vibrating body is provided so as to overlap the first light shielding layer in plan view in order to reduce the possibility that the area of the non-input region becomes relatively large. However, the first light shielding layer contains a coloring material for the purpose of providing light shielding properties, for example. Here, the coloring material has a relatively low possibility of contributing to adhesion. For this reason, the first light-shielding layer may have relatively low adhesion to the second main surface of the substrate. Therefore, there is a possibility that the first light shielding layer may be peeled off from the second main surface of the base body when the vibrating body vibrates repeatedly according to the user's input operation. In addition, in order to solve said problem, when the 1st light shielding layer is comprised with an adhesive film, the vibration in a vibrating body may be inhibited by the said 1st light shielding layer, and the base | substrate 1 may not fully vibrate.

  Therefore, in the input device X1, the first cutout portion 6a is provided in a part of the first light shielding layer 6. Further, the vibrating body 10 is provided on the exposed surface 1D exposed from the first light shielding layer 6 in the first cutout portion 6a. For this reason, it is possible to reduce the possibility that the vibration transmitted from the vibrating body 10 to the base body 1 is suppressed by the first light shielding layer 6 without relatively increasing the area of the non-input region E2. Therefore, the possibility that the first light shielding layer 6 is peeled off from the second main surface 1B of the base body 1 due to the influence of the vibration can be reduced.

  Note that, as in the present embodiment, the vibrating body 10 is preferably bonded to the exposed surface 1 </ b> D via the adhesive member 11. When the vibrating body 10 is bonded to the exposed surface 1D via the adhesive member 11, the possibility that the vibrating body 10 is peeled off from the exposed surface 1D can be reduced. Examples of the constituent material of the adhesive member 11 include a silicone-based adhesive material or an epoxy-based adhesive material. The adhesive member 11 may be an adhesive tape material such as a double-sided tape. Note that the vibrating body 10 may be held on the exposed surface 1D by, for example, a mechanical stopper.

  Moreover, it is preferable that the exposed surface 1 </ b> D is also exposed from the first protective layer 7 as in the present embodiment. Specifically, it is preferable that the vibrating body 10 is directly bonded to the exposed surface 1 </ b> D via the adhesive member 11. When the vibrating body 10 is directly bonded to the exposed surface 1D, the possibility that the vibration of the vibrating body 10 is transmitted to the base body 1 can be increased.

  Further, as in the present embodiment, it is preferable that the entire vibrating body 10 overlaps the exposed surface 1D in plan view. If the entire vibrating body 10 overlaps the exposed surface 1D in plan view, the possibility that the vibration of the vibrating body 10 is transmitted to the first light shielding layer 6 can be further reduced. Note that the entire vibrating body 10 does not have to overlap the exposed surface 1D in plan view, and at least a part of the vibrating body 10 may overlap with the exposed surface 1D in plan view.

In the present embodiment, a part of the adhesive member 11 overlaps the first light shielding layer 6 in plan view, but the present invention is not limited to this. The whole adhesive member 11 may overlap with the exposed surface 1D. If the entire adhesive member 11 overlaps the exposed surface 1D, the possibility that the vibration of the vibrating body 10 is transmitted to the first light shielding layer 6 via the adhesive member 11 can be reduced. For this reason, it is possible to further reduce the possibility that the first light shielding layer 6 is peeled off from the second main surface 1B of the base body 1 due to the vibration of the vibrating body 10.

  In the present embodiment, the first detection electrode pattern 3, the second detection electrode pattern 4, the insulator 5, and the detection wiring 8 are directly provided on the substrate 1, but this is not restrictive. Each of the above members may be provided directly on a support plate (not shown) disposed on the second main surface 1B of the base 1, for example. According to such a configuration, the number of members provided directly on the substrate 1 can be reduced. For this reason, the possibility that the vibration of the vibrating body 10 is transmitted to the base body 1 can be increased.

  Further, the input device X1 may include a decoration layer (not shown). Specifically, the decorative layer is provided on the first main surface 1A of the base 1 corresponding to the non-input area E2, and may overlap the first notch 6a in plan view. If the decorative layer overlaps the first cutout portion 6a in plan view, the possibility that the vibrating body 10 will be visually recognized by the user can be reduced.

  In the present embodiment, the vibrating body 10 has a rectangular shape in plan view, but is not limited thereto. In the present embodiment, two vibrating bodies 10 are provided so as to correspond to the two first cutout portions 6a, and are opposed to each other across the input region E1 in plan view. Not limited to this. That is, the number, the shape in plan view, or the arrangement position of the vibrating bodies 10 can be changed as appropriate without departing from the spirit of the present invention.

  Next, an operation example of the input device X1 will be described with reference to FIG.

  In the following, an operation example of the input device X1 in the case of transmitting a pressing feeling to the user in tactile transmission will be described. Of course, the present invention can also be applied to transmitting various tactile sensations.

  As shown in FIG. 7, the vibrating body 10 detects the pressing load when the user presses the base 1 from the first main surface 1A to the second main surface 1B (Op1). Here, the load detection function of the vibrating body 10 will be described. That is, when the user presses the base 1 from the first main surface 2A to the second main surface 1B, the base 1 is bent from the first main surface 1A to the second main surface 1B. When the base body 1 is bent from the first main surface 1A to the second main surface 1B, the vibrating body 10 is also bent in the same direction. That is, the bending amount of the vibrating body 10 changes according to the pressing load on the base body 1. As a result, the pressing load on the base 1 can be detected by the vibrating body 10.

  Then, when the input operation by the user is a pressing operation on the input object, the tactile transmission driver (not shown) determines whether or not the pressing load detected in Op1 is equal to or greater than the threshold (Op2).

If the tactile transmission driver determines that the pressing load detected at Op1 is equal to or greater than the threshold value (YES at Op2), the tactile transmission driver causes the vibrating body 10 to expand and contract in the X direction (Op3). Then, the base body 1 is curved and vibrated in the Z direction by the vibrating body 10 expanded and contracted in Op3 (Op4). Thereby, a pressing feeling is transmitted to the user who pressed the base 1 from the first main surface 1A to the second main surface 1B. On the other hand, if the tactile sensation transmission driver determines that the pressing load detected at Op1 is less than the threshold (NO at Op2), the process of FIG. 7 ends. In the present embodiment, the example in which vibration is transmitted to the base 1 by the vibrating body 10 expanding and contracting has been described, but the present invention is not limited thereto. The vibrating body 10 may transmit vibration to the base 1 by, for example, longitudinal vibration or lateral vibration.

  As described above, the input device X1 can reduce the possibility that the first light shielding layer 6 is peeled off from the second main surface 1B of the base 1.

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

  As shown in FIGS. 8 and 9, the display device Y1 according to the present embodiment includes an input device X1, a first housing 100, an elastic member 200, a support member 300, a display panel 400, a backlight 500, and a circuit board 600. It has. In FIG. 8, the display panel 400, the backlight 500, and the circuit board 600 are not shown, and the region where the support member 300 is located is indicated by a dotted line.

  The first casing 100 has a role of housing the display panel 400, the backlight 500, and the circuit board 600, and also has a role of supporting the input device X1. The first housing 100 has a base portion 101 and a frame portion 102. The base 101 is disposed to face the second main surface 1B of the input device X1. The frame portion 102 is provided on the base portion 101 and surrounds the end surface 1C of the base 1 in the input device X1. Examples of the constituent material of the first housing 100 include a resin such as polycarbonate, or a metal such as stainless steel and aluminum.

The elastic member 200 has a role of assisting the frame portion 102 to support the input device X1. The elastic member 200 is sandwiched between the end surface 1C of the base body 1 and the frame portion 102 in the input device X1. That is, the elastic member 200 supports the base 1 in the X direction or the Y direction. For this reason, the possibility that the vibration of the input device X1 is suppressed in the Z direction can be reduced. Further, the elastic member 200 is positioned so as to surround the end surface 1 </ b> C of the base 1. For this reason, the dustproof property or waterproofness of the display apparatus Y1 can be improved. As a constituent material of the elastic member 200, for example, a rubber-based or foamed resin-based elastic material is used. Examples of rubber-based elastic materials include polybutadiene, nitrile, chloroprene, cis-polyisoprene, and silicon. Examples of the foamed resin-based elastic material include polyurethane, polystyrene, polyolefin, and polypropylene.

  The support member 300 has a role of supporting the input device X1 in the Z direction. The support member 300 is provided on the base 101. The support member 300 supports the input device X1 on the second main surface 1B side of the base 1. Further, the support member 300 is disposed corresponding to the four corners of the base 1 in the input device X1 and the central part of the two long sides of the base 1 in plan view. For this reason, tactile sense can be easily transmitted to the user. For example, the support member 300 has a certain degree of elasticity so as not to suppress the vibration of the input device X1 and can be formed of a material having a larger elastic modulus than the elastic member 200.

The display panel 400 has a role of displaying an image. The display panel 400 is spaced apart from the input device X1 through a space, and is disposed to face the second main surface 1B of the base 1. Note that the display panel 400 may not be separated from the input device X1 via a space, and may be bonded to the input device X1 via an optical adhesive member, for example. The display panel 400 includes an upper substrate 401, a lower substrate 402, a liquid crystal layer 403, and a sealing member 404. The upper substrate 401 is located closer to the input device X1 than the lower substrate 402. The lower substrate 402 is positioned to face the upper substrate 401. The liquid crystal layer 403 is located between the upper substrate 401 and the lower substrate 402. Specifically, the liquid crystal layer 403 is supported in a region between the upper substrate 401 and the lower substrate 402 by the upper substrate 401, the lower substrate 402, and the sealing member 404.

  As described above, the display device Y1 can input various kinds of information by performing an input operation on the input area E1 of the input device X1 while seeing through the display panel 400 through the input device X1.

  As described above, since the display device Y1 includes the input device X1, the possibility that the first light shielding layer 6 is peeled off from the second main surface 1B of the base 1 can be reduced.

  Next, the portable terminal Z1 provided with the display device Y1 will be described with reference to FIG.

  As shown in FIG. 10, the mobile terminal Z1 according to the present embodiment is a smartphone terminal. The mobile terminal Z1 is not limited to a smartphone terminal, and may be an electronic device such as a mobile phone, a tablet terminal, or a PDA (Personal Digital Assistant).

  The mobile terminal Z1 includes a display device Y1, an audio input unit 701, an audio output unit 702, a key input unit 703, and a second housing 704.

However, illustration and description of these details are omitted.

  As described above, since the mobile terminal Z1 includes the display device Y1, the possibility that the first light shielding layer 6 is peeled off from the second main surface 1B of the base 1 can be reduced.

  The above-described embodiment shows a specific example of the embodiment of the present invention, and various modifications are possible. Hereinafter, some main modifications will be described. In each drawing referred to in each modification shown below, members having the same functions as those shown in FIGS. 1 to 6 are denoted by the same reference numerals, and detailed description thereof is omitted.

[Modification 1]
In the first modification, the input device X2 will be described in detail with reference to FIG. 11 and FIG. Here, FIG. 11 is a diagram showing the same portion of the input device X2 as that of the input device X1 shown in FIG. 12 is a cross-sectional view taken along line VI-VI shown in FIG.

  As shown in FIGS. 11 and 12, the input device X2 includes an adhesive member 21 instead of the adhesive member 11 included in the input device X1.

  The bonding member 21 has a role of bonding the facing surface 10 </ b> A of the vibrating body 10 and the exposed surface 1 </ b> D of the base 1. The adhesive member 21 is located between the facing surface 10 </ b> A of the vibrating body 10 and the exposed surface 1 </ b> D of the base 1. Further, the adhesive member 21 is positioned so as to overlap the first notch 6a in plan view. Here, the adhesive member 21 has a light shielding property. For this reason, possibility that the vibrating body 10 will be visually recognized by a user can be reduced.

  Specifically, when the vibrating body 10 is provided on the exposed surface 1D, at least a part of the vibrating body 10 overlaps the first notch 6a in plan view. For this reason, the vibrating body 10 may be visually recognized by the user. Therefore, in Modification 2, the adhesive member 21 has a light shielding property. When the adhesive member 21 has a light shielding property, it is possible to shield a region where the vibrating body 10 and the first cutout portion 6a overlap in plan view. For this reason, possibility that the vibrating body 10 will be visually recognized by a user can be reduced.

  Note that, as in the first modification, the adhesive member 21 preferably overlaps the entire first notch 6a in plan view. When the adhesive member 21 overlaps with the entire first notch 6a in plan view, the entire region where the first notch 6a is located can be shielded from light.

As a constituent material of the adhesive member 21, a resin material in the input device X1 that includes a coloring material can be used. The adhesive member 21 preferably has an OD value (Optical Density) of 1 μm or more in a range of 2 or more. The resin material constituting the adhesive member 21 may be either photosensitive or non-photosensitive, and specifically, an epoxy resin, a polyimide resin, or the like can be used. In particular, it is preferable to use an epoxy resin from the viewpoint of excellent adhesive strength. In addition, when using photosensitive resin, the adhesive member 21 can be hardened through the 1st notch part 6a by irradiating light from the 1st main surface 1A side of the base | substrate 1 which has translucency. it can. Further, it is desirable that the coloring material constituting the adhesive member 21 has an insulating property from the viewpoint of preventing a short circuit between electrodes formed on the outer surface of the vibrating body 10. As the coloring material, for example, a black organic pigment, a mixed color organic pigment, or an inorganic pigment is preferably used. Examples of the black organic pigment include carbon black, perylene black, and aniline black. Examples of mixed color organic pigments include those obtained by mixing a plurality of pigments selected from red, blue, green, violet, yellow, magenta, cyan, and the like, and blackening them. Examples of inorganic pigments include fine metal particles such as graphite, titanium, copper, iron, manganese, cobalt, chromium, nickel, zinc, calcium, and silver, metal oxides, and composite oxides. In addition, it is preferable to contain 5-30 weight% of the above-mentioned coloring material. The thickness of the adhesive member 21 is preferably in the range of 5 to 30 μm from the viewpoint of improving the adhesive strength. According to such a configuration, it is possible to reduce the possibility that the adhesive member 21 is peeled off from the exposed surface 1D while reducing the possibility that the vibrating body 10 is visually recognized by the user. In addition, the vibrating body 10 can also be adhere | attached on the exposed surface 1D through the adhesive member 21 as the adhesive adhesive tape material (double-sided tape) colored in the desired color with the method similar to the above.

[Modification 2]
In the second modification, the input device X3 will be described in detail with reference to FIGS. 13 and 14. Here, FIG. 13 is a diagram showing the same part of the input device X3 as the input device X1 shown in FIG. FIG. 14 is a cross-sectional view taken along line VII-VII shown in FIG.

  As shown in FIGS. 13 and 14, the input device X3 includes a first light shielding layer 31 and an adhesive member 32 instead of the first light shielding layer 6 and the adhesive member 11 provided in the input device X1.

  The first light shielding layer 31 is provided on the second main surface 1B of the base 1 corresponding to the non-input area E2. Further, a first cutout portion 31 a is provided in a part of the first light shielding layer 31. The first notch 31a is provided corresponding to the short side of the base 1 in plan view. Specifically, two first cutout portions 31a are provided, and are opposed to each other across the input region E1 in plan view.

  The bonding member 32 has a role of bonding the facing surface 10 </ b> A of the vibrating body 10 and the exposed surface 1 </ b> D of the base 1. The adhesive member 32 is located between the facing surface 10 </ b> A of the vibrating body 10 and the exposed surface 1 </ b> D of the base 1. Further, the adhesive member 32 is positioned so as to overlap the first cutout portion 31a in plan view. Specifically, the adhesive member 32 overlaps with the entire first cutout portion 31 a in plan view, and partially overlaps with the first light shielding layer 31. Further, the adhesive member 32 has a light shielding property. For this reason, in the area | region where the 1st notch part 31a is located planarly, possibility that the vibrating body 10 will be visually recognized by a user can be reduced.

Here, the 1st light shielding layer 31 has the gradation pattern 31b located in the vicinity of the outer edge of the 1st notch part 31a in planar view. Here, the gradation pattern 31b is a part having a function of changing the hue step by step in a part that changes from the first light shielding layer 31 to the adhesive member 32 in plan view. In the second modification, the gradation pattern 31b refers to a portion of the first light shielding layer 31 that overlaps the adhesive member 32 in plan view. In the second modification, the gradation pattern 31b has a plurality of holes 31c. The plurality of holes 31c are arranged in a line along the outer edge of the first cutout 31a in plan view. The plurality of holes 31c do not have to be arranged in a line in a plan view and may be arranged randomly in a plan view. Thus, since the input device X3 has the plurality of holes 31c, the adhesive member 32 is visually recognized from the plurality of holes 31c in plan view. That is, in the plan view, in the region where the gradation pattern 31 b is located, the color of the first light shielding layer 31 and the color of the adhesive member 32 are mixed and visually recognized. For this reason, in the site | part which changes from the 1st light shielding layer 31 to the adhesive member 32 in planar view, a color can be changed in steps. Therefore, the possibility that the outer edge of the first notch 31a is visually recognized by the user in a plan view can be reduced.

  As in Modification 2, it is preferable that a part of the adhesive member 32 is positioned in the plurality of holes 31c. When a part of the adhesive member 32 is located in the plurality of holes 31c, the possibility that the adhesive member 32 is peeled off from the exposed surface 1D due to the anchor effect can be reduced.

  Further, as in Modification 2, the gradation pattern 31b is preferably positioned so as to surround the first notch 6a in plan view. When the gradation pattern 31b surrounds the first cutout portion 31a in plan view, the possibility that the outer edge of the first cutout portion 31a is visually recognized by the user can be further reduced.

  In the above description, an example in which the plurality of holes 31c are provided in a line as the gradation pattern 31b has been described, but the present invention is not limited thereto. As shown in FIGS. 15 and 16, the gradation pattern 31b may have a first hole 31c1 and a second hole 31c2 as a plurality of holes 31c. Specifically, the first holes 31c1 are positioned in a line along the outer edge of the first notch 31a in plan view. The second holes 31c2 are positioned in a line along the outer edge of the first notch 31a in plan view. Here, the second hole 31c2 is located farther from the outer edge of the first notch 31a than the first hole 31c1 in plan view. Further, the area of the second hole 31c2 in plan view is smaller than the area of the first hole 31c1 in plan view. For this reason, in the site | part which changes from the 1st light shielding layer 31 to the adhesive member 32 in planar view, a color can be changed in steps. Therefore, the possibility that the outer edge of the first notch 31a is visually recognized by the user in plan view can be further reduced.

  Further, as shown in FIGS. 17 and 18, the gradation pattern 31b may have a plurality of light shielding dots 31d instead of the plurality of holes 31c. Specifically, the plurality of light shielding dots 31d are arranged in a line along the outer edge of the first notch 31a in plan view. The plurality of light-shielding dots 31d do not have to be arranged in a line in a plan view, and may be randomly arranged in a plan view. As described above, even when the gradation pattern 31b includes the plurality of light-shielding dots 31d, the outer edge of the first cutout portion 31a may be visually recognized by the user in plan view, similarly to the configuration including the plurality of holes 31c. Can be reduced.

  Further, as shown in FIGS. 19 and 20, the gradation pattern 31b may be configured not to have a plurality of holes 31c and a plurality of light shielding dots 31d. Specifically, the gradation pattern 31b may be configured such that the thickness decreases as the first cutout portion 31a is approached. According to such a configuration, the color can be changed in a stepwise manner at a portion where the first light shielding layer 31 changes to the adhesive member 32 in plan view. Therefore, the possibility that the outer edge of the first notch 31a is visually recognized by the user in plan view can be further reduced.

[Modification 3]
In Modification 3, the input device X4 will be described in detail with reference to FIGS. 21 and 22. Here, FIG. 21 is a diagram showing the same part of the input device X4 as the input device X1 shown in FIG. FIG. 22 is a cross-sectional view taken along line XI-XI shown in FIG.

As shown in FIGS. 21 and 22, in the input device X4, the vibrating body 1 included in the input device X1.
Instead of 0, a vibrating body 41 is provided. The input device X4 further includes a second light shielding layer 42.

  The vibrating body 41 is a stacked piezoelectric element in which dielectric layers 41a and electrode layers 41b are alternately stacked. The vibrating body 41 is provided so as to overlap the first cutout portion 6a in plan view. For this reason, that is, the vibrating body 41 is provided on the exposed surface 1D. Moreover, the vibrating body 41 has a facing surface 41A that faces the exposed surface 1D. The vibrating body 41 is positioned so as to overlap with the entire first notch 6a in plan view. Specifically, the vibrating body 41 is provided slightly larger than the first cutout portion 6a in plan view.

  The second light shielding layer 42 is provided on the facing surface 41 </ b> A of the vibrating body 41. For this reason, the area | region where the vibrating body 41 and the 1st notch part 6a overlap can be shielded from light in planar view. Therefore, the possibility that the vibration body 41 is visually recognized by the user can be reduced. As a constituent material and a forming method of the second light shielding layer 42, the same materials as those of the first light shielding layer 6 or the adhesive member 21 may be used. Note that it is preferable that the facing surface 41A of the vibrating body 41 has a rough surface as compared to a surface other than the facing surface. Specifically, the facing surface 41A of the vibrating body 41 is preferably formed to be rough, for example, by performing a blasting process or the like. According to such a configuration, it is possible to reduce a possibility that the second light shielding layer 42 provided on the facing surface 41A of the vibrating body 41 is peeled off from the facing surface 41A.

  Note that, as in Modification 3, the second light shielding layer 42 is preferably provided over the entire facing surface 41 </ b> A of the vibrating body 41. Specifically, it is preferable that the second light shielding layer 42 overlaps the entire vibrating body 42 in plan view. When the second light shielding layer 42 is provided over the entire surface 41A of the vibrating body 41, the possibility that the vibrating body 41 is visually recognized by the user can be further reduced.

  In addition, as in Modification 3, it is preferable that the second light shielding layer 42 overlaps the entire first cutout 6a in plan view. If the second light shielding layer 42 overlaps with the entire first cutout 6a in plan view, when the input device X4 is incorporated in the display device Y1 instead of the input device X1, the inside of the display device Y1 is the user. The possibility of being visually recognized can be reduced.

  Further, the first light shielding layer 6 and the second light shielding layer 42 may have substantially the same color. If the first light shielding layer 6 and the second light shielding layer 42 have substantially the same color, it is possible to reduce the possibility that the outer edge of the first notch 6a is visually recognized by the user in a plan view. For this reason, the designability improves. Note that “substantially the same color” means, for example, that the hue symbol of hue, lightness, and saturation is the same in the Munsell color system, and the difference between the numerical values of hue, lightness, and saturation is within one. Can be defined as

  Further, the second light shielding layer 42 may have a gradation pattern in the vicinity of the outer edge of the first notch 6a in plan view. When the 2nd light shielding layer 42 has a gradation pattern, possibility that the user may visually recognize the outer edge of the 1st notch part 6a planarly can be reduced. For this reason, the designability improves. In addition, as the gradation pattern in the modification 3, the thing similar to the gradation pattern 31b shown in the modification 2 is employable.

In the above description, the example in which the second light shielding layer 42 is directly provided on the facing surface 41 </ b> A of the vibrating body 41 has been described, but the present invention is not limited thereto. 23 and 24, the input device X4 may further include a shim plate 43 between the facing surface 41A of the vibrating body 42 and the second light shielding layer 42. In this case, the vibrating body 42 is bonded to the shim plate 43 via an adhesive material (not shown). Here, the shim plate 43 is a substrate for mounting the vibrating body 42. Examples of the constituent material of the shim plate 43 include a metal material and a resin material. In FIG. 23 and FIG. 24, the second light shielding layer 42 is positioned on the shim plate 43, but the present invention is not limited to this. As the shim plate 43, a resin plate or the like produced by injection molding or the like using a resin material colored in a desired color can be used. By changing the hardness of the material used as the shim plate 43, the way in which vibration is transmitted from the vibrating body 41 to the base body 1 is different, so that more versatile tactile sensations can be transmitted to the user.

[Modification 4]

  As shown in FIGS. 25 to 28, the input device X <b> 5 further includes a third protective layer 51.

  The third protective layer 51 is provided on the second main surface 1B of the base 1 corresponding to the input area E1 and the non-input area E2. The third protective layer 51 is located above the first detection electrode pattern 3 and the second detection electrode pattern 4. For this reason, the first detection electrode pattern 3 and the second detection electrode pattern 4 can be protected from mechanical shock or electrostatic noise. The third protective layer 51 is located on the detection wiring 8. For this reason, the detection wiring 8 can be protected from mechanical shock or electrostatic noise.

  Here, a part of the third protective layer 51 is provided with a second cutout part 51a that overlaps the first cutout part 6a in plan view. Therefore, the exposed surface 1D of the base 1 is formed with the second cutout part. The portion 51a is exposed from the third protective layer 51. Therefore, in the input device X5, even if the third protective layer 51 is provided, the vibrating body 10 can be provided on the exposed surface 1D.

  Examples of the third protective layer 51 include an adhesive film including an acrylic adhesive, a silicone adhesive, a rubber adhesive, or a urethane adhesive.

  As in Modification 1, the second cutout portion 51a preferably overlaps with the entire first cutout portion 6a in plan view. When the second cutout portion 51a overlaps with the entire first cutout portion 6a in plan view, the area of the exposed surface 1D bonded to the facing surface 10A of the vibrating body 10 via the adhesive member 11 is relatively large. can do.

  In the first modification, the second cutout portion 51a has substantially the same shape as the first cutout portion 6a in plan view, but the present invention is not limited to this. For example, the second cutout portion 51a may be provided slightly larger than the first cutout portion 6a in plan view.

[Modification 5]
In Modification 5, the input device X6 will be described in detail with reference to FIGS. Here, FIG. 29 is a plan view showing a schematic configuration of the input device X6. FIG. 30 is an enlarged view of a region A3 surrounded by a one-dot chain line shown in FIG. 31 is a cross-sectional view taken along line XV-XV shown in FIG. FIG. 32 is an enlarged view of a region B1 surrounded by a one-dot chain line shown in FIG.

  As shown in FIGS. 29 to 32, the input device X6 includes a first light shielding layer 61 and an adhesive member 62 instead of the first light shielding layer 6 and the adhesive member 11 included in the input device X1.

  The first light shielding layer 61 is provided on the second main surface 1B of the base 1 corresponding to the non-input area E2. In addition, a first cutout portion 61 a is provided in a part of the first light shielding layer 61. The first notch 61a is provided corresponding to the short side of the base 1 in plan view. Specifically, the two first cutouts 61a are provided and are opposed to each other across the input region E1 in plan view. The first notch 61a is provided so that a part of the first light shielding layer 61 is recessed in plan view.

  The bonding member 62 has a role of bonding the facing surface 10 </ b> A of the vibrating body 10 and the exposed surface 1 </ b> D of the base 1. The adhesive member 62 is located between the facing surface 10 </ b> A of the vibrating body 10 and the exposed surface 1 </ b> D of the base 1. Further, the adhesive member 62 is positioned so as to overlap with the entire first notch 61a in plan view. Here, a part of the adhesive member 62 is located on a corner portion C1 formed by the second main surface 1B and the end surface 1C of the base 1. For this reason, even if a mechanical impact or heat stress is concentrated on the end surface 1C of the base body 1, the possibility of cracks occurring in the base body 1 can be reduced.

  In Modification 5, as shown in FIG. 32, the corner portion C1 is located between the second main surface 1B and the end surface 1C and the surface has an R shape. When the surface of the corner portion C1 is R-shaped, the possibility of stress concentration at the corner portion C1 can be reduced, and the possibility of cracks occurring in the substrate 1 can be reduced. The corner portion C1 may have a right-angle surface or a C-plane.

  Moreover, in the modification 5, although the adhesive member 62 has coat | covered all the corner | angular parts C1, it is not restricted to this. For example, the adhesive member 62 may be provided on at least a part of the corner C1.
