The liquid crystal panel 2, the backlight 3, the vibrating body 5, and the wiring substrate 6 are sealed by the touch panel 4, the upper casing 71, and the lower casing 72. Thereby, the liquid crystal panel 2, the backlight 3, the vibrating body 5, and the wiring board 6 can reduce the possibility that dust or water adheres from the outside.

  In the above description, an example in which the upper casing 71 and the lower casing 72 are separately configured as the first casing 7 has been described. However, the first casing 7 is not limited thereto. For example, the upper housing 71 and the lower housing 72 may be integrally configured.

  Moreover, although the 1st housing | casing demonstrated the example which accommodated the wiring board 6 with the liquid crystal panel 2, the backlight 3, and the vibrating body 5 above, it is not restricted to this. The first housing 7 may adopt a configuration in which the wiring substrate 6 is provided outside the first housing 7 without accommodating the wiring substrate 6.

Thereby, the first light source 31 of the liquid crystal panel 2 and the backlight 3 is electrically connected to the control circuit 61 via the second flexible substrate 12 and the second connector 63.

  In addition, as shown in FIG. 2, it is preferable that the upper housing | casing 71 and the 1st flexible substrate 11 have a clearance gap. This is because if the upper housing 71 and the first flexible substrate 11 are in contact with each other, the first flexible substrate 11 may be damaged by the upper housing 71. For the same reason, it is preferable that the upper housing 71 and the second flexible substrate 12 have a gap.

  In addition, although the example which implement | achieved said connection state using the two flexible substrates 11 and 12 was demonstrated above, it is not restricted to this. The above connection state may be realized using one flexible substrate, or the above connection state may be realized using three or more flexible substrates.

As shown in FIG. 2, the touch panel 4 is provided with a first light shielding film 41 and a second light shielding film 42 at a portion facing a part of the first flexible substrate 11. That is, since the touch panel 4 is provided with not only the first light shielding film 41 but also the second light shielding film 42 at a part facing the part of the first flexible substrate 11, the first flexible substrate 11 is visually recognized by the user. It is possible to reduce the possibility of being done. This will be specifically described below.

  As described above, the touch panel 4 is configured to project outward from the liquid crystal panel 2 and is disposed to face the liquid crystal panel 2 via the first space S1. For this reason, the light from the backlight 3 irradiates substantially the entire surface of the touch panel 4 through the liquid crystal panel 2. For this reason, the first flexible substrate 11 located in the first space S <b> 1 may be visually recognized by the user via the touch panel 4 due to light from the backlight 3 via the liquid crystal panel 2. In FIG. 2, the first portion of the first flexible substrate 11 located in the first space S <b> 1 is denoted by reference numeral “11 a”.

  On the other hand, in the present embodiment, the touch panel 4 is provided with the first light shielding film 41 and the second light shielding film 42 at a portion facing the first portion 11a in the first flexible substrate 11 located in the first space S1. It has been. That is, the touch panel 4 is provided with not only the first light-shielding film 41 but also the second light-shielding film 42 at a part of the first flexible substrate 11 facing the first part 11a. For this reason, it is possible to reduce the possibility that the user can visually recognize the first portion 11 a of the first flexible substrate 11 through the touch panel 4 due to the light from the backlight 3 through the liquid crystal panel 2.

In addition, when the display device X1 with an input function is provided in a mobile terminal such as a smartphone, for example, the outer region _EO of the display device X1 with an input function is displayed by illumination, for example. In this case, as shown in FIG. 3, the second light source 9 is provided on the upper surface of the lower casing 72 corresponding to the second space S2. That is, when the second light source 9 emits light, the outer area _EO of the touch panel 4 can be displayed by illumination through the second space S2. In addition, the 2nd light source 9 is comprised from LED, for example.

In the display device with an input function X1 shown in FIG. 3, the light from the second light source 9 irradiates the outer area E _O of the touch panel 4 through the second space S2. For this reason, the first flexible substrate 11 located in the second space S2 may be visually recognized by the user via the touch panel 4 due to light from the second light source 9 via the second space S2. . 2 and 3, the second portion of the first flexible substrate 11 located in the second space S <b> 2 is represented by reference numeral “11 b”.

  On the other hand, in the present embodiment, the touch panel 4 is provided with the first light shielding film 41 and the second light shielding film 42 at a portion facing the second portion 11b in the first flexible substrate 11 located in the second space S1. It has been. That is, in the touch panel 4, not only the first light shielding film 41 but also the second light shielding film 42 is provided in a portion facing the second portion 11 b in the first flexible substrate 11. For this reason, the possibility that the user may visually recognize the second portion 11b of the first flexible substrate 11 via the touch panel 4 due to the light from the second light source 9 via the second space S2. it can.

  Note that light leaking from the liquid crystal panel 2 is reflected on the upper surface of the lower housing 72, and the reflected light may irradiate the touch panel 4 via the second space S2. Therefore, also in the display device X1 with an input function shown in FIG. 2, if the first light-shielding film 41 and the second light-shielding film 42 are provided in a portion facing the second portion 11b in the first flexible substrate 11, The same effect as described in the display device with input function X1 shown in FIG.

  In order to further reduce the possibility that the first flexible substrate 11 is visually recognized by the user, a third light shielding film may be provided on the surface of the first flexible substrate 11.

  In addition, as shown in FIG. 2, the touch panel 4 is provided with the first light shielding film 41 and the second light shielding film 42 not only on the first flexible substrate 11 but also on a portion facing the vibrating body 5. preferable. If comprised in this way, while the possibility that the 1st flexible substrate 11 will be visually recognized by a user can be reduced, the possibility that the vibrating body 5 will be visually recognized by a user can also be reduced.

  Note that a fourth light shielding film may be provided on the surface 5 a of the vibrating body 5 in order to further reduce the possibility that the vibrating body 5 is visually recognized by the user.

  In the present embodiment, as shown in FIG. 2, since the first light shielding film 41 and the second light shielding film 42 are provided on the touch panel 4 so as to cover the second space S2, only the first flexible substrate 11 is provided. The second flexible substrate 12 can also reduce the possibility of being visually recognized by the user via the touch panel 4.

  Moreover, when the transmittance of the first light shielding film 41 is larger than the transmittance of the second light shielding film 42, the possibility that the first flexible substrate 11 is visually recognized by the user can be effectively reduced. . For example, the first light shielding film 41 is formed in white and the second light shielding film 42 is formed in black. Since the first light shielding film 41 is formed in white, the first flexible substrate 11 is likely to be visually recognized by the user only with the first light shielding film 41, but the second light shielding film 41 is formed in black. Since the light shielding film 42 is provided, the possibility that the first flexible substrate 11 is visually recognized by the user due to the second light shielding film 42 can be reduced.

  The transmittance of the first light shielding film 41 and the second light shielding film 42 can be measured by using a known spectrophotometer.

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

  In the following, an operation example of the display device X1 with an input function when a touch feeling is transmitted to the user among the tactile transmissions will be described. Of course, the present invention can also be applied to transmitting various tactile sensations such as a feeling of tracing and a feeling of touch.

  As shown in FIG. 4, when the user presses the first main surface 4 a of the touch panel 4, the vibrating body 5 detects a pressing load on the touch panel 4 (Op 1). Here, the load detection function of the vibrating body 5 will be described. That is, when the user presses the first main surface 4a of the touch panel 4, the touch panel 4 is bent downward. When the touch panel 4 is bent downward, the vibrating body 5 is also bent downward. That is, the bending amount of the vibrating body 5 changes according to the pressing load on the touch panel 4. In this embodiment, since the vibrating body 5 is a piezoelectric element, it can be converted into a voltage corresponding to the amount of bending. As a result, the pressing load on the touch panel 4 can be detected by the vibrating body 5. In addition, although the example which implement | achieved the load detection function with the vibrating body 5 was demonstrated above, you may implement | achieve with not only this but load sensors, such as a distortion sensor, for example.

  Then, when the input operation by the user is a pressing operation on the input object displayed on the display screen, the control circuit 61 determines whether or not the pressing load detected in Op1 is greater than or equal to the threshold ( Op2).

If the control circuit 61 determines that the pressing load detected at Op1 is equal to or greater than the threshold value (YES at Op2), the control circuit 61 causes the vibrating body 5 to expand and contract in the short side direction of the touch panel 4 (Op).
3). Then, the touch panel 4 is curved and vibrated in the vertical direction by the vibrating body 5 expanded and contracted in Op3 (Op4). Thereby, a pressing feeling is transmitted to the user who pressed the first main surface 4a of the touch panel 4. 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. 4 ends.

  As described above, in the display device with an input function X1, the possibility that the first flexible substrate 11 connected to the vibrating body 5 is visually recognized by the user can be reduced.
