[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and the description will be omitted as appropriate.

[0010] <First Embodiment> (Display Device 100) FIG. 1 is a schematic diagram of a display device 100 according to the first embodiment in a non-light emitting state. FIG. 2 is a perspective view when the display device 100 according to the first embodiment is disassembled. In FIG. 1, a schematic diagram of the display device 100 in a non-light emitting state where the light emitting unit 10 (described later) is not emitting light is shown. The display device 100 will be described with reference to FIGS. 1 and 2.

[0011] In the first embodiment, the display device 100 may be a display audio. The display device 100 according to the first embodiment includes a light emitting unit 10, and in addition to outputting music, a part of the display device 100 emits light.

[0012] (Light emitting unit 10) The light emitting unit 10 serves to transmit various information related to the vehicle (such as straight-ahead and left / right turn guidance) to the passengers, and to emit light in accordance with the output music. As shown in FIG. 2, the light emitting unit 10 includes a plurality of first light emitters 11. The plurality of first light emitters 11 are arranged on a base 13 and are aligned in a first direction DR1. In the first embodiment, the first direction DR1 is the width direction of the display device 100, the width direction of the vehicle, and the horizontal direction. In the first embodiment, the first light emitter 11 is an LED (Light Emitting Diode) capable of emitting light in a plurality of colors (for example, RGB colors).

[0013] In the first embodiment, the light emitting unit 10 further includes a plurality of second light emitters 12. In the first embodiment, the second light emitters 12 are arranged below the first light emitters 11. In the first embodiment, the second light emitter 12 is an LED that emits light in a single color (for example, red). The second light emitter 12 has lower power consumption and lower brightness than the first light emitter 11. Also, the number of the second light emitters 12 is smaller than that of the first light emitters 11.

[0014] A button 2 is provided outside the light emitting unit 10 in the first direction DR1. The button 2 has a function of adjusting, for example, the volume of the sound output from the display device 100.

[0015] (Display unit 30) The display device 100 further includes a display unit 30. The display unit 30 is a part that constitutes the display of the display device 100. In the first embodiment, the display unit 30 is a touch panel display. The display unit 30 is a part visible to the user. The display unit 30 has a display area 33. Various contents are displayed in the display area 33. In the first embodiment, music-related contents are displayed in the display area 33.

[0016] (Mirror unit 40) The display device 100 further includes a mirror unit 40. The mirror unit 40 is a so-called half mirror and is provided on the display unit 30. The mirror unit 40 extends in the first direction DR1. For example, when the light emitting unit 10 is in the non-light emitting state and the occupant looks at the display unit 30, the mirror unit 40 reflects the image of the occupant. The mirror unit 40 transmits at least a part of the light from the diffusion unit 50 (described later). The transmittance of the mirror unit 40 is, for example, 25%. The mirror unit 40 is provided above the display unit 30. Details of the mirror unit 40 will be described later.

[0017] (Frame unit 20) As shown in FIG. 2, the display device 100 further includes a frame unit 20 and a diffusion unit 50. The frame unit 20 serves as a housing of the display device 100. The frame unit 20 is a frame for fitting the display unit 30. The display unit 30 is attached to the side opposite to the light emitting unit 10 of the frame unit 20. The frame unit 20 is provided between the display unit 30 and the light emitting unit 10. The light emitting unit 10 is attached to the frame unit 20. The light emitting unit 10 is provided on the back side of the frame unit 20.

[0018] (Opening 21) An opening 21 is formed in the frame portion 20. The opening 21 is a gap provided in the frame portion 20 and is a slit-shaped opening. The opening 21 extends in the first direction DR1 and allows the light from the first light emitter 11 to pass through. The light emitted from the light emitting portion 10 passes through the opening 21 and then enters the mirror portion 40 provided in the display portion 30 via a diffusion portion 50 (described later). The opening 21 is arranged so as to overlap only a part of the mirror portion 40 in the first direction DR1. The length L1 of the mirror portion 40 in the first direction DR1 is larger than the length L2 of the opening 21. The length L2 of the opening 21 in the first direction DR1 is shorter than the length L3 of the display area 33 in the first direction DR1. Also, the length L3 of the display area 33 in the first direction DR1 is smaller than the length L1 of the mirror portion 40 in the first direction DR1.

[0019] (Diffusion portion 50) The diffusion portion 50 is arranged between the frame portion 20 and the display portion 30 so as to overlap the entire mirror portion 40. The diffusion portion 50 may cover the entire mirror portion 40 and be larger than the mirror portion 40 in the first direction DR1. In the first direction DR1, the length L4 of the diffusion portion 50 is larger than the length L1 of the mirror portion 40. The diffusion portion 50 diffuses the light from the first light emitter 11 that has passed through the opening 21. At least a part of the light diffused by the diffusion portion 50 enters the mirror portion 40.

[0020] FIG. 3 is a schematic enlarged view of the A region shown in FIG. 2. In FIG. 3, the mirror portion 40 is enlarged and depicted. The mirror portion 40 according to the first embodiment includes a plurality of conductor lines 31 of the display portion 30. The conductor line 31 is a conductive line provided in the display portion 30. The conductor line 31 extends in the first direction DR1. In the first embodiment, the conductor line 31 does not transmit light. In the first embodiment, the conductor line 31 contains silver or aluminum. The plurality of conductor lines 31 are arranged side by side with gaps 34 therebetween.

[0021] In the first embodiment, the touch panel included in the display unit 30 includes detection electrodes 61 (not shown) capable of detecting contact between the user and the display. The detection electrodes 61 may be mesh-shaped electrodes based on silver or aluminum. A plurality of wirings 32 (not shown) based on silver or aluminum are connected to the detection electrodes 61. The wirings 32 are wirings necessary for the touch panel included in the display unit 30 to function. In the first embodiment, the plurality of conductor lines 31 are located in the same layer as the plurality of wirings 32. In the first embodiment, the conductor lines 31 and the wirings 32 are made of the same material.

[0022] (Function and effect) As described above, the display device 100 according to the first embodiment includes a light emitting unit 10, a frame unit 20, a display unit 30, a mirror unit 40, and a diffusion unit 50. The opening 21 is arranged to overlap only a part of the mirror unit 40 in the first direction DR1. The mirror unit 40 transmits at least a part of the light from the diffusion unit 50.

[0023] FIG. 4 is a schematic diagram of the display device 100 according to the first embodiment in the light emitting state. FIG. 4 shows a schematic diagram of the display device 100 in the light emitting state where the light emitting unit 10 is emitting light. As shown in FIG. 2, the light emitted by the light emitting unit 10 (the first light emitter 11) passes through the opening 21 of the frame unit 20 and is diffused by the diffusion unit 50. Then, at least a part of the diffused light passes through the mirror unit 40.

[0024] Returning to FIG. 4, a light emitting region B and a non-light emitting region C are formed in the mirror portion 40 of the display portion 30. The light emitting region B is a region that appears to be emitting light to the user because the light diffused by the diffusing portion 50 passes through the opening 21 and is transmitted through the mirror portion 40 and emitted. The light emitting region B includes a portion of the mirror portion 40 that overlaps the opening 21. The non-light emitting region C is a region that appears to be in the state of a mirror to the user because it is blocked by the frame portion 20 and the light from the light emitting portion 10 does not reach it. The non-light emitting region C includes a portion of the mirror portion 40 that does not overlap the opening 21. Also, the region D shown in FIG. 4 is a region located between the light emitting region B and the non-light emitting region C, and is a portion of the mirror portion 40 where the opening 21 does not overlap, but a part of the light diffused by the diffusing portion 50 reaches it, so that it appears to be slightly emitting light to the user. The presence of the region D blurs the boundary between the light emitting region B and the non-light emitting region C.

[0025] Since the length L1 of the mirror portion 40 in the first direction DR1 is larger than the length L2 of the opening 21, if the diffusing portion 50 does not exist, when viewed from the display portion 30 side, the end of the opening 21 in the first direction DR1 can be seen. That is, the boundary between the light emitting region B and the non-light emitting region C can be seen, and the appearance of the display device 100 deteriorates.

[0026] However, by providing a diffusing portion 50 that is longer than the mirror portion 40 between the opening 21 and the mirror portion 40, it is possible to suppress the end of the opening 21 in the first direction DR1 (the boundary between the light emitting region B and the non-light emitting region C) from being seen. Thereby, the appearance of the display device 100 is improved.

[0027] Furthermore, the mirror portion 40 according to the first embodiment includes a plurality of conductor lines 31 of the display portion 30, and the plurality of conductor lines 31 may be arranged side by side with a gap 34 therebetween. Thereby, a half mirror having a light emitting function can be easily configured.

[0028] Furthermore, the conductor line 31 may contain silver or aluminum. Thereby, the mirror portion 40 can reflect light with a high reflectance.

[0029] Furthermore, the plurality of conductor lines 31 are located in the same layer as the plurality of wirings 32 related to the function of the touch panel included in the display unit 30, and the conductor lines 31 and the wirings 32 are made of the same material. Thus, since they can be manufactured in the same process, the display device 100 can be efficiently manufactured.

[0030] Furthermore, the light emitting unit 10 may include a second light emitter 12 that emits light in a single color. Thereby, it can emit light in a light emission pattern different from that of the first light emitter 11. For example, the second light emitter 12 can blink and emit red light while suppressing power consumption more than the first light emitter 11. Thereby, power consumption is suppressed, and for example, the operation of the security function during parking monitoring of a vehicle can be appealed to people around the vehicle.

[0031] Furthermore, the mirror unit 40 may be provided above the display unit 30. By disposing the mirror unit 40 at a position close to the line of sight of the occupant, it becomes easier for the occupant to visually recognize the mirror unit 40.

[0032] Furthermore, the display unit 30 has a display area 33 where content is displayed, and the length L2 of the opening 21 in the first direction DR1 is shorter than the length L3 of the display area 33 in the first direction DR1. Thereby, it becomes difficult for the light from the light emitting unit 10 to reach near both upper corners of the display area 33 in the first direction DR1. Therefore, even when important information is output near both upper corners of the display area 33, it is possible to avoid degrading the visibility of the occupant.

[0033] <Second Embodiment> (Display Device 100) FIG. 5 is a schematic diagram of the display device 100 according to the second embodiment in a non-light emitting state. The display device 100 according to the second embodiment includes a touch sensor unit 60 and a light emitting unit 10. The light emitting unit 10 according to the second embodiment includes a plurality of first light emitters 11 arranged in the first direction DR1, similar to the first embodiment.

[0034] The touch sensor unit 60 includes a detection electrode 61 (not shown), a wiring 32 (not shown) connected to the detection electrode 61, and a mirror unit 40. The mirror unit 40 according to the second embodiment also extends in the first direction DR1.

[0035] The detection electrode 61 (not shown) is provided in a contact detection region R1 capable of detecting contact between the user and the display. The mirror unit 40 is provided in a non-contact detection region R2 outside the contact detection region R1. The non-contact detection region R2 is a region where contact between the user and the display cannot be detected.

[0036] As shown in FIG. 2, the light emitting unit 10 according to the second embodiment can irradiate light onto the mirror unit 40 from the back of the touch sensor unit 60 (corresponding to the display unit 30 in the first embodiment). The mirror unit 40 allows a part of the light to pass through by arranging a plurality of conductor lines 31 not connected to the detection electrode 61 with a predetermined gap 34 therebetween (similar to FIG. 3). In the second embodiment, the materials of the wiring 32 and the conductor lines 31 are the same. In the second embodiment, the wiring 32 and the conductor lines 31 do not transmit light.

[0037] As shown in FIG. 2, the display device 100 according to the second embodiment may further include a frame unit 20 and a diffusion unit 50. The frame unit 20 according to the second embodiment is formed with an opening 21 extending in the first direction DR1 that allows light from the first light emitter 11 to pass through, and the light emitting unit 10 is attached thereto, similar to the first embodiment.

[0038] The diffusion unit 50 according to the second embodiment is disposed between the frame unit 20 and the touch sensor unit 60 so as to overlap the entire mirror unit 40, and diffuses the light from the first light emitter 11. The touch sensor unit 60 is attached to the side opposite to the light emitting unit 10 of the frame unit 20 and is visible to the user. In the opening 21 according to the second embodiment, similar to the first embodiment, it is arranged so as to overlap only a part of the mirror unit 40 in the first direction DR1. In the mirror unit 40 according to the second embodiment, similar to the first embodiment, at least a part of the light from the diffusion unit 50 is transmitted through.

[0039] Also in the display device 100 according to the second embodiment above, a half mirror having a light emitting function can be easily configured. Further, since the materials of the wiring 32 and the conductor line 31 are the same, the display device 100 can be efficiently manufactured.

[0040] Furthermore, the wiring 32 and the conductor line 31 may contain silver or aluminum. Thereby, the mirror portion 40 can obtain a high reflectance.

[0041] Furthermore, the wiring 32 and the conductor line 31 may be located in the same layer. Thereby, since they can be manufactured simultaneously in the same process, the manufacturing cost can be suppressed.
