Description

[Technical field]

[0001] The present disclosure relates to a display device and a method for manufacturing a display device. [Background technology]

[0002] In order to improve the safety of passengers (crew, passengers, etc.) in vehicles, trains, etc., it is necessary to reduce the harm caused to passengers by display devices installed in vehicles, trains, etc. For example, the European standard for vehicles (ECE-R21: the Economic Commission for Europe of the United Nations (UN / ECE)-Regulation No 21) is applied to interior parts of vehicles, including display devices. ECE-R21 requires high safety standards for interior parts of vehicles to protect passengers.

[0003] A display device equipped with a high-strength cover glass is known as a display device for vehicle mounting. Also, a housing capable of preventing the cover glass from scattering is known. For example, Patent Document 1 discloses a display device housing including a housing main body having side walls facing each other, and a display device holder fixed to each side wall and holding a display device having a cover glass attached to a display surface. In Patent Document 1, when an impact force that may cause the cover glass to crack is applied to the cover glass, the display device holder falls off from the housing main body before the cover glass cracks. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-026694 A Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, since the display device holder falls off from the housing body, the cover glass is prevented from cracking and the cover glass is prevented from scattering. However, since the display device and the display device holder fall off from the housing body, there is a risk that pieces of the components constituting the display device will scatter inside the vehicle through the gap between the display device holder or the display device and the housing body.

[0006] The present disclosure has been made in consideration of the above circumstances, and has an object to provide a display device that is highly safe for users and a method for manufacturing a display device. [Means for solving the problem]

[0007] In order to achieve the above object, a display device according to a first aspect of the present disclosure comprises: At least one display unit; a cover disposed on a display surface side of the at least one display unit; a housing that houses the at least one display unit; a first shatterproof portion provided on the cover and extending between the display unit and an inner surface of the housing; The first shatterproof portion is inclined at an acute angle with respect to the rear surface of the display unit.

[0008] A method for manufacturing a display device according to a second aspect of the present disclosure includes: A first step of attaching a shatterproof part to a main surface of the cover; and a second step of providing a display unit on the main surface of the cover to which the shatterproof part is attached, the shatterproof portion extends in a rear direction of the display unit and is inclined toward the display unit with respect to the rear direction of the display unit; In the second step, the display unit is provided on the main surface of the cover in a state in which the shatterproof portion is pressed against a region opposite to a region in which the display unit is provided.

[0009] A method for manufacturing a display device according to a third aspect of the present disclosure includes: A first step of providing a display unit on a main surface of a cover; and a second step of attaching a shatterproof portion to the cover on which the display unit is provided, the shatterproof portion extending in a rear direction of the display unit and inclined toward the display unit with respect to the rear direction of the display unit. Effect of the Invention

[0010] According to the present disclosure, since the first shatterproof part is inclined at an acute angle with respect to the back surface direction of the display unit, it is possible to prevent the members constituting the display unit from scattering, thereby reducing the possibility of the user being seriously injured by scattered objects and increasing the safety of the display device for the user.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, a display device according to an embodiment will be described with reference to the drawings.

[0013] <Embodiment 1> A display device 10 according to this embodiment will be described with reference to Figs. 1 to 5. The display device 10 is mounted on vehicles, aircraft, home appliances, furniture, etc. In this embodiment and the following embodiments, the display device 10 will be described taking a case where it is mounted on a vehicle as an example. A passenger in the vehicle corresponds to a user (observer).

[0014] As shown in FIG. 1, the display device 10 is disposed in an opening 610 of an instrument panel 600 of a vehicle. The instrument panel 600 is formed of, for example, resin. For ease of understanding, in this specification, the longitudinal direction (to the right of the paper) of the display device 10 in FIG. 1 is described as the +X direction, the lateral direction (toward the back of the paper) is described as the +Y direction, and the direction perpendicular to the +X direction and the +Y direction (upward of the paper, toward the passenger) is described as the +Z direction. In addition, the +Z direction and a direction parallel to the +Z direction are described as the front direction of the display unit 100 described later, and the -Z direction and a direction parallel to the -Z direction are described as the back direction of the display unit 100. For ease of understanding, hatching of the chassis 132, the bezel 136, and the like is omitted in FIG. 1. Hatching may also be omitted in the following figures.

[0015] The display device 10 includes a display unit 100, a cover 200, a housing 300, and a first shatterproof part 400. The display unit 100 displays characters, images, etc. The cover 200 protects the display unit 100. The housing 300 houses the display unit 100. The first shatterproof part 400 prevents glass fragments, resin fragments, metal fragments, etc. from scattering when the display unit 100 is broken.

[0016] As shown in FIG. 1, the display unit 100 of the display device 10 includes a liquid crystal display panel 110, a backlight 120, and a unit housing 130.

[0017] The liquid crystal display panel 110 of the display unit 100 is, for example, a known transmissive horizontal electric field type liquid crystal display panel. The liquid crystal display panel 110 is active matrix driven by TFTs (Thin Film Transistors). The liquid crystal display panel 110 modulates light from a backlight 120 to display characters, images, etc. The liquid crystal display panel 110 has a display area 111 and a peripheral area 112. The display area 111 is an area in which pixels are arranged in a matrix and in which characters, images, etc. can be displayed. The peripheral area 112 is an area in which wiring, driving circuits, etc. are arranged.

[0018] 2, the liquid crystal display panel 110 includes a TFT substrate 114, a counter substrate 115, liquid crystal 116, a first polarizing plate 117, and a second polarizing plate 118. The TFT substrate 114 and the counter substrate 115 sandwich the liquid crystal 116. The first polarizing plate 117 is provided on the TFT substrate 114, and the second polarizing plate 118 is provided on the counter substrate 115.

[0019] The TFT substrate 114 is, for example, a glass substrate. The TFT substrate 114 is located on the -Z side. A TFT for selecting pixels, a common electrode, a pixel electrode, a driving circuit, an alignment film for orienting the liquid crystal 116, and the like are provided on a main surface 114a of the TFT substrate 114 facing the liquid crystal 116 (none of which are shown). A first polarizing plate 117 is provided on a main surface 114b of the TFT substrate 114 opposite to the main surface 114a.

[0020] The counter substrate 115 is located on the +Z side and faces the TFT substrate 114. The counter substrate 115 is attached to the TFT substrate 114 with a sealant 119. The counter substrate 115 is, for example, a glass substrate. A color filter, a black matrix, an alignment film for orienting the liquid crystal 116, and the like are provided on a main surface 115a of the counter substrate 115 facing the liquid crystal 116 (none of which are shown). A second polarizing plate 118 is provided on a main surface 115b of the counter substrate 115 opposite to the main surface 115a.

[0021] The TFT substrate 114 and the counter substrate 115 are formed of, for example, non-alkali glass. Since non-alkali glass does not contain alkaline components such as sodium or potassium, it is possible to prevent the liquid crystal 116 from being contaminated by alkaline components, which may cause deterioration in the display quality of the liquid crystal display panel 110.

[0022] The liquid crystal 116 is sandwiched between the TFT substrate 114 and the counter substrate 115. The liquid crystal 116 is, for example, a positive type nematic liquid crystal. The liquid crystal 116 is initially aligned in a direction parallel to the main surface 114a of the TFT substrate 114 by an alignment film. Furthermore, the liquid crystal 116 rotates in a plane parallel to the main surface 114a of the TFT substrate 114 when a voltage is applied.

[0023] The first polarizer 117 is provided on the main surface 114b of the TFT substrate 114, and the second polarizer 118 is provided on the main surface 115b of the counter substrate 115. One of the transmission axes of the first polarizer 117 and the second polarizer 118 is arranged parallel to the initial alignment direction of the liquid crystal 116, and the transmission axis of the first polarizer 117 and the transmission axis of the second polarizer 118 are perpendicular to each other. In this embodiment, the main surface 118a on the +Z side of the second polarizer 118 corresponds to the display surface 110a of the liquid crystal display panel 110 (i.e., the display surface 110a of the display unit 100).

[0024] 1, the backlight 120 of the display unit 100 is disposed on the rear side (-Z side) of the liquid crystal display panel 110. The backlight 120 is a light source for the liquid crystal display panel 110. The backlight 120 emits white light to the liquid crystal display panel 110. The backlight 120 includes white LED (Light Emitting Diode) elements, a reflective sheet, a diffusion sheet, a light guide plate, a lighting circuit, and the like (none of which are shown). The light guide plate is formed, for example, from a light-transmitting acrylic resin (PMMA: Poly Methyl Methacrylate).

[0025] The unit housing 130 of the display unit 100 houses the liquid crystal display panel 110 and the backlight 120. The unit housing 130 has a chassis 132 and a bezel 136. It is to be noted that the bezel 136 does not necessarily have to be provided on the unit housing 130.

[0026] The chassis 132 has a box shape and is made of resin or metal, and houses the liquid crystal display panel 110 and the backlight 120 inside.

[0027] The bezel 136 has a box shape and has an opening 138 at a bottom 137. The bezel 136 is formed from, for example, metal. The bezel 136 covers the chassis 132 with the bottom 137 facing the +Z side, and protects the peripheral portion 112 of the liquid crystal display panel 110. The display area 111 of the liquid crystal display panel 110 is exposed from the opening 138.

[0028] The cover 200 of the display device 10 is disposed on the display surface 110a side (+Z side) of the display unit 100 to protect the display unit 100. The cover 200 is formed in a flat plate shape from a light-transmitting resin, glass, or the like. When the cover 200 is formed from glass, the cover 200 is generally formed from tempered glass, but the cover 200 may be formed from soda-lime glass. The outer shape (X direction, Y direction) of the cover 200 is larger than the outer shape (X direction, Y direction) of the display unit 100. Therefore, as shown in FIG. 1, in a cross-sectional view, the cover 200 protrudes outward from the outer shape of the display unit 100. In this embodiment, the cover 200 is attached to a side plate 320 of the housing 300 described later via an adhesive member 202. A light-transmitting adhesive 204 (for example, OCA: Optical Clear Adhesive) is filled between the cover 200 and the liquid crystal display panel 110.

[0029] The housing 300 of the display device 10 has a box shape and houses the display unit 100. The housing 300 is made of, for example, metal. The housing 300 has a bottom plate 310 and a side plate 320. In this embodiment, the housing 300 supports the display unit 100 by a support portion 312 of the bottom plate 310. In addition, the side plate 320 is adhered to an inner wall surface 610a of an opening 610 of an instrument panel 600 by an adhesive (not shown). In this way, the display device 10 is fixed to the opening 610 of the instrument panel 600.

[0030] As shown in Figures 1, 3, and 4, the four first shatterproof parts 400 of the display device 10 are provided on the main surface 200a of the cover 200 facing the display unit 100. When viewed in plan, the four first shatterproof parts 400 extend along the long sides (X direction) or short sides (Y direction) of the display unit 100, as shown in Figure 3, and surround the display unit 100 in a frame shape. Note that in Figures 3 and 4, the display unit 100 is illustrated in a simplified form for ease of understanding. In the following figures, the display unit 100 may also be simplified.

[0031] The first shatterproof part 400 has a first fixing part 410 and a first shielding part 420. The first fixing part 410 is attached to the main surface 200a of the cover 200 via an adhesive member (not shown). In this embodiment, as shown in Figs. 1 and 3, the first fixing part 410 is attached to the main surface 200a of the cover 200 at a portion that protrudes outward beyond the side surface 136a of the display unit 100. The first fixing part 410 is disposed between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300.

[0032] 1, the first shielding portion 420 extends from the first fixing portion 410 between the side surface 136a (side surface 136a of the bezel 136) of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300. Also, as shown in FIG. 4, the first shielding portion 420 is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100 (a straight line extending parallel to the -Z direction and passing through a joint 425 between the first fixing portion 410 and the first shielding portion 420). When viewed in cross section, the first shatterproof portion 400 can also be expressed as having an L-shape in which the first shielding portion 420 is inclined at an acute angle with respect to the rear direction of the display unit 100.

[0033] The first shatterproof part 400 is made of synthetic resin, metal, rubber, etc. In this embodiment, the first shatterproof part 400 is made of synthetic resin. Also, the first shatterproof part 400 is arranged such that the joint part 425 (the L-shaped bent part) faces the outer periphery of the cover 200, as shown in FIG.

[0034] In this embodiment, when an impact is applied to the display device 10 (cover 200) from the passenger side (+Z side) and the display device 10 is damaged, the first shielding portion 420 of the first shatterproof portion 400 extends between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300, so that the first shielding portion 420 closes the gap between the cover 200 and the display unit 100 (bezel 136) as shown in Fig. 5. This makes it possible to prevent glass fragments, resin fragments, metal fragments, etc. from passing between the cover 200 and the display unit 100 and scattering into the vehicle.

[0035] In addition, since the first shielding portion 420 of the first shatterproof portion 400 is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100, the gap between the side surface 136a of the display unit 100 and the first shielding portion 420 can be narrowed. Furthermore, even if the portion of the cover 200 to which the first shatterproof portion 400 (first fixing portion 410) is attached is deformed, since the first shielding portion 420 is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100, the first shielding portion 420 falls toward the inner side surface 320a of the housing 300, and the gap between the side surface 136a of the display unit 100 and the first shielding portion 420 can be prevented from widening. Therefore, glass pieces, resin pieces, metal pieces, etc. can also be prevented from scattering from between the first shielding portion 420 and the display unit 100. In other words, the first shatterproof section 400 is particularly effective in preventing the scattering of glass pieces of the TFT substrate 114 and the opposing substrate 115, as well as resin and metal pieces of the light guide plate, chassis 132, bezel 136, etc., which are generated from the display unit 100 due to damage to the display device 10.

[0036] As described above, the first shielding portion 420 of the first shatterproof portion 400 extends between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300, and is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100, thereby preventing glass fragments, resin fragments, metal fragments, etc. from scattering inside the vehicle due to breakage. This allows the display device 10 to be safer for the user.

[0037] <Embodiment 2> In the first embodiment, the first shatterproof part 400 is made of synthetic resin. The first shatterproof part 400 may be made of metal, rubber, or the like having elasticity (springiness). The configuration of the display device 10 of this embodiment is similar to that of the display device 10 of the first embodiment, except for the configuration of the first shatterproof part 400. Here, the first shatterproof part 400 of this embodiment will be described.

[0038] The first shatterproof part 400 of this embodiment is formed from a metal thin plate having elasticity (springiness). The first shatterproof part 400 of this embodiment has an elastic restoring force in the direction in which the first fixing part 410 and the first shielding part 420 close. In this embodiment, the first shielding part 420 of the first shatterproof part 400 abuts against the display unit 100 (side surface 136a) as shown in FIG. 6, and presses the display unit 100 toward the center of the display unit 100. The other configurations of the first shatterproof part 400 of this embodiment are the same as those of the first shatterproof part 400 of the first embodiment. Note that, although the first shielding part 420 is illustrated in a flat shape in FIG. 6, the first shielding part 420 may be curved due to elasticity.

[0039] In this embodiment, since the first shielding part 420 of the first shatterproof part 400 presses against the display unit 100, even if the display device 10 is damaged, the first shielding part 420 can maintain a state of contact with the display unit 100 as shown in Fig. 7. Therefore, a gap is less likely to occur between the display unit 100 and the first shielding part 420, and it is possible to further prevent glass fragments, metal fragments, etc., caused by damage from scattering inside the vehicle.

[0040] Next, a manufacturing method of the display device 10 of this embodiment will be described with reference to Fig. 8 and Fig. 9. Fig. 8 is a flowchart showing the manufacturing method of the display device 10. The manufacturing method of the display device 10 includes a step of attaching the first shatterproof part 400 to the main surface 200a of the cover 200 (step S110), a step of providing the display unit 100 on the main surface 200a of the cover 200 to which the first shatterproof part 400 has been attached (step S120), and a step of housing the display unit 100 in the housing 300 and attaching the cover 200 to the housing 300 (step S130).

[0041] In step S110, the first shatterproof part 400 formed from an elastic metal is attached to the main surface 200a of the cover 200. Specifically, the first fixing part 410 of the first shatterproof part 400 is adhered to the main surface 200a of the cover 200 with an adhesive member (for example, double-sided tape).

[0042] In step S120, as shown in FIG. 9, a jig (not shown) is used to press the first shielding portion 420 of the first shatterproof portion 400 to the opposite side to the area where the display unit 100 is provided, to secure a space for providing the display unit 100, and with the first shielding portion 420 pressed, the display unit 100, which has the adhesive 204 applied to its display surface 110a, is provided on the main surface 200a of the cover 200. Then, the adhesive 204 is cured to bond the display unit 100 and the cover 200 together. After the adhesive 204 is cured, the pressure on the first shielding portion 420 is released, and the first shielding portion 420 is brought into contact with the display unit 100. This achieves a state in which the first shielding portion 420 of the first shatterproof portion 400 presses the display unit 100.

[0043] In step S130, the display unit 100 attached to the cover 200 is housed in the housing 300, and the cover 200 is attached to the side plate 320 of the housing 300 by the adhesive member 202. In this manner, the display device 10 can be manufactured.

[0044] As described above, since the first shielding part 420 of the first shatterproof part 400 presses against the display unit 100, even if the display device 10 is broken, the first shielding part 420 can maintain a state of abutting against the display unit 100, and glass fragments, resin fragments, metal fragments, etc. caused by the breakage can be further prevented from scattering inside the vehicle. This makes the display device 10 safer for the user.

[0045] <Embodiment 3> The first fixing portion 410 of the first shatterproof portion 400 may be located between the cover 200 and the side plate 320 of the housing 300. The configuration of the display device 10 of this embodiment is similar to the configuration of the display device 10 of embodiment 1, except for the configuration and arrangement of the first shatterproof portion 400. Here, the first shatterproof portion 400 of this embodiment will be described.

[0046] The first shatterproof part 400 of this embodiment has a first fixing part 410 and a first shielding part 420, similar to the first shatterproof part 400 of the first embodiment. The first shatterproof part 400 of this embodiment is formed of a synthetic resin, similar to the first shatterproof part 400 of the first embodiment.

[0047] In this embodiment, the first fixing portion 410 of the first shatterproof portion 400 is located between the cover 200 and the side plate 320 of the housing 300, as shown in Fig. 10. Specifically, the first fixing portion 410 is located between the cover 200 and the side plate 320 of the housing 300, and is adhered to the upper surface 320b of the side plate 320 of the housing 300 by a first adhesive member 502, and is adhered to the main surface 200a of the cover 200 by a second adhesive member 504.

[0048] The first adhesive member 502 and the second adhesive member 504 are, for example, double-sided tape. In this embodiment, the adhesive force of the second adhesive member 504 bonding the main surface 200a of the cover 200 to the first fixing portion 410 is greater than the adhesive force of the first adhesive member 502 bonding the first fixing portion 410 to the upper surface 320b of the side plate 320 of the housing 300. This allows the first shatterproof portion 400 to remain attached to the main surface 200a of the cover 200 even if the display device 10 is damaged.

[0049] Similar to the first shielding portion 420 of the first shatterproof portion 400 in the first embodiment, the first shielding portion 420 extends between the side surface 136a of the display unit 100 and the inner side surface 320a of the side panel 320 of the housing 300. In addition, the first shielding portion 420 is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100.

[0050] Other configurations of the first shatter prevention unit 400 of this embodiment are similar to those of the first shatter prevention unit 400 of the first embodiment.

[0051] 11, when the display device 10 is damaged by an impact from the passenger side (+Z side), the adhesive force bonding the main surface 200a of the cover 200 to the first fixing part 410 is greater than the adhesive force bonding the first fixing part 410 to the upper surface 320b of the side plate 320 of the housing 300, so that the first shatterproof part 400 remains on the main surface 200a of the cover 200, and the first shielding part 420 closes the gap between the cover 200 and the housing 300 (side plate 320). Therefore, glass fragments, resin fragments, metal fragments, etc. can be prevented from passing between the cover 200 and the housing 300 and scattering into the vehicle.

[0052] Furthermore, in this embodiment, the first shielding portion 420 seals the gap between the cover 200 and the housing 300 (side panel 320), so that even if glass fragments, resin fragments, metal fragments, etc. are generated inside the display device 10 due to damage to the display device 10 and appear on the rear side of the display unit 100, these fragments can be prevented from scattering inside the vehicle.

[0053] As described above, the display device 10 of this embodiment can prevent glass fragments, resin fragments, metal fragments, etc. from scattering inside the vehicle due to breakage, thereby improving safety for the user. Furthermore, since the first fixing portion 410 of the first shatterproof portion 400 is located on the side plate 320 of the housing 300, the space required for providing the first shatterproof portion 400 can be reduced, and the distance between the display unit 100 and the side plate 320 of the housing 300 can be narrowed.

[0054] <Embodiment 4> In the first to third embodiments, the first shielding portion 420 of the first shatterproof portion 400 is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100. The first shielding portion 420 may be inclined at an acute angle toward the inner side surface 320a of the housing 300 with respect to the rear direction of the display unit 100. The configuration of the display device 10 of this embodiment is similar to the configuration of the display device 10 of the first embodiment, except for the configuration of the first shatterproof portion 400. The first shatterproof portion 400 of this embodiment will be described.

[0055] The first shatterproof part 400 of this embodiment has a first fixing part 410 and a first shielding part 420, similar to the first shatterproof part 400 of embodiment 1. The first shatterproof part 400 of this embodiment is made of synthetic resin, similar to the first shatterproof part 400 of embodiment 1, and is provided on the main surface 200a of the cover 200.

[0056] The first fixing portion 410 is attached to the main surface 200a of the cover 200 via an adhesive member, as in the first embodiment. The first shielding portion 420 extends from the first fixing portion 410 between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300, and is inclined at an acute angle toward the inner surface 320a of the housing 300 with respect to the rear direction of the display unit 100, as shown in FIG.

[0057] Other configurations of the first shatter prevention unit 400 of this embodiment are similar to those of the first shatter prevention unit 400 of the first embodiment.

[0058] 13, if the display device 10 is broken by an impact from the passenger side (+Z side), the first shielding portion 420, which is inclined at an acute angle toward the inner surface 320a of the housing 300 with respect to the back direction of the display unit 100, closes the gap between the cover 200 and the housing 300 (side plate 320). This makes it possible to prevent glass fragments, metal fragments, etc. from passing between the cover 200 and the housing 300 and scattering into the vehicle.

[0059] As described above, the display device 10 of the present embodiment can also prevent glass fragments, metal fragments, and the like from scattering inside the vehicle due to breakage, thereby improving safety for the user.

[0060] <Embodiment 5> In the first embodiment, the housing 300 houses the display unit 100. The housing 300 may house a member other than the display unit 100. Furthermore, in the multiple first shatterproof parts 400, the heights (positions) of the ends 422 of the first shielding parts 420 from the cover 200 may be different.

[0061] The display device 10 of this embodiment includes a display unit 100, a cover 200, a housing 300, three first shatterproof units 400A, one first shatterproof unit 400B, and an imaging unit 700. The configurations of the display unit 100 and the cover 200 of this embodiment are similar to those of the first embodiment, so the imaging unit 700, the housing 300, the first shatterproof unit 400A, and the first shatterproof unit 400B of this embodiment will be described below.

[0062] The imaging unit 700 captures images of passengers, the interior of the vehicle, etc. The imaging unit 700 is housed in a housing 300 as shown in Fig. 14. The imaging unit 700 has a light source 710 and an imaging element 720. The light source 710 and the imaging element 720 are disposed in an imaging unit housing 730.

[0063] The light source 710 is a white LED element, an infrared LED element, etc. The imaging element 720 is a CCD (Charge Coupled Device) image sensor, an infrared image sensor, etc.

[0064] The housing 300 of this embodiment houses the display unit 100 and the imaging section 700. In the housing 300, the display unit 100 and the imaging section 700 are arranged side by side in the X direction. Specifically, the display unit 100 is located on the +X side, and the imaging section 700 is located on the -X side. Therefore, when viewed in cross section on the XZ plane, as shown in FIG. 14, the center line DZ that bisects the display unit 100 is shifted in the +X direction with respect to the center line CZ that bisects the cover 200. The other configurations of the housing 300 of this embodiment are similar to those of the housing 300 of the first embodiment.

[0065] The first shatterproof portion 400A and the first shatterproof portion 400B, like the first shatterproof portion 400 in the first to fourth embodiments, prevent glass fragments, resin fragments, metal fragments, and the like from scattering when the display unit 100 is broken. The first shatterproof portion 400A and the first shatterproof portion 400B are made of synthetic resin, like the first shatterproof portion 400 in the first embodiment. As shown in FIGS. 14 and 15, three first shatterproof portions 400A and one first shatterproof portion 400B are provided on the main surface 200a of the cover 200, respectively.

[0066] 15, two first shatterproof parts 400A extending along the long side (X direction) of the display unit 100 are disposed on either side of the display unit 100. One first shatterproof part 400A extending along the short side (Y direction) of the display unit 100 is disposed on the +X side of the display unit 100. One first shatterproof part 400B extending along the short side (Y direction) of the display unit 100 is disposed on the -X side of the imaging unit 700 and the display unit 100. The three first shatterproof parts 400A and one first shatterproof part 400B surround the display unit 100 and the imaging unit 700.

[0067] The first shatterproof part 400A and the first shatterproof part 400B have a first fixing part 410 and a first shielding part 420, similar to the first shatterproof part 400 of the first to fourth embodiments. The first fixing part 410 is attached to the main surface 200a of the cover 200 via an adhesive member. As shown in FIG. 14, the first shielding part 420 of the first shatterproof part 400A extends from the first fixing part 410 between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300. The first shielding part 420 of the first shatterproof part 400A is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100, similar to the first shielding part 420 of the first to third embodiments. The first shielding portion 420 of the first shatterproof portion 400B extends from the first fixing portion 410 between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300, and the first shielding portion 420 of the first shatterproof portion 400B and the side surface 136a of the display unit 100 sandwich the imaging portion 700. The first shielding portion 420 of the first shatterproof portion 400B is inclined at an acute angle toward the inner surface 320a of the housing 300 with respect to the rear direction of the display unit 100, similar to the first shielding portion 420 of the fourth embodiment.

[0068] In this embodiment, the height H2 of the end 422 (the end not connected to the fixed part) of the first shielding part 420 of the first shatterproof part 400B from the cover 200 is different from the height H1 of the end 422 of the first shielding part 420 of the first shatterproof part 400A from the cover 200. Specifically, the height H2 of the end 422 of the first shielding part 420 of the first shatterproof part 400B from the cover 200 is higher than the height H1 of the end 422 of the first shielding part 420 of the first shatterproof part 400A from the cover 200. The height of the end 422 from the cover 200 is also expressed as the position of the end 422 in the rear direction of the display unit 100 with respect to the cover 200.

[0069] In this embodiment, the center line DZ that bisects the display unit 100 is shifted in the +X direction from the center line CZ that bisects the cover 200. Therefore, when an impact is applied to the display unit 100 through the cover 200 and the display device 10 is damaged, as shown in FIG. 16, the gap D2 between the cover 200 on the -X side and the side plate 320 of the housing 300 is wider than the gap D1 between the cover 200 on the +X side and the side plate 320 of the housing 300. On the other hand, the height H2 of the end 422 of the first shielding part 420 of the first shatterproof part 400B arranged on the -X side of the display unit 100 and the imaging part 700 is higher than the height H1 of the end 422 of the first shielding part 420 of the first shatterproof part 400A. Therefore, the first shielding part 420 of the first shatterproof part 400B can easily close the wide gap D2 and prevent glass fragments, metal fragments, etc. from scattering into the vehicle.

[0070] As described above, the display device 10 of the present embodiment can also prevent glass fragments, metal fragments, and the like from scattering inside the vehicle due to breakage, thereby improving safety for the user.

[0071] <Embodiment 6> In the first embodiment, the display device 10 includes one display unit 100. The display device 10 may include a plurality of display units 100. The display device 10 may also include a second shatterproof portion 440 extending between the two juxtaposed display units 100.

[0072] The display device 10 of this embodiment includes two display units 100, a cover 200, a housing 300, four first shatterproof units 400, and two second shatterproof units 440. Since the configuration of the cover 200 of this embodiment is the same as that of embodiment 1, the display units 100, the housing 300, the first shatterproof units 400, and the second shatterproof units 440 of this embodiment will be described below.

[0073] 17, in this embodiment, two display units 100 are arranged side by side in the X direction, and the two display units 100 are housed in a housing 300. A light-transmitting adhesive 204 is filled between the cover 200 and each of the display units 100. The other configurations of the display unit 100 of this embodiment are the same as those of the first embodiment.

[0074] The housing 300 of this embodiment houses two display units 100. Other configurations of the housing 330 of this embodiment are the same as those of the first embodiment.

[0075] 18, in plan view, the two first shatterproof units 400 of this embodiment extend in the X direction and sandwich two display units 100 therebetween. The other two first shatterproof units 400 of this embodiment extend along the Y direction and sandwich two display units 100 therebetween. The four first shatterproof units 400 of this embodiment surround the two display units 100 in a frame shape. The other configuration of the first shatterproof unit 400 of this embodiment is the same as that of embodiment 1.

[0076] The second shatterproof section 440, like the first shatterproof section 400, prevents glass fragments, resin fragments, metal fragments, and the like from scattering due to breakage of the display unit 100. The second shatterproof section 440, like the first shatterproof section 400, is provided on the main surface 200a of the cover 200. When viewed in a plan view, the second shatterproof section 440 is disposed between the two juxtaposed display units 100. In this embodiment, the two second shatterproof sections 440 extending in the Y direction are disposed side by side in the X direction between the two juxtaposed display units 100.

[0077] The second shatterproof portion 440 is formed from synthetic resin, metal, rubber, or the like, similar to the first shatterproof portion 400. The second shatterproof portion 440 has a second fixing portion 442 and a second shielding portion 444. The second fixing portion 442 is attached to the main surface 200a of the cover 200 via an adhesive member.

[0078] 17, the second shielding portion 444 extends from the second fixing portion 442 between the two display units 100. The second shielding portion 444 of the second shatterproof portion 440 located on the -X side is inclined at an acute angle toward the side surface 136a of the display unit 100 located on the -X side with respect to the rear direction of the display unit 100 located on the -X side. The second shielding portion 444 of the second shatterproof portion 440 located on the +X side is inclined at an acute angle toward the side surface 136a of the display unit 100 located on the +X side with respect to the rear direction of the display unit 100 located on the +X side.

[0079] In this embodiment, similar to embodiment 1, the first shatterproof section 400 prevents glass shards, resin shards, metal shards, etc. from scattering into the vehicle through the gap between the cover 200 and the display unit 100. In addition, when viewed from above, the four first shatterproof sections 400 surround the two display units 100 in a frame shape, so that even if an impact is applied between the two display units 100, it is possible to prevent glass shards, resin shards, metal shards, etc. from scattering into the vehicle.

[0080] If the display device 10 is damaged, the second shielding portion 444 of the second shatterproof portion 440 extends between the two display units 100, and therefore the second shielding portion 444 blocks the gap between the cover 200 and the display unit 100. This further prevents glass fragments, resin fragments, metal fragments, etc. from passing between the cover 200 and the display unit 100 and scattering into the vehicle.

[0081] Furthermore, since the second shielding portion 444 is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100, the gap between the side surface 136a of the display unit 100 and the second shielding portion 444 can be narrowed. Even if the cover 200 is deformed, since the second shielding portion 444 is inclined at an acute angle toward the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100, the gap between the side surface 136a of the display unit 100 and the second shielding portion 444 can be prevented from widening. Therefore, it is also possible to prevent glass pieces, resin pieces, metal pieces, etc. from scattering from between the second shielding portion 444 and the display unit 100.

[0082] As described above, the display device 10 of the present embodiment can further prevent glass fragments, metal fragments, and the like from scattering inside the vehicle due to breakage, thereby improving safety for the user.

[0083] <Embodiment 7> In the first embodiment, the display unit 100 and the cover 200 are flat. The display unit 100 and the cover 200 may be curved.

[0084] Similar to the display device 10 of the first embodiment, the display device 10 of the present embodiment includes a display unit 100, a cover 200, a housing 300, and four first shatterproof parts 400. Since the configuration of the housing 300 of the present embodiment is similar to that of the first embodiment, the display unit 100, the cover 200, and the first shatterproof parts 400 of the present embodiment will be described below.

[0085] The display unit 100 and the cover 200 of this embodiment are concavely curved toward the +Z direction (toward the passenger) as shown in Fig. 19. Other configurations of the display unit 100 and the cover 200 of this embodiment are the same as those of the first embodiment.

[0086] The first shatterproof section 400 of this embodiment, like the first shatterproof section 400 of embodiment 1, prevents glass fragments, resin fragments, metal fragments, and the like from scattering due to breakage of the display unit 100. Also, like the first shatterproof section 400 of embodiment 1, the first shatterproof section 400 of this embodiment has a first fixing section 410 and a first shielding section 420. The first fixing section 410 of this embodiment is attached to the main surface 200a of the cover 200 via an adhesive member.

[0087] Similar to the first shielding portion 420 of the first embodiment, the first shielding portion 420 of the present embodiment extends from the first fixing portion 410 between the side surface 136a of the display unit 100 and the inner side surface 320a of the side plate 320 of the housing 300. Furthermore, when viewed in cross section, the first shielding portion 420 of the present embodiment is inclined with respect to the side surface 136a of the display unit 100 such that the distance S between the first shielding portion 420 and the side surface 136a of the display unit 100 narrows toward the rear of the display unit 100, as shown in Figs.

[0088] In this embodiment, the first shielding portion 420 extends from the first fixing portion 410 between the side surface 136a of the display unit 100 and the inner side surface 320a of the side plate 320 of the housing 300, and therefore, similarly to the first embodiment, the first shielding portion 420 closes the gap between the cover 200 and the display unit 100, and it is possible to prevent glass fragments, resin fragments, metal fragments, and the like from scattering into the vehicle. In addition, since the first shielding portion 420 is inclined in a direction such that the distance S between the first shielding portion 420 and the side surface 136a of the display unit 100 narrows toward the rear surface of the display unit 100, it is possible to narrow the gap between the side surface 136a of the display unit 100 and the first shielding portion 420, and it is possible to further prevent glass fragments, resin fragments, metal fragments, and the like from scattering into the vehicle.

[0089] In this embodiment, the side surface 136a of the display unit 100 is inclined toward the inner side surface 320a of the housing 300 with respect to the rear direction of the display unit 100, but the inclination direction of the side surface 136a of the display unit 100 with respect to the rear direction of the display unit 100 is arbitrary. The side surface 136a of the display unit 100 does not have to be inclined with respect to the rear direction of the display unit 100. In this embodiment, the first shielding portion 420 abuts against the side surface 136a of the display unit 100. The angle θ formed by the first shielding portion 420 and the side surface 136a of the display unit 100 is an acute angle that opens toward the passenger side (+Z direction) as shown in FIG. 20.

[0090] <Embodiment 8> In the seventh embodiment, the display unit 100 and the cover 200 are curved concavely toward the +Z direction (passenger side). The display unit 100 and the cover 200 may be curved convexly toward the +Z direction (passenger side).

[0091] The display device 10 of this embodiment includes a display unit 100, a cover 200, a housing 300, and four first shatterproof parts 400, like the display device 10 of the first embodiment.

[0092] The display unit 100 and the cover 200 of this embodiment are curved in a convex shape toward the +Z direction (passenger side) as shown in Fig. 21. The cover 200 of this embodiment is attached to the inner surface 320a of the housing 300 by an adhesive member (not shown). Other configurations of the display unit 100 and the cover 200 of this embodiment are the same as those of the first embodiment.

[0093] The housing 300 of this embodiment houses the display unit 100. When viewed in cross section, the housing 300 of this embodiment has a box shape with an opening wider than the bottom plate 310. In the housing 300 of this embodiment, the side plate 320 opens toward the outside of the housing 300, and the side plate 320 (inner surface 320a) is inclined toward the outside of the housing 300 with respect to the rear direction of the display unit 100.

[0094] Similar to the first shatterproof section 400 of the first embodiment, the first shatterproof section 400 of the present embodiment prevents glass fragments, resin fragments, metal fragments, and the like from scattering due to breakage of the display unit 100. The first shatterproof section 400 of the present embodiment also includes a first fixing section 410 and a first shielding section 420. The first fixing section 410 of the present embodiment is attached to the main surface 200a of the cover 200 via an adhesive member.

[0095] Similar to the first shielding portion 420 of the first embodiment, the first shielding portion 420 of the present embodiment extends from the first fixing portion 410 between the side surface 136a of the display unit 100 and the inner surface 320a of the side panel 320 of the housing 300. When viewed in cross section, the first shielding portion 420 of the present embodiment is inclined with respect to the inner surface 320a of the housing 300 such that the distance T between the first shielding portion 420 and the inner surface 320a narrows toward the back of the display unit 100, as shown in Figs.

[0096] In this embodiment, the first shielding portion 420 extends from the first fixing portion 410 between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300, and therefore, similarly to the first embodiment, the first shielding portion 420 closes the gap between the cover 200 and the display unit 100, and it is possible to prevent glass fragments, resin fragments, metal fragments, and the like from scattering into the vehicle. In addition, since the first shielding portion 420 is inclined in a direction such that the distance T between the first shielding portion 420 and the inner surface 320a narrows toward the rear surface of the display unit 100, it is possible to narrow the gap between the inner surface 320a and the first shielding portion 420, and it is possible to further prevent glass fragments, resin fragments, metal fragments, and the like from scattering into the vehicle.

[0097] In this embodiment, the side plate 320 (inner surface 320a) of the housing 300 is inclined outward from the housing 300 with respect to the back surface direction of the display unit 100, but the inclination direction of the side plate 320 of the housing 300 with respect to the back surface direction is arbitrary. The side plate 320 of the housing 300 does not have to be inclined with respect to the back surface direction of the display unit 100. The angle φ between the first shielding portion 420 and the inner surface 320a is an acute angle that opens toward the passenger side (+Z direction) as shown in FIG.

[0098] <Modification> Although the embodiments have been described above, the present disclosure can be modified in various ways without departing from the spirit and scope of the present disclosure.

[0099] For example, the display unit 100 may include an organic EL (Electro Luminescence) display panel instead of the liquid crystal display panel 110 and the backlight 120. Furthermore, the display unit 100 does not need to include the unit housing .

[0100] The display device 10 may include a touch panel between the cover 200 and the display unit 100. The touch panel is attached to each of the cover 200 and the liquid crystal display panel 110 of the display unit 100 by, for example, a light-transmitting adhesive.

[0101] In the embodiment, the display device 10 includes a plurality of first shatterproof portions 400, 400A, 400B, but it is sufficient that the display device 10 includes at least one first shatterproof portion 400, 400A, 400B.

[0102] 23 and 24 are perspective views showing an end portion of the first shatterproof part 400. As shown in Fig. 23 and 24, the ends of the first fixing part 410 and the first shielding part 420 of the first shatterproof part 400 may be cut out, and the ends of the first shielding parts 420 of adjacent first shatterproof parts 400 may be butted against each other. This makes it possible to narrow the gap between adjacent first shatterproof parts 400, and further suppresses scattering of glass fragments, resin fragments, metal fragments, etc.

[0103] In the first embodiment, the first shatterproof section 400 has an L-shape, and is disposed so that the joint 425 (the bent portion of the L-shape) faces the outer periphery of the cover 200 (i.e., the side panel 320 side of the housing 300). The first shatterproof section 400 having an L-shape may be disposed so that the joint 425 faces the side surface 136a of the display unit 100 (for example, FIG. 10).

[0104] In the first and second embodiments, the end 422 of the first shielding portion 420 is located near the bottom surface 132a of the display unit 100 (the bottom surface 132a of the chassis 132). The position of the end 422 of the first shielding portion 420 (the height of the end 422 of the first shielding portion 420 from the cover 200) is arbitrary. For example, the end 422 of the first shielding portion 420 may protrude in the rear direction from a plane including the bottom surface 132a of the display unit 100. The end 422 of the first shielding portion 420 may be located between the bottom surface 132a of the display unit 100 and the bottom plate 310 of the housing 300.

[0105] 25, the first shielding portion 420 of the first shatterproof portion 400 may extend to the bottom surface 132a of the display unit 100. This makes it possible to prevent the gap between the first shatterproof portion 400 and the display unit 100 from widening even if the cover 200 is significantly deformed. In particular, when the display unit 100 is formed of a thin display panel such as an organic EL display panel, extending the first shielding portion 420 to the bottom surface 132a of the display unit 100 can further prevent glass fragments, resin fragments, metal fragments, etc. from scattering inside the vehicle.

[0106] 26, a single frame-shaped first shatterproof section 400 may surround one display unit 100. This can further prevent glass fragments, metal fragments, etc. from flying into the air.

[0107] 27, a single frame-shaped first shatterproof section 400 may surround multiple display units 100 in a frame shape, thereby making it possible to further prevent glass fragments, metal fragments, and the like from flying into the air.

[0108] The first shielding portion 420 in the first and sixth embodiments may abut against the display unit 100 (side surface 136a) like the first shielding portion 420 in the second embodiment. The first shielding portion 420 in the fourth embodiment may abut against the inner side surface 320a of the housing 300.

[0109] Furthermore, the first shatterproof unit 400 of the fourth embodiment may be made of metal, rubber, or the like having elasticity (springiness), similarly to the first shatterproof unit 400 of the second embodiment. In this case, the first shielding unit 420 of the first shatterproof unit 400 may come into contact with the inner side surface 320a of the housing 300 and press against the inner side surface 320a.

[0110] In this embodiment, the first shielding portion 420 of the first shatterproof portion 400 is inclined at an acute angle with respect to the back direction of the display unit 100. Since the cover 200 in this embodiment is flat, this can also be said to be inclined at an acute angle with respect to the normal line of the main surface 200a of the cover 200 on the display unit 100 side.

[0111] 28, the first fixing portion 410 of the first shatterproof portion 400 may be located between the cover 200 and the display unit 100. This makes it possible to narrow the gap between the display unit 100 and the side plate 320 of the housing 300.

[0112] The first fixing portion 410 of the first shatterproof portion 400 may be attached to the main surface 200a of the cover 200 via an elastic body 510 as shown in FIG. 29. This can prevent the first shatterproof portion 400 from falling off the cover 200 when the display device 10 is damaged. The elastic body 510 is made of rubber, a sponge-like material, or the like. In the example shown in FIG. 29, the elastic body 510 is adhered to the main surface 200a of the cover 200 by an adhesive member 512, and the first fixing portion 410 is adhered to the elastic body 510 by an adhesive member 514. The second fixing portion 442 of the second shatterproof portion 440 may also be attached to the main surface 200a of the cover 200 via the elastic body 510, similar to the first fixing portion 410 of the first shatterproof portion 400.

[0113] The attachment of the first fixing portion 410 of the first shatterproof portion 400 and the second fixing portion 442 of the second shatterproof portion 440 is not limited to adhesion. For example, the first fixing portion 410 of the first shatterproof portion 400 may be attached to the main surface 200a of the cover 200 by screwing.

[0114] In the embodiment, the first shatterproof part 400 has an L-shape in which the first shielding part 420 is inclined at an acute angle with respect to the rear direction of the display unit 100 when viewed in cross section, as shown in Fig. 30. The first shatterproof part 400 may have a T-shape in which the first shielding part 420 is inclined at an acute angle with respect to the rear direction of the display unit 100 when viewed in cross section. This makes it difficult for the first shatterproof part 400 to fall off the cover 200. The second shatterproof part 440 may also have a T-shape like the first shatterproof part 400.

[0115] In the manufacturing method of the display device 10 in the second embodiment, after the first shatterproof part 400 is attached to the main surface 200a of the cover 200, the display unit 100 is provided on the main surface 200a of the cover 200. As shown in FIG. 31, the manufacturing method of the display device 10 in the second embodiment may include a step of providing the display unit 100 on the main surface 200a of the cover 200 (step S210), a step of attaching the first shatterproof part 400 to the cover 200 (step S220), and a step of storing the display unit 100 in the housing 300 and attaching the cover 200 to the housing 300 (step S130). In step S210, the display unit 100 having the adhesive 204 applied to the display surface 110a is provided on the main surface 200a of the cover 200. Then, the adhesive 204 is cured to bond the display unit 100 and the cover 200 together. In step S220, the first shatterproof part 400 is attached to the main surface 200a of the cover 200 with an adhesive member while the first shielding part 420 of the first shatterproof part 400 is pressed against the side surface 136a of the display unit 100. Step S130 is the same as in embodiment 2. In this manner, the display device 10 of embodiment 2 can be manufactured.

[0116] In the embodiment, the cover 200 is attached to a side panel 320 of the housing 300. The cover 200 does not have to be attached to the housing 300. The cover 200 may be attached to an instrument panel 600, for example.

[0117] In the first to sixth embodiments, the cover 200 is flat. The cover 200 may be curved concavely toward the +Z direction (passenger side) as shown in Fig. 32. The cover 200 may also be curved convexly toward the +Z direction (passenger side).

[0118] The second shatterproof part 440 may come into contact with the side surface 136a of the display unit 100, similar to the first shatterproof part 400. The second shatterproof part 440 may also press against the side surface 136a of the display unit 100.

[0119] In the sixth embodiment, the display device 10 has two second shatterproof parts 440. The display device 10 may have one second shatterproof part 440 as shown in FIG. 33. In the example shown in FIG. 33, the second shatterproof part 440 has one second fixing part 442 and two second shielding parts 444. The two second shielding parts 444 are formed in a V shape. The second shielding part 444 located on the -X side is inclined at an acute angle toward the side of the side surface 136a of the display unit 100 located on the -X side with respect to the rear direction of the display unit 100 located on the -X side. In addition, the second shielding part 444 located on the +X side is inclined at an acute angle toward the side of the side surface 136a of the display unit 100 located on the +X side with respect to the rear direction of the display unit 100 located on the +X side. In this modified example, the distance between the two display units 100 can be narrowed.

[0120] The first shatterproof unit 400 and the second shatterproof unit 440 may be formed integrally. The first shatterproof unit 400 and the second shatterproof unit 440 formed integrally may surround the display unit 100 in a plan view. For example, as shown in FIG. 34, a shatterproof unit 800 obtained by integrating the first shatterproof unit 400 and the second shatterproof unit 440 may be formed in a U-shape and surround one of the display units 100. In FIG. 34, the first shatterproof unit 400 and the shatterproof unit 800 formed in a U-shape surround one of the display units 100 over the entire periphery of the display unit 100.
