Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority from Japanese Patent Application No. 2023-151183 filed on September 19, 2023 and Japanese Patent Application No. 2024-090215 filed on June 3, 2024, the entire disclosures of which are incorporated herein by reference. Technical Field

[0003] The present invention generally relates to a display device and a method for manufacturing a display device. Background Art

[0004] In order to enhance the safety of occupants (crew members and passengers, etc.) on vehicles and trains, etc., it is necessary to reduce the damage to occupants caused by display devices equipped in vehicles and trains, etc. For example, the European vehicle standard (ECE-R21: United Nations Economic Commission for Europe (UN / ECE) - Regulation No. 21) applies to the interior components of vehicles, including display devices. ECE-R21 requires a high level of safety for the interior components of vehicles to protect passengers.

[0005] As a vehicle-mounted display device, a display device having a high-strength cover glass is known. A housing that can prevent the cover glass from scattering is also known. For example, unexamined Japanese Patent Application Publication No. 2017-026694 discloses a display device housing, which includes: a housing body having side walls opposite to each other; and a display device holder that is fixed to each of the side walls and holds a display device having a display surface to which the cover glass is attached. In unexamined Japanese Patent Application Publication No. 2017-026694, when an impact force that may cause the cover glass to break is applied to the cover glass, the display device holder falls off from the housing body before the cover glass breaks.

[0006] In the unexamined Japanese patent application publication No. 2017-026694, the detachment of the display device holder from the housing body suppresses the breakage and scattering of the cover glass. However, such detachment of the display device and the display device holder from the housing body may cause fragments of components of the display device to scatter into the vehicle from the display device holder or the gap between the display device and the housing body.

[0007] The present disclosure is made in view of the above circumstances, and an object of the present disclosure is to provide a display device with high user safety and a method for manufacturing the display device. Summary of the invention

[0008] In order to achieve the above object, a display device according to a first aspect of the present disclosure includes:

[0009] at least one display unit;

[0010] a cover provided on a display surface side of at least one display unit,

[0011] a housing accommodating at least one display unit; and

[0012] a first anti-scattering component, which is disposed on the cover and extends between the display unit and the inner surface of the housing, wherein

[0013] The first scattering prevention member is inclined at an acute angle with respect to a rear direction of the display unit.

[0014] A method for manufacturing a display device according to a second aspect of the present disclosure includes:

[0015] a first step of attaching an anti-scatter component to a major surface of the cover;

[0016] A second step of providing a display unit on the main surface of the cover to which the anti-scattering member is attached, wherein

[0017] The scatter prevention member extends in a rear direction of the display unit and is inclined toward the display unit side relative to the rear direction of the display device, and

[0018] In the second step, the display unit is provided on the main surface of the cover, wherein the scatter prevention member is pressed toward a side opposite to the region where the display unit is provided.

[0019] A method for manufacturing a display device according to a third aspect of the present disclosure includes:

[0020] A first step of providing a display unit on a main surface of the cover; and

[0021] A second step of attaching an anti-scattering member to a cover equipped with the display unit, the anti-scattering member extending in a rear direction of the display unit and inclined toward a display unit side with respect to the rear direction of the display unit.

[0022] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the disclosure.

[0023] According to the present disclosure, the first anti-scattering component is inclined at an acute angle relative to the rear direction of the display unit, and therefore, the scattering of components constituting the display unit can be suppressed. Therefore, the possibility of serious damage to the user due to scattered materials is reduced, and the safety of the display device for the user can be enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] A display device according to various embodiments is described below with reference to the accompanying drawings.

[0059] Example 1

[0060] refer to Figures 1 to 5 The display device 10 according to the present embodiment is described. The display device 10 is installed in a vehicle, an airplane, a home appliance, a piece of furniture, etc. In the present embodiment and the following embodiments, an example in which the display device 10 is installed in a vehicle is described. The passenger of the vehicle corresponds to a user (observer).

[0061] like Figure 1 As shown, the display device 10 is disposed in an opening 610 of an instrument panel 600 of a vehicle. In one example, the instrument panel 600 is formed of resin. For ease of understanding, Figure 1 The longitudinal direction (right direction on the paper) of the display device 10 in the paper is described as the +X direction, the lateral direction (back direction of the paper) is described as the +Y direction, and the direction perpendicular to the +X and +Y directions (upward direction of the paper, passenger direction) is described as the +Z direction. The +Z direction and the direction parallel to the +Z direction are defined as the front direction of the display unit 100 described later, and the -Z direction and the direction parallel to the -Z direction are defined as the rear direction of the display unit 100. For ease of understanding, Figure 1 The hatching of the chassis 132 and the frame 136 etc. is omitted in the figure. In the subsequent figures, the hatching may also be omitted.

[0062] The display device 10 includes a display unit 100, a cover 200, a housing 300, and a first anti-scattering member 400. The display unit 100 displays characters and images, etc. The cover 200 protects the display unit 100. The housing 300 accommodates the display unit 100. The first anti-scattering member 400 suppresses scattering of glass fragments, resin fragments, metal fragments, etc. caused by damage to the display unit 100.

[0063] like Figure 1 As shown, the display unit 100 of the display device 10 includes a liquid crystal display panel 110 , a backlight 120 , and a unit housing 130 .

[0064] In one example, the liquid crystal display panel 110 of the display unit 100 is implemented as a known transmissive horizontal electric field type liquid crystal display panel. The liquid crystal display panel 110 is an active matrix driven by a thin film transistor (TFT). The liquid crystal display panel 110 displays characters, images, etc. by modulating the light from the backlight 120. The liquid crystal display panel 110 includes a display area 111 and a periphery 112. The display area 111 is an area where pixels are arranged in a matrix and characters, images, etc. can be displayed. The periphery 112 is an area where wiring and drive circuits, etc. are set.

[0065] like Figure 2 As shown, the liquid crystal display panel 110 includes a TFT substrate 114, an opposing substrate 115, a liquid crystal 116, a first polarizing plate 117, and a second polarizing plate 118. The TFT substrate 114 and the opposing substrate 115 sandwich the liquid crystal 116. The first polarizing plate 117 is provided on the TFT substrate 114. The second polarizing plate 118 is provided on the opposing substrate 115.

[0066] In one example, the TFT substrate 114 is implemented as a glass substrate. The TFT substrate 114 is positioned at the -Z side. A TFT for selecting pixels, a common electrode, a pixel electrode, a drive circuit, and an alignment film for aligning the liquid crystal 116 are provided on the main surface 114a on the liquid crystal 116 side of the TFT substrate 114 (all not shown in the drawings). The first polarizing plate 117 is provided on the main surface 114b on the side opposite to the main surface 114a of the TFT substrate 114.

[0067] The counter substrate 115 is positioned at the +Z side and is opposite to the TFT substrate 114. The counter substrate 115 is adhered to the TFT substrate 114 by a sealing material 119. In one example, the counter substrate 115 is implemented as a glass substrate. A color filter, a black matrix, and an alignment film for aligning the liquid crystal 116 are provided on the main surface 115a on the liquid crystal 116 side of the counter substrate 115 (all not shown in the drawings). The second polarizing plate 118 is provided on the main surface 115b on the side opposite to the main surface 115a of the counter substrate 115.

[0068] In one example, the TFT substrate 114 and the counter substrate 115 are formed of non-alkali glass. Non-alkali glass does not contain alkaline components such as sodium and potassium, which can suppress contamination of the liquid crystal 116 by the alkaline components and deterioration of the display quality of the liquid crystal display panel 110.

[0069] The liquid crystal 116 is sandwiched between the TFT substrate 114 and the counter substrate 115. In one example, the liquid crystal 116 is implemented as a positive 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 the alignment film. In addition, when a voltage is applied, the liquid crystal 116 rotates in a plane parallel to the main surface 114a of the TFT substrate 114.

[0070] The first polarizing plate 117 is provided on the main surface 114b of the TFT substrate 114. The second polarizing plate 118 is provided on the main surface 115b of the counter substrate 115. One of the transmission axes of the first polarizing plate 117 and the second polarizing plate 118 is arranged parallel to the initial alignment direction of the liquid crystal 116, and the transmission axis of the first polarizing plate 117 is orthogonal to the transmission axis of the second polarizing plate 118. In the present embodiment, the main surface 118a on the +Z side of the second polarizing plate 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).

[0071] like Figure 1 As shown, the backlight 120 of the display unit 100 is arranged on the rear side (-Z side) of the liquid crystal display panel 110. The backlight 120 is the light source of the liquid crystal display panel 110. The backlight 120 emits white light on the liquid crystal display panel 110. The backlight 120 includes a white light emitting diode (LED) element, a reflective sheet, a diffuser, a light guide plate, a lighting circuit, etc. (all not shown in the drawings). In one example, the light guide plate is formed of a light-transmitting acrylic resin (polymethyl methacrylate (PMMA)).

[0072] The unit housing 130 of the display unit 100 accommodates the liquid crystal display panel 110 and the backlight 120. The unit housing 130 includes a chassis 132 and a bezel 136. However, a configuration is possible in which the bezel 136 is not provided on the unit housing 130.

[0073] The chassis 132 has a box-like shape. The chassis 132 is formed of resin or metal. The chassis 132 accommodates the liquid crystal display panel 110 and the backlight 120 inside thereof.

[0074] The frame 136 has a box-like shape. The frame 136 has an opening 138 on its bottom 137. In one example, the frame 136 is formed of metal. The frame 136 covers the chassis 132 with the bottom 137 facing the +Z side, and protects the periphery 112 of the liquid crystal display panel 110. The display area 111 of the liquid crystal display panel 110 is exposed through the opening 138.

[0075] The cover 200 of the display device 10 is provided on the display surface 110a side (+Z side) of the display unit 100, and protects the display unit 100. The cover 200 is formed into a flat plate, and is formed of a light-transmitting resin, glass, or the like. In the case where the cover 200 is formed of glass, the cover 200 is typically formed of tempered glass, but the cover 200 may also be formed of 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 Figure 1 As shown, in a cross-sectional view, the cover 200 extends outward from the outer shape of the display unit 100. In the present embodiment, the cover 200 is attached to a side plate 320 of a housing 300 described later by an adhesive member 202. The space between the cover 200 and the liquid crystal display panel 110 is filled with a light-transmitting adhesive 204 (e.g., an optical clear adhesive (OCA)).

[0076] The housing 300 of the display device 10 has a box-like shape and accommodates the display unit 100. In one example, the housing 300 is formed of metal. The housing 300 includes a bottom plate 310 and a side plate 320. In the present embodiment, the housing 300 supports the display unit 100 through a support member 312 of the bottom plate 310. The side plate 320 is adhered to the inner wall surface 610a of the opening 610 of the instrument panel 600 by an adhesive not shown. Thus, the display device 10 is fixed to the opening 610 of the instrument panel 600.

[0077] like Figure 1 , Figure 3 and Figure 4 As shown, the four first anti-scattering members 400 of the display device 10 are provided on the main surface 200a of the cover 200 on the display unit 100 side thereof. When viewed in a plan view, the four first anti-scattering members 400 extend along the long side (X direction) or the short side (Y direction) of the display unit 100 and surround the display unit 100 in a frame-like manner, as shown in FIG. Figure 3 As shown. Figure 3 and Figure 4 In the drawings, the display unit 100 is simplified and illustrated for easy understanding. In subsequent drawings, the display unit 100 may be simplified.

[0078] The first anti-scattering member 400 includes a first fixing portion 410 and a first shielding portion 420. The first fixing portion 410 is attached to the main surface 200a of the cover 200 via an adhesive member not shown. Figure 1 and Figure 4As shown, the first fixing portion 410 is attached to the main surface 200a of the cover 200 at a portion located outward from the side surface 136a of the display unit 100. The first fixing portion 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.

[0079] like Figure 1 As shown, the first shielding portion 420 extends from the first fixing portion 410 between the side surface 136a of the display unit 100 (the side surface 136a of the frame 136) and the inner surface 320a of the side plate 320 of the housing 300. Figure 4 As shown, the first shielding portion 420 is inclined at an acute angle relative to the rear direction of the display unit 100 (a line extending parallel to the -Z direction and passing through the joint 425 between the first fixing portion 410 and the first shielding portion 420) toward the side surface 136a of the display unit 100. That is, the angle between the first shielding portion 420 and the rear direction of the display unit 100 is an acute angle that opens to the rear direction (-Z direction) of the display unit 100. When viewed in cross section, the first anti-scattering component 400 can be considered to have an L-shape, in which the first shielding portion 420 is inclined at an acute angle relative to the rear direction of the display unit 100.

[0080] In one example, the first anti-scattering component 400 is formed of synthetic resin, metal, rubber, etc. In this embodiment, the first anti-scattering component 400 is formed of synthetic resin. Figure 4 As shown, the first scattering prevention member 400 is provided with an engaging portion 425 (L-shaped bend) facing the outer periphery of the cover 200 .

[0081] In the present embodiment, when the display device 10 is damaged due to an impact applied to the display device 10 (cover 200) from the passenger side (+Z side), because the first shielding portion 420 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, the first shielding portion 420 of the first anti-scattering member 400 closes the gap between the cover 200 and the display unit 100 (frame 136), as shown in FIG. Figure 5 This can suppress the fragments of glass, resin, metal, etc. from being scattered into the vehicle through between the cover 200 and the display unit 100.

[0082] In addition, the first shielding portion 420 of the first anti-scattering member 400 is inclined at an acute angle toward the side surface 136a side of the display unit 100 relative to the rear direction of the display unit 100, and therefore, the gap between the side surface 136a of the display unit 100 and the first shielding portion 420 can be narrowed. In addition, even if a portion of the cover 200 to which the first anti-scattering member 400 (first fixing portion 410) is attached is deformed, the expansion of the gap between the side surface 136a of the display unit 100 and the first shielding portion 420 due to the displacement of the first shielding portion 420 toward the inner surface 320a of the housing 300 can be suppressed because the first shielding portion 420 is previously placed to be inclined at an acute angle toward the side surface 136a of the display unit 100 relative to the rear direction of the display unit 100. This can suppress the scattering of fragments of glass, resin, metal, etc. from between the first shielding portion 420 and the display unit 100. That is, the first anti-scattering component 400 is particularly effective in suppressing the scattering of glass fragments of the TFT substrate 114 and the opposing substrate 115, resin and metal fragments of the light guide plate, chassis 132, frame 136, etc. caused by the display unit 100 due to damage to the display device 10.

[0083] As above, the first shielding portion 420 of the first anti-scattering member 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 136b of the display unit 100 relative to the rear direction of the display unit 100, and therefore, it is possible to suppress the fragments of glass, resin, metal, etc. from being scattered into the vehicle due to damage. This can enhance the safety of the display device 10 for the user.

[0084] Example 2

[0085] In Embodiment 1, the first anti-scattering component 400 is formed of a synthetic resin. The first anti-scattering component 400 may be a metal, rubber, or the like having elasticity (spring properties). Except for the configuration of the first anti-scattering component 400, the configuration of the display device 10 of this embodiment is the same as that of the display device 10 of Embodiment 1. Here, the first anti-scattering component 400 of this embodiment is described.

[0086] The first anti-scattering component 400 of this embodiment is formed of a metal thin plate having elasticity (spring property). The first anti-scattering component 400 of this embodiment has elastic restoring force in the direction in which the first fixing part 410 and the first shielding part 420 are closed. Figure 6As shown, the first shielding portion 420 of the first anti-scattering component 400 contacts the display unit 100 (side surface 136a) and presses the display unit 100 in the center direction of the display unit 100. The other configurations of the first anti-scattering component 400 of this embodiment are the same as those of the first anti-scattering component 400 of Embodiment 1. Figure 6 , the first shielding portion 420 is shown to be flat, but due to elasticity, the first shielding portion 420 may be bent.

[0087] In the present embodiment, the first shielding portion 420 of the first anti-scattering member 400 is pressed against the display unit 100, and therefore, even if the display device 10 is damaged, the first shielding portion 420 can maintain contact with the display unit 100, as shown in FIG. Figure 7 Therefore, a gap between the display unit 100 and the first shielding portion 420 is less likely to occur, and scattering of fragments of glass, metal, etc. into the vehicle due to damage can be suppressed.

[0088] Next, refer to Figure 8 and Fig. 9 A method of manufacturing the display device 10 of the present embodiment is described. Figure 8 1 is a flowchart showing a method for manufacturing the display device 10. The method for manufacturing the display device 10 includes a step of attaching the first anti-scattering member 400 to the main surface 200a of the cover 200 (step S110), a step of arranging the display unit 100 on the main surface 200a of the cover 200 to which the first anti-scattering member 400 is attached (step S120), and a step of accommodating the display unit 100 in the housing 300 and attaching the cover 200 to the housing 300 (step S130).

[0089] In step S110, the first anti-scattering member 400 formed of metal having elasticity is attached to the main surface 200a of the cover 200. Specifically, the first fixing portion 410 of the first anti-scattering member 400 is adhered to the main surface 200a of the cover 200 by an adhesive member (eg, double-sided tape).

[0090] In step S120, Fig. 9As shown, the first shielding portion 420 of the first anti-scattering member 400 is pressed toward the side opposite to the area where the display unit 100 is set using a jig not shown to ensure a space for the display unit 100, and the display unit 100 to which the adhesive 204 is applied on the display surface 110a is set on the main surface 200a of the cover 200 while the first shielding portion 420 is pressed. Then, the adhesive 204 is cured to adhere the display unit 100 to the cover 200. After the adhesive 204 is cured, the pressing of the first shielding portion 420 is released, and the first shielding portion 420 is brought into contact with the display unit 100. This can achieve a state in which the first shielding portion 420 of the first anti-scattering member 400 is pressed on the display unit 100.

[0091] In step S130, the display unit 100 attached to the cover 200 is accommodated in the housing 300, and the cover 200 is attached to the side plate 320 of the housing 300 through the adhesive member 202. The display device 10 may be manufactured through the above-described process.

[0092] As above, the first shielding part 420 of the first anti-scattering member 400 presses the display unit 100, and therefore, even if the display device 10 is damaged, the first shielding part 420 can maintain contact with the display unit 100, and the fragments of glass, resin, metal, etc. that are scattered into the vehicle due to the damage can be further suppressed. This can enhance the safety of the display device 10 for the user.

[0093] Example 3

[0094] The first fixing portion 410 of the first anti-scattering component 400 may be positioned between the cover 200 and the side plate 320 of the housing 300. The configuration of the display device 10 of the present embodiment is the same as that of the display device 10 of Embodiment 1 except for the configuration and arrangement of the first anti-scattering component 400. Here, the first anti-scattering component 400 of the present embodiment is described.

[0095] The first anti-scattering component 400 of this embodiment includes a first fixing portion 410 and a first shielding portion 420, similar to the first anti-scattering component 400 of embodiment 1. The first anti-scattering component 400 of this embodiment is formed of synthetic resin, similar to the first anti-scattering component 400 of embodiment 1.

[0096] In this embodiment, the first fixing portion 410 of the first anti-scattering component 400 is positioned between the cover 200 and the side plate 320 of the housing 300. Fig.10Specifically, the first fixing portion 410 is positioned between the cover 200 and the top surface 320b of the side plate 320 of the housing 300. The first fixing portion 410 is adhered to the top surface 320b of the side plate 320 of the housing 300 by the first adhesive member 502, and is adhered to the main surface 200a of the cover 200 by the second adhesive member 504.

[0097] In one example, the first adhesive member 502 and the second adhesive member 504 are double-sided tapes. In this embodiment, the adhesive force of the first fixing portion 410 to the main surface 200a of the cover 200 by the second adhesive member 504 is greater than the adhesive force of the first fixing portion 410 to the top surface 320b of the side plate 320 of the housing 300 by the first adhesive member 502. In other words, the adhesive force of the first fixing portion 410 to the main surface 200a of the cover 200 by the second adhesive member 504 is stronger than the adhesive force of the first fixing portion 410 to the top surface 320b of the side plate 320 of the housing 300 by the first adhesive member 502. This can maintain the state in which the first anti-scattering component 400 is attached to the main surface 200a of the cover 200 when the display device 10 is damaged.

[0098] The first shielding portion 420 of the first anti-scattering member 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, similar to the first shielding portion 420 of Embodiment 1. 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.

[0099] The other structures of the first scattering prevention component 400 of the present embodiment are the same as those of the first scattering prevention component 400 of the first embodiment.

[0100] like Fig.11 As shown, when the display device 10 is damaged due to an impact from the passenger side (+Z side), the first anti-scattering member 400 remains on the main surface 200a of the cover 200, and the first shielding portion 420 closes the gap between the cover 200 and the housing 300 (side plate 320) because the adhesion force of adhering the first fixing portion 410 to the main surface 200a of the cover 200 is greater than the adhesion force of adhering the first fixing portion 410 to the top surface 320b of the side plate 320 of the housing 300. This can suppress fragments of glass, resin, metal, etc. from being scattered into the vehicle through between the cover 200 and the housing 300.

[0101] In this embodiment, the first shielding portion 420 closes the gap between the cover 200 and the housing 300 (side panel 320), and therefore, even if fragments of glass, resin, metal, etc. caused inside the display device 10 due to damage to the display device 10 appear on the rear side of the display unit 100, these fragments can be suppressed from being scattered into the vehicle.

[0102] As described above, the display device 10 of the present embodiment can suppress the fragments of glass, resin, metal, etc. from being scattered into the vehicle due to damage, and enhance the safety of the user. In addition, because the first fixing portion 410 of the first anti-scattering component 400 is positioned above the side plate 320 of the housing 300, less space is required to equip the first anti-scattering component 400, and the spacing between the display unit 100 and the side plate 320 of the housing 300 can be narrowed.

[0103] Example 4

[0104] In Embodiments 1 to 3, the first shielding portion 420 of the first anti-scattering component 400 is inclined at an acute angle toward the side surface 136a side of the display unit 100 relative to the rear direction of the display unit 100. The first shielding portion 420 may be inclined at an acute angle toward the inner surface 320a of the housing 300 relative to the rear direction of the display unit 100. The configuration of the display device 10 of the present embodiment is the same as that of the display device 10 of Embodiment 1 except for the configuration of the first anti-scattering component 400. The first anti-scattering component 400 of the present embodiment is described.

[0105] The first anti-scattering component 400 of this embodiment includes a first fixing portion 410 and a first shielding portion 420, similar to the first anti-scattering component 400 of Embodiment 1. The first anti-scattering component 400 of this embodiment is formed of a synthetic resin and is disposed on the main surface 200a of the cover 200, similar to the first anti-scattering component 400 of Embodiment 1.

[0106] The first fixing portion 410 is attached to the main surface 200a of the cover 200 via an adhesive member. Fig.12 As shown, the first shielding portion 420 extends from the first fixing portion 410 to 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 side of the housing 300 relative to the rear direction of the display unit 100.

[0107] The other structures of the first scattering prevention component 400 of the present embodiment are the same as those of the first scattering prevention component 400 of the first embodiment.

[0108] like Fig.13As shown, when the display device 10 is damaged due to an impact from the passenger side (+Z side), the first shielding portion 420 inclined at an acute angle toward the inner surface 320a side of the housing 300 relative to the rear direction of the display unit 100 closes the gap between the cover 200 and the housing 300 (side plate 320). This can suppress fragments of glass, metal, etc. from being scattered into the vehicle through between the cover 200 and the housing 300.

[0109] As described above, the display device 10 of the present embodiment can suppress fragments of glass, metal, etc. from being scattered into the vehicle due to damage, and enhance the safety of the user.

[0110] Example 5

[0111] In Embodiment 1, the housing 300 accommodates the display unit 100. The housing 300 may accommodate components other than the display unit 100. Among the plurality of first anti-scattering members 400, the first shielding portion 420 may have an end portion 422 whose height (position) from the cover 200 is different.

[0112] The display device 10 of the present embodiment includes a display unit 100, a cover 200, a housing 300, three first scattering prevention components 400A, a single first scattering prevention component 400B, and an imager 700. The configurations of the display unit 100 and the cover 200 of the present embodiment are the same as those in Embodiment 1, and therefore, the imager 700, the housing 300, the first scattering prevention component 400A, and the first scattering prevention component 400B are described here.

[0113] The imager 700 captures images of passengers, the interior of the vehicle, etc. The imager 700 is housed in the housing 300, such as Fig.14 The imager 700 has a light source 710 and an imaging element 720 . The light source 710 and the imaging element 720 are disposed in an imager housing 730 .

[0114] The light source 710 is a white light LED element, an infrared LED element, etc. The imaging element 720 is a charge coupled device (CCD) image sensor, an infrared image sensor, etc.

[0115] The housing 300 of the present embodiment accommodates the display unit 100 and the imager 700. The display unit 100 and the imager 700 are arranged side by side in the housing 300 along the X direction. Specifically, the display unit 100 is positioned on the +X side, and the imager 700 is positioned on the -X side. Therefore, when viewed in a cross section on the XZ plane, as shown in FIG. Fig.14 As shown, the center line DZ bisecting the display unit 100 is offset in the +X direction relative to the center line CZ bisecting the cover 200. The other configurations of the housing 300 of this embodiment are the same as those of the housing 300 of the first embodiment.

[0116] The first anti-scattering member 400A and the first anti-scattering member 400B suppress the scattering of fragments of glass, resin, metal, etc. caused by damage to the display unit 100, similar to the first anti-scattering member 400 of Embodiments 1 to 4. The first anti-scattering member 400A and the first anti-scattering member 400B are formed of synthetic resin, similar to the first anti-scattering member 400 of Embodiment 1. Fig.14 and Fig.15 As shown, each of the three first anti-scattering parts 400A and the single first anti-scattering part 400B is provided on the main surface 200 a of the cover 200 .

[0117] When viewed in plan view, Fig.15 As shown, two first anti-scattering components 400A extending along the long side (X direction) of the display unit 100 sandwich the display unit 100. One of the first anti-scattering components 400A extending along the short side (Y direction) of the display unit 100 is disposed at the +X side of the display unit 100. A single first anti-scattering component 400B extending along the short side (Y direction) of the display unit 100 is disposed at the -X side of the imager 700 and the display unit 100. The three first anti-scattering components 400A and the single first anti-scattering component 400B surround the display unit 100 and the imager 700.

[0118] The first anti-scattering component 400A and the first anti-scattering component 400B each include a first fixing portion 410 and a first shielding portion 420, similar to the first anti-scattering component 400 of Embodiments 1 to 4. The first fixing portion 410 is attached to the main surface 200a of the cover 200 via an adhesive member. Fig.14 As shown, the first shielding portion 420 of the first anti-scattering component 400A extends from the first fixing portion 410 to 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 portion 420 of the first anti-scattering component 400A is inclined at an acute angle toward the side surface 136a of the display unit 100 relative to the rear direction of the display unit 100, similar to the first shielding portion 420 of Embodiments 1 to 3. The first shielding portion 420 of the first anti-scattering component 400B extends from the first fixing portion 410 to 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 anti-scattering component 400B and the side surface 136a of the display unit 200 sandwich the imager 700. The first shielding portion 420 of the first scattering prevention member 400B is inclined at an acute angle toward the inner surface 320 a side of the housing 300 with respect to the rear surface of the display unit 100 , similar to the first shielding portion 420 of Embodiment 4.

[0119] In the present embodiment, the height H2 of the end portion 422 (the end portion not connected to the fixed portion) of the first shielding portion 420 of the first anti-scattering member 400B from the cover 200 is different from the height H1 of the end portion 422 of the first shielding portion 420 of the first anti-scattering member 400A from the cover 200. Specifically, the height H2 of the end portion 422 of the first shielding portion 420 of the first anti-scattering member 400B from the cover 200 is greater than the height H1 of the end portion 422 of the first shielding portion 420 of the first anti-scattering member 400A from the cover 200. In other words, the height H2 of the end portion 422 of the first shielding portion 420 of the first anti-scattering member 400B from the cover 200 is higher than the height H1 of the end portion 422 of the first shielding portion 420 of the first anti-scattering member 400A from the cover 200. The height of the end portion 422 from the cover 200 is also indicated by the position of the display unit 100 in the rear direction relative to the cover 200 of the end portion 422.

[0120] In the present embodiment, the center line DZ bisecting the display unit 100 is offset in the +X direction relative to the center line CZ bisecting the cover 200, and therefore, when the display device 10 is damaged due to an impact applied to the display unit 100 through the cover 200, the gap D2 between the cover 200 and the side plate 320 of the housing 300 on the -X side becomes wider than the gap D1 between the cover 200 and the side plate 320 of the housing 300 on the +X side, as shown in FIG. Fig.16 The height H2 of the end portion 422 of the first shielding portion 420 of the first anti-scattering member 400B provided on the -X side of the display unit 100 and the imager 700 is greater than the height H1 of the end portion 422 of the first shielding portion 420 of the first anti-scattering member 400A. Therefore, the first shielding portion 420 of the first anti-scattering member 400B can easily close the wide gap D2 and suppress fragments of glass, metal, etc. from being scattered into the vehicle.

[0121] As described above, the display device 10 of the present embodiment can suppress fragments of glass, metal, etc. from being scattered into the vehicle due to damage, and enhance the safety of the user.

[0122] Example 6

[0123] In Embodiment 1, the display device 10 includes a single display unit 100. The display device 10 may include a plurality of display units 100. The display device 10 may include a second anti-scattering member 440 extending between two juxtaposed display units 100.

[0124] The display device 10 of the present embodiment includes two display units 100, a cover 200, a housing 300, four first anti-scattering parts 400, and two second anti-scattering parts 440. The configuration of the cover 200 of the present embodiment is the same as that in Embodiment 1, and therefore, the display unit 100, the housing 300, the first anti-scattering parts 400, and the second anti-scattering parts 440 are described here.

[0125] In this embodiment, if Fig.17 As shown, two display units 100 are juxtaposed in the X direction and housed in a housing 300. The space between the cover 200 and each of the display units 100 is filled with a light-transmitting adhesive 204. The other configurations of the display unit 100 of this embodiment are the same as those in Embodiment 1.

[0126] The housing 300 of this embodiment accommodates two display units 100. The other configurations of the housing 300 of this embodiment are the same as those of the first embodiment.

[0127] When viewed in plan view, Fig.18 As shown, the two first anti-scattering components 400 of the present embodiment extend in the X direction and sandwich the two display units 100. In addition, the other two first anti-scattering components 400 of the present embodiment extend in the Y direction and sandwich the two display units 100. The four first anti-scattering components 400 of the present embodiment surround the two display units 100 in a frame-like manner. The other configurations of the first anti-scattering components 400 of the present embodiment are the same as those in Embodiment 1.

[0128] The second anti-scattering component 440 suppresses the scattering of fragments of glass, resin, metal, etc. caused by damage to the display unit 100, similar to the first anti-scattering component 400. The second anti-scattering component 440 is provided on the main surface 200a of the cover 200, similar to the first anti-scattering component 400. When viewed in a plan view, the second anti-scattering component 440 is provided between two juxtaposed display units 100. In the present embodiment, two second anti-scattering components 440 extending in the Y direction are arranged side by side in the X direction between the two juxtaposed display units 100.

[0129] The second scattering prevention member 440 is formed of synthetic resin, metal, rubber, etc., similar to the first scattering prevention member 400. The second scattering prevention member 440 includes 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.

[0130] like Fig.17As shown, 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 anti-scattering component 440 positioned on the -X side is inclined at an acute angle relative to the rear direction of the display unit 100 positioned on the -X side toward the side surface 136a of the display unit 100 positioned on the -X side. The second shielding portion 444 of the second anti-scattering component 440 positioned on the +X side is inclined at an acute angle relative to the rear direction of the display unit 100 positioned on the +X side toward the side surface 136a side of the display unit 100 positioned on the +X side.

[0131] In the present embodiment, the first anti-scattering member 400 can suppress fragments of glass, resin, metal, etc. from entering the vehicle through between the cover 200 and the display unit 100, similar to Embodiment 1. When viewed in a plan view, four first anti-scattering members 400 surround the two display units 100 in a frame-like manner. Therefore, even if an impact is applied between the two display units 100, fragments of glass, resin, metal, etc. can be suppressed from being scattered into the vehicle.

[0132] When the display device 10 is damaged, the second shielding portion 444 of the second anti-scattering member 440 extends between the two display units 100, and thus, the second shielding portion 444 closes the gap between the cover 200 and the display unit 100. This can further suppress the fragments of glass, resin, metal, etc. from being scattered into the vehicle through between the cover 200 and the display unit 100.

[0133] In addition, the second shielding portion 444 is inclined at an acute angle toward the side surface 136a side of the display unit 100 with respect to the rear direction of the display unit 100, and thus 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, the second shielding portion 444 is inclined at an acute angle toward the side surface 136a side of the display unit 100 with respect to the rear direction of the display unit 100, and thus, the expansion of the gap between the side surface 136a of the display unit 100 and the second shielding portion 444 can be suppressed. This can suppress fragments of glass, resin, metal, etc. from being scattered from between the second shielding portion 444 and the display unit 100.

[0134] As described above, the display device 10 of the present embodiment can further suppress the scattering of fragments of glass, metal, etc. into the vehicle due to damage and enhance the safety of the user.

[0135] Example 7

[0136] In Embodiment 1, the display unit 100 and the cover 200 have a flat plate shape. The display unit 100 and the cover 200 may be curved.

[0137] The display device 10 of the present embodiment includes a display unit 100, a cover 200, a housing 300, and four first anti-scattering components 400, similar to the display device 10 of Embodiment 1. The configuration of the housing 300 of the present embodiment is the same as that of Embodiment 1, and therefore, the display unit 100, the cover 200, and the first anti-scattering components 400 in the present embodiment are described here.

[0138] like Fig.19 As shown, the display unit 100 and the cover 200 of the present embodiment are curved concavely in the +Z direction (passenger side). The other configurations of the display unit 100 and the cover 200 of the present embodiment are the same as those in the first embodiment.

[0139] The first anti-scattering component 400 of the present embodiment suppresses scattering of fragments of glass, resin, metal, etc. caused by damage to the display unit 100, similar to the first anti-scattering component 400 of Embodiment 1. The first anti-scattering component 400 of the present embodiment includes a first fixing portion 410 and a first shielding portion 420, similar to the first anti-scattering component 400 of Embodiment 1. The first fixing portion 410 of the present embodiment is attached to the main surface 200a of the cover 200 via an adhesive member.

[0140] The first shielding portion 420 of the present embodiment extends from the first fixing portion 410 to between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300, similar to the first shielding portion 420 of Embodiment 1. In addition, when viewed in cross section, the first shielding portion 420 of the present embodiment is inclined in a direction in which the interval S between the first shielding portion 420 and the side surface 136a of the display unit 100 becomes narrower toward the rear direction of the display unit 100 with respect to the side surface 136a of the display unit 100, as shown in FIG. Fig.19 and Fig. 20 shown.

[0141] In the present embodiment, the first shielding portion 420 extends from the first fixing portion 410 to 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, the first shielding portion 420 can close the gap between the cover 200 and the display unit 100, and suppress the fragments of glass, resin, metal, etc. from being scattered into the vehicle. In addition, the first shielding portion 420 is inclined in a direction in which the interval S between the first shielding portion 420 and the side surface 136a of the display unit 100 becomes narrower toward the rear direction of the display unit 100, and therefore, the gap between the side surface 136a of the display unit 100 and the first shielding portion 420 can be narrowed, and the fragments of glass, resin, metal, etc. from being scattered into the vehicle can be further suppressed.

[0142] In the present embodiment, the side surface 136a of the display unit 100 is inclined toward the inner surface 320a side of the housing 300 relative to the rear direction of the display unit 100, but the inclination direction of the side surface 136a of the display unit 100 relative to the rear direction of the display unit 100 can be determined as needed. A configuration is possible in which the side surface 136a of the display unit 100 is not inclined relative to the rear direction of the display unit 100. In the present embodiment, the first shielding portion 420 is in contact with the side surface 136a of the display unit 100. The angle θ between the first shielding portion 420 and the side surface 136a of the display unit 100 is an acute angle opened toward the passenger side (+Z direction), as shown in FIG. Fig. 20 shown.

[0143] Example 8

[0144] In Embodiment 7, the cover 200 of the display unit 100 is curved concavely in the +Z direction (passenger side). The display unit 100 and the cover 200 may be curved convexly in the +Z direction (passenger side).

[0145] The display device 10 of this embodiment includes a display unit 100 , a cover 200 , a housing 300 , and four first anti-scattering members 400 , which is similar to the display device 10 of the first embodiment.

[0146] like Fig.21 As shown, the display unit 100 and the cover 200 of this embodiment are convexly curved in the +Z direction (passenger side). The cover 200 of this embodiment is attached to the inner surface 320a of the housing 300 by an unillustrated adhesive member. The other configurations of the display unit 100 and the cover 200 of this embodiment are the same as those in Embodiment 1.

[0147] The housing 300 of the present embodiment accommodates the display unit 100. The housing 300 of the present embodiment has a box-like shape in which the opening side is wider than the bottom plate 310 as viewed in cross section. In the housing 300 of the present embodiment, the side plate 320 is open toward the outside of the housing 300, and the side plate 320 (inner surface 320a) is inclined toward the outside of the housing 300 relative to the rear direction of the display unit 100.

[0148] The first anti-scattering component 400 of the present embodiment suppresses the scattering of fragments of glass, resin, metal, etc. caused by damage to the display unit 100, similar to the first anti-scattering component 400 of Embodiment 1. The first anti-scattering component 400 of the present embodiment includes a first fixing portion 410 and a first shielding portion 420. The first fixing portion 410 of the present embodiment is attached to the main surface 200a of the cover 200 via an adhesive member.

[0149] The first shielding portion 420 of the present embodiment extends from the first fixing portion 410 to between the side surface 136a of the display unit 100 and the inner surface 320a of the side plate 320 of the housing 300, similar to the first shielding portion 420 of Embodiment 1. When viewed in cross section, the first shielding portion 420 of the present embodiment is inclined in a direction in which the interval T between the first shielding portion 420 and the inner surface 320a becomes narrower toward the rear direction of the display unit 100 with respect to the inner surface 320a of the housing 300, as shown in FIG. Fig.21 and 22 shown.

[0150] In the present embodiment, the first shielding portion 420 extends from the first fixing portion 410 to 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, the first shielding portion 420 can close the gap between the cover 200 and the display unit 100, and suppress the scattering of fragments of glass, resin, metal, etc. into the vehicle. In addition, the first shielding portion 420 is inclined in a direction in which the interval T between the first shielding portion 420 and the inner surface 320a becomes narrower toward the rear direction of the display unit 100, and therefore, the gap between the inner surface 320a and the first shielding portion 420 can be narrowed, and the scattering of fragments of glass, resin, metal, etc. can be further suppressed.

[0151] In the present embodiment, the side plate 320 (inner surface 320a) of the housing 300 is inclined toward the outside of the housing 300 relative to the rear direction of the display unit 100, but the inclination direction of the side plate 320 of the housing 300 relative to the rear direction can be determined as needed. A configuration is possible in which the side plate 320 of the housing 300 is not inclined relative to the rear direction of the display unit 100. Fig. 22 As shown, the angle between the first shielding portion 420 and the inner surface 320a is It is an acute angle that opens toward the passenger side (+Z direction).

[0152] Modified Example

[0153] Although embodiments have been described above, various modifications may be made without departing from the spirit and scope of the present disclosure.

[0154] For example, a configuration is possible in which the display unit 100 includes an organic electro-luminescence (EL) display panel instead of the liquid crystal display panel 110 and the backlight 120. A configuration is possible in which the display unit 100 does not include the unit housing 130.

[0155] The display device 10 may include a touch panel between the cover 200 and the display unit 100. The touch panel is adhered to each of the cover 200 and the liquid crystal display panel 110 of the display unit 100, for example, by a light-transmitting adhesive.

[0156] In the embodiment, the display device 10 includes a plurality of first anti-scattering members 400 , 400A, 400B, but it is sufficient that the display device 10 includes at least one first anti-scattering member 400 , 400A, 400B.

[0157] Fig.23 and Fig.24 4 is a perspective view showing an end portion of the first anti-scattering component 400. Fig.23 and Fig.24 As shown, the end portions of the first fixing portion 410 and the first shielding portion 420 of the first anti-scattering component 400 may be grooved, and the ends of the first shielding portions 420 of adjacent first anti-scattering components 400 may abut against each other. This can narrow the gap between adjacent first anti-scattering components 400 and suppress the scattering of fragments of glass, resin, metal, etc.

[0158] In Embodiment 1, the first anti-scattering member 400 has an L-shape and is provided with a joint portion 425 (L-shaped bend) facing the outer periphery of the cover 200 (i.e., the side plate 320 side of the housing 300). The first anti-scattering member 400 having an L-shape may be provided with a joint portion 425 (e.g., at the side surface 136a side of the display unit 100) facing the side surface 136a side of the display unit 100. Fig.10 middle).

[0159] In Embodiments 1 and 2, the end portion 422 of the first shielding portion 420 is positioned near the bottom surface 132a of the display unit 100 (the bottom surface 132a of the chassis 132). The position of the end portion 422 of the first shielding portion 420 (the height of the end portion 422 of the first shielding portion 420 from the cover 200) can be determined as needed. For example, the end portion 422 of the first shielding portion 420 may protrude in the rearward direction from the plane including the bottom surface 132a of the display unit 100. The end portion 422 of the first shielding portion 420 is positioned between the bottom surface 132a of the display unit 100 and the bottom plate 310 of the housing 300.

[0160] The first shielding portion 420 of the first anti-scattering member 400 may extend to the bottom surface 132a of the display unit 100, such as Fig.25Even if the cover 200 is greatly deformed, this can suppress the widening of the gap between the first anti-scattering member 400 and the display unit 100. In particular, when the display unit 100 is formed of a thin display panel such as an organic EL display panel, by extending the first shielding portion 420 to the bottom surface 132a of the display unit 100, it is possible to further suppress the fragments of glass, resin, metal, etc. from being scattered into the vehicle.

[0161] When viewed in a plan view, the first anti-scattering member 400 having a single frame shape may surround one display unit 100 in a frame-like manner, such as Fig.26 This can prevent the scattering of broken pieces of glass, metal, etc.

[0162] In addition, if Fig. 27 As shown, the first anti-scattering member 400 having a single frame shape can surround the plurality of display units 100 in a frame-like manner. This can suppress the scattering of fragments of glass, metal, etc.

[0163] The first shielding portion 420 of Embodiments 1 and 6 may contact the display unit 100 (side surface 136 a ), similar to the first shielding portion 420 of Embodiment 2. The first shielding portion 420 of Embodiment 4 may contact the inner surface 320 a of the housing 300 .

[0164] The first anti-scattering component 400 of embodiment 4 may be formed of metal, rubber, etc. having elasticity (spring properties), similar to the first anti-scattering component 400 of embodiment 2. In this case, the first shielding portion 420 of the first anti-scattering component 400 may contact and press the inner surface 320a of the housing 300.

[0165] In Embodiments 1 to 6, the first shielding portion 420 of the first scattering prevention member 400 is inclined at an acute angle relative to the rear direction of the display unit 100. The cover 200 of Embodiments 1 to 6 has a flat plate shape, and therefore the first shielding portion 420 of the first scattering prevention member 400 can also be described as being inclined at an acute angle relative to the normal on the display unit 100 side of the main surface 200a of the cover 200.

[0166] The first fixing portion 410 of the first anti-scattering member 400 may be positioned between the cover 200 and the display unit 100, such as Fig.28 This can narrow the distance between the display unit 100 and the side plate 320 of the housing 300 .

[0167] The first fixing portion 410 of the first anti-scattering member 400 may be attached to the main surface 200a of the cover 200 via the elastic body 510, as shown in FIG. Fig.29As shown. This can suppress the first anti-scattering member 400 from falling off from the cover 200 when the display device 10 is damaged. The elastic body 510 is formed of rubber, sponge-like material, etc. Fig.29 In the example shown, the elastic body 510 is adhered to the main surface 200a of the cover 200 by the adhesive member 512, and the first fixing portion 410 is adhered to the elastic body 510 by the adhesive member 514. The second fixing portion 442 of the second anti-scattering component 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 anti-scattering component 400.

[0168] The attachment of the first fixing portion 410 of the first anti-scattering member 400 and the second fixing portion 442 of the second anti-scattering member 440 is not limited to adhesion. For example, the first fixing portion 410 of the first anti-scattering member 400 may be attached to the main surface 200a of the cover 200 by fixing with screws.

[0169] In the present embodiment, when viewed in cross section, the first anti-scattering member 400 has an L-shape in which the first shielding portion 420 is inclined at an acute angle relative to the rear direction of the display unit 100. Fig.30 As shown, when viewed in cross section, the first anti-scattering component 400 may have a T-shape in which the first shielding portion 420 is inclined at an acute angle relative to the rear direction of the display unit 100. This may make it more difficult for the first anti-scattering component 400 to fall off the cover 200. The second anti-scattering component 440 may have a T-shape, similar to the first anti-scattering component 400.

[0170] In the manufacturing method of the display device 10 in Embodiment 2, the first scattering prevention member 400 is attached to the main surface 200a of the cover 200 before the display unit 100 is provided on the main surface 200a of the cover 200. Fig.31As shown, the manufacturing method of the display device 10 in Embodiment 2 may include a step of arranging the display unit 100 on the main surface 200a of the cover 200 (step S210), a step of attaching the first anti-scattering component 400 to the cover 200 (step S220), and a step of accommodating 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 to which the adhesive 204 is applied on the display surface 110a is arranged on the main surface 200a of the cover 200. Then, the adhesive 204 is cured to adhere the display unit 100 to the cover 200. In step S220, while the first shielding portion 420 of the first anti-scattering component 400 is pressed on the side surface 136a of the display unit 100, the first anti-scattering component 400 is attached to the main surface 200a of the cover 200 by an adhesive member. Step S130 is the same as in Embodiment 2. As above, the display device 10 of Embodiment 2 can be manufactured.

[0171] In the embodiment, the cover 200 is attached to the side plate 320 of the housing 300. A configuration is possible in which the cover 200 is not attached to the housing 300. For example, the cover 200 may be attached to the instrument panel 600.

[0172] In Embodiments 1 to 6, the cover 200 has a flat plate shape. The cover 200 may be concavely curved in the +Z direction (passenger side), such as Fig.32 In addition, the cover 200 may be convexly curved in the +Z direction (passenger side).

[0173] The second anti-scattering member 440 may contact the side surface 136a of the display unit 100, similar to the first anti-scattering member 400. The second anti-scattering member 440 may press the side surface 136a of the display unit 100.

[0174] In Embodiment 6, the display device 10 includes two second anti-scattering components 440. Fig.33 As shown, the display device 10 may include a single second anti-scattering component 440. Fig.33 In the example shown, the second anti-scattering component 440 includes a single second fixing portion 442 and two second shielding portions 444. The two second shielding portions 444 are formed in a V shape. The second shielding portion 444 positioned on the -X side is inclined at an acute angle toward the side surface 136a side of the display unit 100 positioned on the -X side relative to the rear direction of the display unit 100 positioned on the -X side. In addition, the second shielding portion 444 positioned on the +X side is inclined at an acute angle toward the side surface 136a side of the display unit 100 positioned on the +X side relative to the rear direction of the display unit 100 positioned on the +X side. In this modified example, the spacing between the two display units 100 can be narrowed.

[0175] The first anti-scattering component 400 and the second anti-scattering component 440 are integrally formed. When viewed in a plan view, the integrally formed first anti-scattering component 400 and the second anti-scattering component 440 may surround the display unit 100. For example, Fig.34 As shown, the anti-scattering component 800 in which the first anti-scattering component 400 and the second anti-scattering component 440 are integrated can be formed in a U shape and surround one display unit 100. Fig.34 , the first anti-scattering member 400 and the anti-scattering member 800 (formed in a U-shape) surround one display unit 100 over the entire circumference of the display unit 100 .

[0176] For the purpose of explanation, some example embodiments have been described above. Although the foregoing discussion has presented specific embodiments, those skilled in the art will recognize that changes can be made in form and detail without departing from the broader spirit and scope of the present invention. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
