Description

[Technical field]

[0001] The present disclosure relates to a vehicle instrument panel, a vehicle display device, and a bezel body. [Background technology]

[0002] A virtual image display device serving as a head-up display device that projects an image onto a windshield is provided within an instrument panel (see, for example, Patent Document 1). The virtual image display device described in Patent Document 1 is provided within the instrument panel, and has an opening (hereinafter also referred to as an instrument panel opening) that passes the display light from the head-up display device to the windshield at a predetermined position of the instrument panel corresponding to the HUD opening that emits the display light in the head-up display device. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-98923 A Summary of the Invention [Problem to be solved by the invention]

[0004] The applicant has devised a head-up display device equipped with a driver monitoring device that detects the state of the observer (for details, see Patent Application No. 2020-164316. This technology is not publicly known). The head-up display device has a light-transmitting portion that transmits light for monitoring the driver (here, the light is infrared light) around the HUD opening that emits display light. In such a case, the instrument panel opening is formed so as to include the area of ​​the HUD opening and the area of ​​the light-transmitting portion on the inside.

[0005] 7 is composed of a head-up display device 910 attached to the back side of an instrument panel 900 (the side where driving devices such as an engine and a motor of a vehicle are provided) and an instrument panel opening 920 formed so as to include within its interior the HUD opening area and the light transmitting area of ​​the head-up display device 910. Due to the instrument panel opening 920, a part of the upper surface (hereinafter also referred to as a HUD exposed portion 911) including the HUD opening area and the light transmitting area of ​​the head-up display device 910 is exposed to the windshield 940 side.

[0006] The area surrounded by a dotted line indicated by reference symbol 951 indicates the shape of the instrument panel opening 920 (in other words, the shape of the HUD exposed portion 911 of the head-up display device 910 defined by the instrument panel opening 920) reflected on the front windshield 930, the colored area indicated by reference symbol 952 indicates the area of ​​the top cover (part of the housing of the head-up display device 910) of the head-up display device 910 included in the HUD exposed portion 911 reflected on the front windshield 930, the area surrounded by a dotted line indicated by reference symbol 953 indicates the area reflected on the front windshield 930 where a translucent cover to be provided on the HUD opening is positioned, and the area surrounded by a dotted line indicated by reference symbol 954 indicates the area of ​​the light-transmitting portion of the driver monitoring device reflected on the front windshield 930.

[0007] When the instrument panel opening 920 is formed to a minimum size including the area of ​​the HUD opening of the head-up display device 910 and the area of ​​the light transmitting portion, the area of ​​the light transmitting portion of the driver monitoring device protrudes from a rectangular shape along the roughly rectangular HUD opening (the light transmitting cover provided in the HUD opening). That is, the image 951 of the shape of the instrument panel opening 920 (in other words, the shape of the HUD exposed portion 911 of the head-up display device 910 defined by the instrument panel opening 920) has a first vertex 956 and a second vertex 957 that are convex inward. In such a case, when an image 951 of the shape of the instrument panel opening 920 (in other words, the shape of the HUD exposed portion 911 of the head-up display device 910 defined by the instrument panel opening 920) is viewed, the observer's visual attention is likely to be directed to the first vertex 956 and the second vertex 957, which are convex inward, which is expected to cause the observer to feel annoyed, and there is room for improvement. [Means for solving the problem]

[0013] [Outline of the vehicle's interior structure] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram of an interior structure of a vehicle 1 to which an embodiment of the present invention is applied. FIG. 2 is a cross-sectional view of a display device for a vehicle according to an embodiment of the present invention. FIG. 3 is a schematic diagram showing a main part including a frame part of FIG. 1. FIG. 4A and FIG. 4B are schematic diagrams of a display device for a vehicle according to an embodiment of the present invention seen from above. In these figures, the front window 20 and the instrument panel 10 in the interior structure are extracted and illustrated. In FIG. 4, arrows of "front" and "rear" in the longitudinal direction of the vehicle 1, arrows of "left" and "right" in the vehicle width direction, and arrows of "up" and "down" in the vehicle height direction are added. The arrows of "front", "rear", "up", "down", "left" and "right" added in the following figures follow the directional indications in FIG. 1.

[0014] 1 is disposed at the front of the vehicle compartment below the windshield 20 and extends across the entire width of the vehicle in the left-right direction. The instrument panel 10 is attached to the vehicle body and is provided on the rear side (vehicle compartment side) of the dash panel that separates the engine compartment from the vehicle compartment. The instrument panel 10 illustrated in this embodiment is a panel for a right-hand drive vehicle in which the driver's seat is located on the right side of the vehicle body.

[0015] A front windshield 20 is provided above the instrument panel 10 in a position inclined upward toward the rear. The front windshield 20 is gently curved so as to form a convex shape toward the front of the vehicle body in the vehicle width direction, and is fixed to the vehicle body by gluing its peripheral portion to the front edge of the roof of the vehicle body or the peripheral edge of the opening for the front windshield, such as a front pillar, although not shown.

[0016] The instrument panel 10 has a front cover 12 and a top cover 13 .

[0017] The facing cover 12 is arranged to face the driver's seat and the passenger seat of the instrument panel 10, and has a meter panel 14 including instruments equipped in the vehicle 1, and a center console 15 including air conditioning related parts, a navigation system, audio equipment, etc., fitted therein.

[0018] The top cover 13 is arranged to curve from the upper end of the facing cover 12 and extend outward (forward) from the vehicle compartment to the vicinity of the lower end of the front window 20. The top cover 13 on the driver's seat side of the vehicle 1 is provided with a frame portion 110 having a projection opening 111 through which display light 300 (see FIG. 2) projected from a HUD device 200 described later passes.

[0019] 2, a HUD device 200 is mounted on the rear side of the instrument panel 10 (below the top cover 13) to project display light 300 for image display toward the windshield 20 in a direction tilted backward (indicated by the dotted arrow in FIG. 2). The HUD device 200 is a well-known head-up display device that projects an image including various information to be presented to an observer (typically, the driver of the vehicle 1) onto the windshield 20 and superimposes the projected image on the scenery ahead of the vehicle 1 so that the observer can visually recognize the image as a virtual image.

[0020] The HUD device 200 emits display light 300 toward the windshield 20 (one example of a projection target member), and the windshield 20 reflects the display light 300 of the image displayed by the HUD device 200 toward the eye box 600. The HUD device 200 not only notifies an occupant of the vehicle 1 (the occupant is typically the driver of the vehicle 1) of information related to the vehicle 1 (hereinafter referred to as vehicle information) but also of information other than the vehicle information in an integrated manner. Note that the vehicle information includes not only information about the vehicle 1 itself but also information outside the vehicle 1 related to the operation of the vehicle 1.

[0021] Further, the "eye box" used in the description of this embodiment is: (1) an area in which the observer's eyes 700 (left eye 700L and / or right eye 700R) can see the entire virtual image V of the image, and at least a part of the virtual image V of the image cannot be seen outside the area; (2) an area in which at least a part of the virtual image V of the image can be seen, and at least a part of the virtual image V of the image cannot be seen outside the area; (3) an area in which at least a part of the virtual image V of the image can be seen with a predetermined luminance or more, and at least a part of the virtual image V of the image is less than the predetermined luminance outside the area; or (4) an area in which at least a part of the virtual image V can be viewed stereoscopically, and at least a part of the virtual image V cannot be viewed stereoscopically outside the area, when the HUD device 200 can display a virtual image V that can be viewed stereoscopically. That is, when the observer places his / her eyes (both eyes) outside the eye box 600, the observer cannot see the entire virtual image V of the image, the visibility of the entire virtual image V of the image is very low and difficult to perceive, or the virtual image V of the image cannot be viewed stereoscopically. The predetermined brightness is, for example, about 1 / 50 of the brightness of a virtual image of an image viewed at the center of the eyebox. The "eyebox" is set to be the same as the area (also called the iris) where the observer's viewpoint is expected to be located in the vehicle in which the HUD device 200 is mounted, or to include most of the iris (for example, 80% or more).

[0022] The HUD device 200 is composed of, for example, a spatial light modulation element (not shown) that generates an image, a relay optical system such as a plane mirror (not shown) and a concave mirror (not shown) that directs the light of the image displayed by the spatial light modulation element (hereinafter also referred to as image light) toward the projection target (front window 20), an actuator (not shown) that operates one or more relay optical systems, an accessory 250 described later, a control board (not shown) that controls the spatial light modulation element, the actuator, and the accessory 250, and a housing 210 that houses these.

[0023] The housing 210 is composed of an upper case 220 and a lower case 230 which have an engagement portion (not shown) which is engaged with a vehicle body frame (not shown) or the like arranged on the drive source (engine or motor) side of the vehicle 1 of the instrument panel 10 and are formed of a black light-shielding synthetic resin or the like. An HUD opening 221 is provided at approximately the middle in the front-rear direction of the upper case 220 when the HUD device 200 is mounted on the vehicle 1. The HUD opening 221 is covered by a light-transmitting cover 222 which is formed of, for example, a transparent light-transmitting synthetic resin or the like.

[0024] The light-transmitting cover 222 is formed in a thin plate shape using a highly transparent material such as glass, acrylic, or synthetic resin such as polycarbonate, and covers the HUD opening 221 of the HUD device 200. The light-transmitting cover 222 is arranged to be curved upward from the front side to the rear side of the vehicle 1 (FIG. 2). This makes it possible to prevent light that hits the light-transmitting cover 222 (for example, sunlight entering from outside the vehicle 1 through the windshield 20) from heading directly toward the observer's eyepoint.

[0025] For example, a lower case opening (not shown) is provided on the vehicle rear side of the lower case 230 of the housing 210. The lower case opening is provided in the lower case 230 so that the image light emitted from a display surface (for example, a display surface or a screen surface) of the spatial light modulation element attached to the outside of the housing 210 can enter the lower case opening.

[0026] 2, a plate-shaped light shielding portion 223 is provided at the rear end side of the HUD opening 221, extending forward and downward from the inner wall of the upper case 220 toward the inside (the inside side of the housing 210). The light shielding portion 223 is provided, for example, to prevent light from the outside of the housing 210, which enters through the HUD opening 221, from proceeding to the spatial light modulation element. Note that the example of the structure of the HUD device 200 is merely an example, and does not limit the structure of the HUD device 200 of the vehicle display device 100 in any way.

[0027] The attachment 250, like the light-transmitting cover 222 of the HUD device 200, is an electronic device that is disposed within the projection opening 111 of the instrument panel 10 at a position exposed on the windshield 20 side. An embodiment of the attachment 250 will be described below.

[0028] The accessory 250 in some embodiments is a driver monitoring device 251 that monitors one or more occupants of the vehicle 1 (e.g., observers of the HUD device 200), and includes an infrared irradiation unit (not shown) and a camera (not shown). The driver monitoring device 251 (an example of the accessory 250) is provided at a position adjacent to the translucent cover 222 in the vehicle width direction (left-right direction), as shown in Figs. 3 and 4.

[0029] An infrared light transmitting portion (not shown) that transmits infrared light is provided in a portion of the upper case 220 facing (corresponding to) the infrared light irradiation unit. The infrared light transmitting portion is made of, for example, a black printed layer that blocks visible light and transmits infrared light. The infrared light irradiation unit irradiates infrared light (near-infrared light) emitted by a light source formed of a light-emitting diode toward the front window 20 through the infrared light transmitting portion.

[0030] The camera, like the infrared light irradiation unit, is located adjacent to the light-transmitting cover 222 in the vehicle width direction (left-right direction) and is provided in front of the infrared light irradiation unit, as shown in Fig. 3, and is equipped with an imaging element having sensitivity to infrared light in the wavelength band irradiated from the infrared light irradiation unit and a lens that can transmit the infrared light and form an image on the imaging element, thereby taking a near-infrared image. Also, an infrared light transmitting portion (not shown) that transmits infrared light may be provided in a portion of the upper case 220 facing (corresponding to) the camera here, like the infrared light irradiation unit, to which the infrared light is transmitted. In some embodiments, the infrared light irradiation unit and the camera of the driver monitoring device 251 are assembled in a part of the inside of the housing 210 of the HUD device 200, but the present invention is not limited thereto. A sub-housing (not shown) for accommodating the infrared light irradiation unit and the camera of the driver monitoring device 251 may be provided separately from the housing 210 of the HUD device 200, and the sub-housing of the sub-projection device 252 may be assembled to the housing 210 of the HUD device 200. In addition, one of the infrared light irradiation unit and the camera of the driver monitoring device 251 may be assembled to the housing 210 of the HUD device 200 (or assembled in the sub-housing and then assembled to the housing 210 of the HUD device 200), and the other may be attached to a predetermined location of the vehicle 1 other than the housing 210 of the HUD device 200 (or the sub-housing). That is, the attachment 250 may include a configuration in which only one of the infrared light irradiation unit or the camera is included.

[0031] 3 and 4, the accessory 250 in some embodiments is a sub-projection device 252 that irradiates a second display light (not shown) different from the display light 300 from the HUD device 200 toward the windshield 20 and allows an observer to visually recognize an emission image due to the second display light reflected by the windshield 20, and has a translucent display member (not shown) and a light source (not shown) that illuminates the translucent display member. The sub-projection device 252 (an example of the accessory 250) is provided at a position adjacent to the translucent cover 222 in the vehicle width direction (left-right direction) as shown in FIGS.

[0032] The transparent design component is composed of a background portion (not shown) made of a light-shielding layer, and a cutout portion (not shown) of a predetermined design shape where the background portion is not partially formed. The background portion made of a light-shielding layer is composed of a printed layer printed on the surface of a transparent base material (not shown), and is printed using a means such as screen printing with black ink, for example. The cutout portion (in other words, the design portion) is formed as the cutout portion (the design portion) where the printed layer forming the background portion is not formed, by cutting out and printing the portion that forms the predetermined design when printing the background portion. The design portion is, for example, circular, but it goes without saying that any shape other than circular, such as a predetermined mark, can be adopted.

[0033] The light source is, for example, a chip-type light-emitting diode that emits red light, and is a light-emitting body that supplies illumination light (the emitted light) to the lens member 40. A lens may be provided between the light source and the transparent design member. The transparent design member, the light source (a board (not shown) on which the light source is mounted), and the lens of the sub-projection device 252 are assembled to a part of the inside of the housing 210 of the HUD device 200, but this is not limited thereto. A sub-housing (not shown) that houses the transparent design member, the light source (a board (not shown) on which the light source is mounted), and the lens of the sub-projection device 252 may be provided separately from the housing 210 of the HUD device 200, and the sub-housing of the sub-projection device 252 may be assembled to the housing 210 of the HUD device 200.

[0034] The sub-projector 252 (an example of the accessory 250) may include a transmissive display such as an LCD instead of the transmissive design member. This allows the emitted image visually recognized by the observer to be appropriately changed.

[0035] The accessory 250 has a secondary light-transmitting portion 255 formed by partially cutting out the surface of the upper case 220 (or the secondary housing) on ​​the windshield 20 side of the HUD device 200. When the accessory 250 is a driver monitoring device 251, the secondary light-transmitting portion 255 may be the infrared light-transmitting portion (a portion having a low transmittance (including blocking) of visible light and a high transmittance of infrared light), or may be a separate member provided on the windshield 20 side from the infrared light-transmitting portion. When the accessory 250 is a secondary projection device 252, the secondary light-transmitting portion 255 may be the transparent design member (a portion that transmits light in a portion and blocks light in another portion), or may be a separate member provided on the windshield 20 side from the transparent design member of the transparent display (a portion whose light transmittance is controlled by a processor).

[0036] The secondary light-transmitting portion 255 has a dark color tone and a curved shape with a predetermined curvature, and the curved shape may be set to have the curvature such that, for example, when sunlight (external light) hits the secondary light-transmitting portion 255 and is reflected, this reflected light (stray light) is not reflected toward the observer 700 through the front window 20.

[0037] Furthermore, in some embodiments, the secondary light transmitting portion 255 may have a stray light suppression cover (not shown) on a surface side (front window 20 side) facing (corresponding to) the secondary light transmitting portion 255. The stray light suppression cover has a dark color tone and a curved shape with a predetermined curvature, and the curved shape is set to have the curvature such that, for example, when sunlight (external light) hits the stray light suppression cover and is reflected, the reflected light is not reflected toward the observer 700 side via the front window 20.

[0038] The auxiliary light-transmitting section 255 of the accessory 250 (driver monitoring device 251 and indicator display unit 252) is provided at a position that does not overlap with the optical path of the display light 300 from the spatial light modulation element toward the relay optical system and the optical path of the display light 300 from the relay optical system toward the front window 20, and is provided around the light-transmitting cover 222.

[0039] The secondary light transmitting portion 255 of the accessory 250 (driver monitoring device 251 or indicator display unit 252) may be disposed at a position where it does not overlap with the display light 300, and the secondary light transmitting portion 255 of some embodiments may be disposed at a peripheral portion (not shown) inside the outer edge of the translucent cover 222 through which the display light 300 does not pass. That is, in this case, the secondary light transmitting portion 255 may be provided at a position where it overlaps with a part of the translucent cover 222 of the HUD device 200. Furthermore, the stray light suppression cover of the secondary light transmitting portion 255 may be provided in a part of the translucent cover 222 of the HUD device 200.

[0040] 2 and 3, the instrument panel 10 has a frame portion 110 in a part of the top cover 13. The frame portion 110 is provided with a projection opening 111 through which the display light 300 (see FIG. 2) projected from the HUD device 200 passes. The projection opening 111 is formed by a cylindrical inner peripheral wall portion 112 that extends downward from the surface of the top cover 13 toward the HUD device 200.

[0041] The projection opening 111 of the frame 110 conceals a part of the HUD device 200 by the inner peripheral wall 112 so as not to be exposed on the windshield 20 side, and exposes the other part of the HUD device 200 on the windshield 20 side. Here, the area of ​​the HUD device 200 that is not concealed by the projection opening 111 of the frame 110 and is exposed on the windshield 20 side is referred to as a HUD exposed part S. The HUD exposed part S includes a part of the upper case 220, the light-transmitting cover 222, and the accessory 250. In other words, the frame 110 is formed such that the HUD exposed part S including the part of the upper case 220, the light-transmitting cover 222, and the accessory 250 is disposed inside the projection opening 111.

[0042] In some embodiments, the secondary light-transmitting portion 255 of the accessory 250 (driver monitoring device 251 or indicator display unit 252) is provided at a position adjacent to the right side of the translucent cover 222 as shown in Fig. 4A, and is formed so that the length L22 in the front-rear direction is longer than the length L21 in the left-right direction (i.e., the length L2A of the long side of the secondary light-transmitting portion 255 is the length L22 in the front-rear direction). The length L2A of the long side of the secondary light-transmitting portion 255 is set shorter than the length L12 of the translucent cover 222 in the direction along the length L2A of the long side of the secondary light-transmitting portion 255 (front-rear direction). The frame portion 110 of the vehicle display device 100 of this embodiment surrounds the area of ​​the light-transmitting cover 222 and the area of ​​the secondary light-transmitting portion 255 of the accessory 250 inside the projection opening 111, and is formed as a convex hexagon (an example of a convex polygon) with an interior angle of 180 degrees or less in the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111). The shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 partitioned by the projection opening 111) is formed into a convex hexagon (an example of a convex polygon) by providing a substantially pentagonal exposed excess region S10 surrounded by the translucent cover 222, the secondary light transmitting portion 255, and the inner peripheral wall portion 112 (frame portion 110) in a direction along the long side L2A of the secondary light transmitting portion 255 in the longitudinal direction or lateral direction of the vehicle 1 (here, the longitudinal direction) in the HUD exposed portion S. In some embodiments, the exposed excess region S10 includes a first exposed excess region S11 arranged in front of the secondary light transmitting portion 255, and a second exposed excess region S12 arranged in the rear of the secondary light transmitting portion 255. The exposed excess region S10 has a length in a direction not along the long side L2A of the secondary light transmitting portion 255 in the front-rear direction or left-right direction of the vehicle 1 (here, the left-right direction) that is shortest at the farthest part of the secondary light transmitting portion 255 (in the first exposed excess region S11, the front end which is the farthest part of the secondary light transmitting portion 255 is shortest, and in the second exposed excess region S12, the rear end which is the farthest part of the secondary light transmitting portion 255 is shortest). Note that this is not limited, and the exposed excess region S10 may be only one of the first exposed excess region S11 or the second exposed excess region S12.

[0043] In the above embodiment, the secondary light transmitting portion 255 is provided at a position adjacent to the translucent cover 222 in the left-right direction as shown in FIG. 3 and FIG. 4A, but is not limited thereto and may be provided at a position adjacent to the translucent cover 222 in the front-rear direction. In some embodiments, the secondary light transmitting portion 255 of the attachment 250 (driver monitoring device 251 or indicator display unit 252) is provided at a position adjacent to the front side of the translucent cover 222 as shown in FIG. 4B, and is formed so that the length L21 in the left-right direction is longer than the length L22 in the front-rear direction (i.e., the length L2A of the long side of the secondary light transmitting portion 255 is the length L21 in the left-right direction). The length L2A of the long side of the secondary light transmitting portion 255 is set to be shorter than the length L11 of the translucent cover 222 in the direction along the length L2A of the long side of the secondary light transmitting portion 255 (left-right direction). The frame portion 110 of the vehicle display device 100 of this embodiment surrounds the area of ​​the light-transmitting cover 222 and the area of ​​the secondary light-transmitting portion 255 of the accessory 250 inside the projection opening 111, and is formed as a convex hexagon (an example of a convex polygon) with an interior angle of 180 degrees or less in the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111). The shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 partitioned by the projection opening 111) is formed into a convex hexagon (an example of a convex polygon) by providing a substantially pentagonal exposed excess region S10 surrounded by the translucent cover 222, the secondary light transmitting portion 255, and the inner peripheral wall portion 112 (frame portion 110) in a direction along the long side L2A of the secondary light transmitting portion 255 in the front-rear direction or left-right direction of the vehicle 1 (here, the left-right direction). In some embodiments, the exposed excess region S10 includes a third exposed excess region S13 arranged to the left of the secondary light transmitting portion 255, and a fourth exposed excess region S14 arranged to the right of the secondary light transmitting portion 255. The exposed excess region S10 has a length in a direction (here, the front-to-rear direction) that is not aligned with the long side L2A of the secondary light transmitting portion 255 in the front-to-rear or left-to-right direction of the vehicle 1, which is shortest at the farthest point of the secondary light transmitting portion 255 (in the third exposed excess region S13, the leftmost end which is the farthest point of the secondary light transmitting portion 255 is shortest, and in the fourth exposed excess region S14, the rightmost end which is the farthest point of the secondary light transmitting portion 255 is shortest).However, without being limited thereto, the exposed extra region S10 may be only one of the third exposed extra region S13 and the fourth exposed extra region S14.

[0044] In the above embodiment, the projection opening 111 of the frame 110 of the vehicle display device 100 is a convex hexagon, but is not limited thereto and may be a convex pentagon as shown in FIG.

[0045] As described above, the frame 110 of the vehicle display device 100 of this embodiment is formed as a convex polygon in which the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111) has an interior angle of 180 degrees or less. Specifically, for example, the shape of the projection opening 111 of the frame 110 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111) is formed as a convex hexagon as shown in FIG. 3, FIG. 4A, or FIG. 4B. In addition, since some or all of the sides forming the projection opening 111 may be changed to curves other than straight lines, the frame portion 110 of the vehicle display device 100 of this embodiment may, in a broad sense, be formed as a convex closed figure in which the entirety of a line segment connecting any two points on the boundary of the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111) is a point inside or on the boundary of the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111).

[0046] Next, an example of the operation of the vehicular display device 100 of this embodiment will be described with reference to FIG. 6. FIG. 6 shows a schematic diagram of an image projected onto the windshield 20 by the vehicular display device 100 of this embodiment. The area surrounded by a dotted line and indicated by the symbol E10 (hereinafter also referred to as a first image) indicates the shape of the projection opening 111 reflected on the windshield 20 (in other words, the shape of the HUD exposed portion S of the HUD device 200 partitioned by the projection opening 111), the colored area indicated by the symbol E20 (hereinafter also referred to as a second image) indicates the area of ​​the upper case 220 included in the HUD exposed portion S reflected on the windshield 20, and the area surrounded by a dotted line and indicated by the symbol E30 (hereinafter also referred to as a third image) indicates the area of ​​the translucent cover 220 reflected on the windshield 20. 222 is arranged, the area surrounded by dotted lines indicated by symbol E40 (hereinafter also referred to as the fourth image) indicates a part or all of the area of ​​the display surface of the spatial light modulation element via the relay optical system of the HUD device 200 reflected on the windshield 20 (in other words, the area (area of ​​the optical path) through which the display light 300 emitted from the display surface of the spatial light modulation element passes), and the area surrounded by dotted lines indicated by symbol E50 (hereinafter also referred to as the fifth image) indicates the area of ​​the secondary light-transmitting portion 255 of the attachment 250 reflected on the windshield 20.

[0047] Each part of the HUD device 200 (the surface and inside of the upper case 220, the inside of the housing 210, and the stray light suppression cover arranged on the surface of the secondary light transmitting portion 255 of the accessory 250) is subjected to a low reflection treatment, for example, a fine embossing or a black painting or printing, so that when viewed from the viewing area (eye box 600) of the HUD device 200, the first image E10, the second image E20, the third image E30, the fourth image E40, and the fifth image E50 are difficult to view, and it is preferable that only the virtual image V based on the display light 300 from the spatial light modulation element is superimposed on the front window 20 and viewed, but in reality, these images E10 to E50 can be viewed by the viewer under one or more conditions such as the viewer's eye position, the intensity and direction of incident external light, etc. However, since the frame portion 110 of the vehicle display device 100 of this embodiment has the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111) formed as a convex polygon (in a broader sense, a convex closed figure), the shape of the projection opening 111 (in other words, the first image E10 of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111) does not have a vertex (an inwardly recessed portion) with an interior angle greater than 180 [degrees], it is possible to prevent the viewer's visual attention from being drawn to the recessed portion.

[0048] As described above, the vehicle display device 100 of the first embodiment is composed of the head-up display device 200 and the frame portion 110 provided with the projection opening 111 through which the display light projected by the head-up display device 200 toward the windshield 20 passes. The head-up display device 200 has the spatial light modulation element for emitting the display light 300, the HUD opening portion 221 for emitting the display light 300 to the projection opening 111, and at least the housing 210 for partitioning the optical path of the display light 300 from the spatial light modulation element to the HUD opening portion 221, and the secondary light transmitting portion 255 for inputting and / or outputting the light, which is disposed at a position shifted from the HUD opening portion 221. The projection opening 111 of the frame portion 110 is a projection opening 111 of the HUD opening portion 221. The projection opening 111 is formed of a convex closed figure surrounding the area of ​​the projection opening 111, and the area of ​​the secondary light transmitting portion 255. According to this, the entire line segment connecting any two points on the boundary of the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111) is a convex closed figure that is a point inside or on the boundary of the shape of the projection opening 111 (in other words, the shape of the HUD exposed portion S of the HUD device 200 defined by the projection opening 111). Therefore, since it does not have a vertex (inwardly recessed recess) with an interior angle greater than 180 degrees, it is possible to prevent the observer's visual attention from being drawn to the recess, and ultimately it is possible to make it easier to view the image (virtual image V) of the HUD device 200 and the real scene (foreground) on which the image (virtual image V) of the HUD device 200 is overlapped.
