  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  A vehicle display device 100 according to an embodiment of the present invention is mounted on a vehicle 1. Specifically, the vehicle display device 100 shown in FIGS. 1 and 2 has a center portion corresponding to the space between the driver seat 4a and the passenger seat 4b arranged in the left-right direction DH of the vehicle 1 in the instrument panel 2 of the vehicle 1. 3 is installed. For example, the vehicle display device 100 can display an image using the image display panel 30 toward the viewing side where the driver seated in the driver's seat 4a and the passenger seated in the passenger seat 4b are located. It has become. In the vehicle 1, eyelips ELP are set for each of the right eye and the left eye based on an eye range that statistically represents the distribution of the positions of the eyes of the driver (see JIS D0021: 1998). The vehicle display device 100 performs display so that a driver whose eyes are located in such an eyelips ELP and a passenger on the passenger seat 4b can easily see.

  In addition, the vertical direction DV of the vehicle 1 in this embodiment shows the direction along the gravity direction when the vehicle 1 travels on a flat ground or stops on a flat ground. The left-right direction DH of the vehicle 1 is a direction orthogonal to the up-down direction DV of the vehicle 1 and indicates the width direction of the vehicle 1.

  The vehicle display device 100 also functions as an operation device that allows a driver and a passenger in the passenger seat 4b to perform a touch operation as an operator.

  Such a vehicle display device 100 will be described in detail below with reference to FIGS. As shown in FIG. 3, the vehicle display device 100 mainly includes an image display panel 30, an exposed translucent plate 40, a touch detection unit 50, a holding frame 60, a translucent medium unit 70, and a control unit 20.

  As shown in FIGS. 3 to 5, the image display panel 30 is a flat display element that displays an image. In the present embodiment, the image display panel 30 is a liquid crystal panel using thin film transistors (TFTs), and an active matrix having a display surface portion 32 formed by a plurality of display pixels arranged in a two-dimensional direction. A liquid crystal panel is used.

  More specifically, the display surface portion 32 on the inner peripheral side of the reflection surface 80 described later has a rectangular shape having a display surface 32a on the viewing side. A pair of polarizing plates and a liquid crystal layer sandwiched between the pair of polarizing plates are stacked inside the display surface portion 32. The pair of polarizing plates are arranged so that their polarization axes are substantially perpendicular to each other. In the liquid crystal layer, the polarization direction of light incident on the liquid crystal layer can be rotated according to the applied voltage by applying a voltage for each display pixel. In this way, it is possible to control the transmittance of incident light for each display pixel.

  A backlight is disposed on the back side opposite to the viewing side with respect to the display surface portion 32, and the light incident on the display surface portion 32 from the backlight is controlled in transmittance, whereby the image display panel. The display surface portion 32 of 30 is configured to display a real image. Here, the light of the image is emitted from each pixel of the display surface portion 32 in each direction on the viewing side with a predetermined distribution. In this manner, a bright and real image can be displayed even for a driver whose eyelips ELP is positioned in an oblique direction on the viewing side with respect to the image display panel 30.

  Further, the image display panel 30 has a surrounding frame portion 34. The surrounding frame portion 34 is formed by processing a metal plate such as iron or aluminum by pressing or the like, and surrounds the display surface portion 32 and the backlight from the outer peripheral side. Since the surrounding frame portion 34 surrounds the display surface portion 32, the display surface portion 32 is arranged on the inner peripheral side on the surface facing the viewing side of the image display panel 30, that is, on the surface facing an exposed translucent plate 40 described later. On the outer peripheral side of the display surface portion 32, the surrounding frame portion 34 is disposed so as to protrude toward the viewing side with respect to the display surface 32a.

  Such a rectangular image display panel 30 is arranged such that its longitudinal direction is along the vertical direction DV of the vehicle 1 and its short side direction is along the horizontal direction DH of the vehicle 1 (see FIG. 2).

  The exposed translucent plate 40 is a translucent translucent plate formed in a rectangular shape by, for example, acrylic resin or polycarbonate resin, as shown in FIGS. 2 to 5. In this embodiment, the exposed translucent plate is colored with smoke. Therefore, the transmittance is 70 to 80%. The thickness of the exposed translucent plate 40 is substantially uniform at each location. Further, a hard coat layer for preventing scratches is formed on the visible side surface of the exposed translucent plate 40, and a mask printing layer having a light shielding property is formed in black on the outer edge portion of the exposed translucent plate 40. The light shielding edge 42 is provided. The exposed translucent plate 40 is disposed on the most visible side in the apparatus and is formed in a curved plate shape that is exposed on the visible side. Thus, the exposed translucent plate 40 transmits the image light from the image display panel 30 to the viewing side.

  Similar to the image display panel 30, the rectangular exposed translucent plate 40 is arranged with the longitudinal direction along the vertical direction DV of the vehicle 1 and the short side direction along the left-right direction of the vehicle 1. (See FIG. 1). Here, it is formed in a concave shape that is recessed toward the image display panel 30 side (that is, the back side).

  As shown in FIGS. 3 to 5, the touch detection unit 50 includes a projected capacitive touch switch 52, and the touch switch 52 is formed in a translucent film shape. The touch switch 52 is bonded to the back side of the exposed translucent plate 40 via an optical transparent adhesive sheet (Optically Clear Adhesive, OCA). The touch detection unit 50 detects a touch operation on the exposed translucent plate 40 with the touch switch 52. Specifically, when an operator's finger approaches or comes into contact with the exposed translucent plate 40, the touch detection unit 50 detects a change in capacitance by the touch circuit 24 described later, whereby the finger on the exposed translucent plate 40 is detected. The position of can be specified.

  Between the image display panel 30 and the exposed translucent plate 40 and the touch detection unit 50, the exposed translucent plate 40 is formed in a curved plate shape with respect to the planar image display panel 30. Thus, as shown in FIG. 4, an internal region AR is formed, and a step HD is formed on the outer peripheral side.

  As shown in FIGS. 2 to 5, the holding frame 60 is an opening frame that is formed of, for example, black synthetic resin and has a large opening in the center according to the shape of the image display panel 30. The holding frame 60 is opened by surrounding the inner region AR from the outer peripheral side. At the same time, the viewing end 60a of the holding frame 60 holds the light shielding edge 42 from the back side. Thereby, the positions of the exposed translucent plate 40 and the image display panel 30 are fixed.

  Here, the height dimension HF of the holding frame 60 from the display surface 32a of the image display panel 30 to the viewing side end 60a is formed in accordance with the step HD on the outer peripheral side caused by the curved surface of the exposed translucent plate 40. However, it differs depending on the location. Specifically, as the exposed translucent plate 40 is bent in the vertical direction DV of the vehicle 1, the height dimension HF increases as the position is shifted from the central portion 60b in the vertical direction DV. And the height dimension HF is the maximum in the edge part of the up-down direction DV. In addition, even in the central portion 60b where the height dimension HF is minimized, a height dimension HF of a predetermined level or more is secured in accordance with the formation of a light transmitting medium portion 70 described later, and the image display panel 30 and the exposed light transmitting light are transmitted. The plates 40 are not in direct contact with each other and are separated from each other.

  As shown in FIGS. 3 to 5, the translucent medium part 70 is formed in the internal area AR surrounded by the holding frame 60 and transmits the image light from the image display panel 30. The translucent medium part 70 includes an opposing wall 72 and a medium filling layer 74.

  The opposing wall 72 is an outer edge wall formed with translucency by, for example, an acrylic resin. The facing wall 72 is along the facing portion facing the holding frame 60 in the internal region AR between the edge of the display surface portion 32 of the image display panel 30 and the light shielding edge 42 of the exposed translucent plate 40. A rectangular ring with a large opening at the center. At the same time, the opposing wall 72 is provided in contact with the edge portion of the display surface portion 32 and the light shielding edge portion 42, thereby closing the space between the image display panel 30 and the exposed translucent plate 40 over the entire circumference. Yes. The facing wall 72 is provided so as to extend substantially perpendicular to the display surface 32a. A gap 88 is provided between the holding frame 60 and the opposing wall 72 over the entire circumference.

  The medium filling layer 74 is a translucent medium layer filled in the inner region AR from the opposing wall 72 in the inner region AR. The medium filling layer 74 is filled with an optical transparent resin (Optically Clear Resin, OCR) as a translucent medium, for example, a silicon resin is employed. The medium filling layer 74 is filled in a solid state without substantial gaps in the inner region AR surrounded by the image display panel 30, the exposed translucent plate 40, and the opposing wall 72, so that the image display panel 30 side is filled. The contact interfaces 74a, 74b, and 74c are formed on the exposed translucent plate 40 side and the opposing wall 72, respectively.

  The translucent medium part 70 is provided with a reflecting surface 80 as a reflecting part shown in an enlarged manner in FIG. 5 on an opposing wall 72 formed to include an opposing part. Specifically, the reflecting surface 80 is provided as an interface with the gap 88 in the facing wall 72.

  The reflective surface 80 is provided so that the tangential direction intersects with the display surface 32a. Specifically, since the opposing wall 72 extends substantially perpendicular to the display surface 32a, the tangential direction of the reflective surface 80 is also substantially perpendicular to the display surface 32a. Further, due to the disposition of the facing wall 72 described above, the reflecting surface 80 is disposed in contact with the display surface 32 a along the edge of the display surface portion 32 on the inner peripheral side with respect to the surrounding frame portion 34.

  The reflection surface 80 is configured to mirror-reflect the image light from the image display panel 30 in a state where the reflection surface 80 is disposed between the edge of the display surface 32 and the light shielding edge 42 in the internal region AR. Yes. By this mirror reflection, the reflecting surface 80 can display the inverted image Irv outside the display surface portion 32.

  Hereinafter, the reverse image Irv will be described in detail. As shown in FIG. 4, the inverted image Irv is displayed as a virtual image obtained by inverting the image when the image displayed on the display surface 32 a of the display surface unit 32 is reflected by the reflecting surface 80. Here, since the area of the reflection surface 80 of the present embodiment is smaller than the area of the display surface 32a, more specifically, the inverted image Irv is displayed in the reflection target area Arv of the display surface 32a. The displayed image is inverted and displayed as a virtual image.

  Here, the reflection target area Arv shown in FIG. 6 can be calculated based on the eye range and the mounting position of the vehicle display device 100. As an example, a tangent line circumscribing the eyelips ELP set based on the eye range, and a tangent line passing through the viewing-side end portion 80a of the reflecting surface 80 (see the two-dot chain line in FIG. 1) is calculated. Then, among the light rays emitted from the display surface 32a, the light rays that pass through the tangent line after the reflection by the reflection surface 80 are calculated. The calculation of the light beam can be performed by, for example, a light beam tracing method or a simple method that substitutes this. The emission point of the light ray thus calculated on the display surface 32a is estimated as a boundary between the reflection target region Arv and the reflection target region Arv on the display surface 32a.

  For example, in the present embodiment, on one side of the left-right direction DH of the vehicle 1, the display surface 32 a is at an angle of about 40 to 50 ° with respect to the normal direction of the reflecting surface 80 from the viewing-side end 80 a of the corresponding reflecting surface 80. The intersection of the straight line toward the display surface 32a and the display surface 32a is a boundary between the reflection target region Arv and the reflection target region Arv on the display surface 32a. In this way, light from the reflection target area Arv in the display surface 32a can be reflected by the reflection surface 80 and reach the eyelips ELP. Further, the reflection surface 80 is adjacent to the reflection target region Arv by being in contact with the display surface 32a.

  As shown in FIG. 3 in particular, the control unit 20 includes a touch circuit 24 and a main circuit 26 mounted on a circuit board 22. The touch circuit 24 includes a CPU, a memory, and the like, and is a control circuit that controls the electrically connected touch detection unit 50. The touch circuit 24 processes the detection signal input from the touch detection unit 50 and outputs the detection signal to the electrically connected main circuit 26. The main circuit 26 includes a CPU, a memory, and the like, and is a control circuit that controls the electrically connected image display panel 30. The main circuit 26 outputs an image display signal based on input signals from various devices of the vehicle 1 that can communicate with each other and detection signals from the touch detection unit 50, so that the display contents of the image display panel 30 are displayed. To control.

  The circuit board 22 is fastened to the back side of the image display panel 30 by screws 12 and spacers 14 together with the back side housing 10.

  Next, an image controlled by the control unit 20 and displayed as a real image on the display surface unit 32 will be specifically described. In the apparatus 100, the image that is displayed as a real image on the display surface portion 32 includes the information display image Ii. Examples of the information display image Ii include an operation image Ii1 used for operation of the vehicle 1 or the image display panel 30, a character Ii2 representing information, a map Ii3, a television image, and the like.

  Examples of the operation image Ii1 include a button image used for an air conditioning setting operation in a passenger compartment, a button image for using a navigation function, and a button image for using an audio function. When the operator performs a touch operation on these operation images Ii1, the touch detection unit 50 detects a touch operation on the operation image Ii1, and the settings of various devices of the vehicle 1 are changed according to the operation image Ii1, The image displayed on the display surface portion 32 changes.

  The characters Ii2 include characters representing the air conditioning setting state, characters representing the audio setting state, characters representing the state of the vehicle 1 such as vehicle speed and fuel consumption, characters representing the state outside the vehicle such as traffic information, and e-mail characters. Can be mentioned.

  Each illustrated information display image Ii may be displayed constantly or may be temporarily displayed according to a touch operation or the like.

  Examples of the image not corresponding to the information display image Ii include various background images Ib1, Ib2, Ib3, and Ib4. The background images Ib1, Ib2, Ib3, and Ib4 are displayed as backgrounds for the information display image.

  FIG. 7 shows an example of display. The plain background image Ib1 whose direction dependency is limited is displayed as a real image both in the reflection target area Arv and outside the reflection target area Arv. In addition, an “AUTO” button image used for air conditioning setting as the operation image Ii1 and a character “Ii2” “75” representing information are displayed as a real image outside the reflection target area Arv.

  Therefore, on the display surface 32a, the information display image Ii and the background image Ib1 are displayed as real images outside the reflection target area Arv, and only the background image Ib1 is displayed as a real image within the reflection target area Arv. A reverse image Irv obtained by inverting the background image Ib1 in the reflection target area Arv is displayed as a virtual image outside the display surface portion 32 by the reflection surface 80 along the edge of the display surface portion 32. Therefore, only the plain background image Ib1 is reflected in the inverted image Irv, and the information display image Ii is not reflected.

  In this example, regarding the display position of the information display image Ii, the display hidden area Adh in which the display is hidden by the light shielding edge 42 of the exposed translucent plate 40 in the display surface 32a is also considered. Specifically, since the information display image Ii is displayed as a real image outside the reflection target area Arv and outside the display hidden area Adh, both the driver and the passenger on the passenger seat 4b can directly view the information display image Ii. It is like that.

  FIG. 8 shows another example of display. The background image Ib2 of the fabric pattern with limited direction dependency is displayed as a real image both inside the reflection target area Arv and outside the reflection target area Arv. In addition, an “AUTO” button image used for air conditioning setting as the operation image Ii1 and a character “Ii2” “75” representing information are displayed as a real image outside the reflection target area Arv.

  Therefore, as shown in FIG. 9, the information display image Ii and the background image Ib2 are displayed as real images outside the reflection target area Arv in the display surface 32a, and only the background image Ib2 is a real image within the reflection target area Arv. It is displayed. A reverse image Irv obtained by inverting the background image Ib2 in the reflection target area Arv is displayed as a virtual image outside the display surface 32 by the reflection surface 80 along the edge of the display surface 32. Therefore, the fabric image background image Ib2 is reflected in the inverted image Irv, and the information display image Ii is not reflected. In this example as well, the display hidden area Adh is taken into consideration as in the above example.

  In the present embodiment, the background images Ib1 and Ib2 whose direction dependency is limited are backgrounds that can be substantially identified with the image before rotation, for example, even when the image is rotated vertically and horizontally. An image is shown.

  FIG. 10 shows another example of display. The striped background image Ib3 is displayed as a real image both in the reflection target area Arv and outside the reflection target area Arv. The outline OL of the striped pattern in the background image Ib3 intersects the extending direction DE of the boundary portion 82 perpendicularly at the boundary portion 82 with the reflecting surface 80. In addition, an “AUTO” button image used for air conditioning setting as the operation image Ii1 and a character “Ii2” “75” representing information are displayed as a real image outside the reflection target area Arv. In FIG. 10, only a part of the contour line OL is given a reference numeral.

  Therefore, as shown in FIG. 11, the information display image Ii and the background image Ib3 are displayed as real images outside the reflection target area Arv on the display surface 32a, and only the background image Ib3 is displayed as a real image within the reflection target area Arv. It is displayed. A reverse image Irv obtained by inverting the background image Ib3 in the reflection target area Arv is displayed as a virtual image outside the display surface 32 by the reflection surface 80 along the edge of the display surface 32. Therefore, only the striped background image Ib3 is reflected in the inverted image Irv, and the information display image Ii is not reflected. In this example as well, the display hidden area Adh is taken into consideration as in the above example.

  FIG. 12 shows another example of display. A map Ii3 is displayed as a real image as an information display image Ii in a part outside the reflection target area Arv. On the other hand, the blurred image Ib4 is displayed as a real image as a background image in the reflection target area Arv. The blurred image Ib4 is created by blurring the map that is the information display image Ii. Here, the blurring process in the present embodiment is a process that makes it difficult to discriminate the original display content by blurring the contour line or the like of the original image. As a result, the blurred image Ib4 is viewed as if it has passed through the frosted glass, and it is extremely difficult to determine the information of the original map Ii3.

  Further, an interpolation image Iip is displayed as a real image continuously from the blurred image Ib4 and the map Ii3 as the information display image Ii in a portion adjacent to the reflection target region Arv outside the reflection target region Arv on the display surface 32a. Yes. The interpolated image Iip is an image created by blurring the map Ii3 that is the information display image Ii. The blurring degree of the interpolated image Iip gradually increases in a gradation so as to approach the blurring degree in the blurred image Ib4 as it approaches the reflection target area Arv. Here, the blurring degree in the present embodiment is the degree of the blurring effect in the blurring process, and it is assumed that the outline of the original image becomes more blurred as the blurring degree increases.

  In the present embodiment, at the boundary between the interpolated image Iip and the blurred image Ib4, the blurring degree of the interpolated image Iip substantially matches that of the blurred image Ib4, so it is difficult to determine the information of the original map Ii3. On the other hand, since the blurring degree is extremely low at the boundary between the interpolated image Iip and the map Ii3, it is easy to determine the information of the original map Ii3.

  Therefore, as shown in FIG. 13, the map Ii3 and the interpolated image Iip as the information display image Ii are displayed as a real image outside the reflection target area Arv in the display surface 32a, and the background image is displayed in the reflection target area Arv. Only the blurred image Ib4 is displayed as a real image. A reverse image Irv obtained by inverting the blurred image Ib4 in the reflection target area Arv is displayed as a virtual image outside the display surface 32 by the reflection surface 80 along the edge of the display surface 32. Therefore, in the reverse image Irv, only the blurred image Ib4 as the background image is reflected, and the map Ii3 and the interpolated image Iip as the information display image Ii are not reflected.

  In FIG. 12, the display range of the blurred image Ib4 is indicated by hatching where diagonal lines intersect, and the display range of the interpolated image Iip is indicated by diagonal line hatching in only one direction. Further, in FIG. 12, a map picture is shown under each hatching, but in practice, a blurring process according to the above-described blurring degree is performed. In FIG. 13, the inverted image Irv is also hatched with diagonal lines intersecting, and this is an expression showing that the inverted image Irv is also blurred in the same manner as the blurred image Ib4. .

(Function and effect)
The operational effects of the present embodiment described above will be described below.

  According to the present embodiment, in the vehicle display device 100 mounted on the vehicle 1, the display surface portion 32 of the image display panel 30 displays an image as a real image. Further, the reflection surface 80 is disposed at the edge of the display surface portion 32. The reflection surface 80 reflects light from the reflection target area Arv in the display surface portion 32. Thereby, since the reverse image Irv is displayed as a virtual image outside the display surface portion 32, it is possible to give a sense of spreading to the display.

  Here, the information display image Ii in the image is displayed outside the reflection target area Arv in the display surface portion 32. Therefore, even if the reflection surface 80 reflects light from the reflection target area Arv, the information display image Ii is displayed. Is suppressed from being reflected in the inverted image Irv. Therefore, by avoiding the viewer from being confused by the inverted image Irv, the visibility of the display content is improved, and information is easily understood accurately.

  Further, according to the present embodiment, the light-transmitting plate 40 that is formed in a curved surface exposed on the viewing side and transmits the image is provided, and the reflecting surface 80 is provided between the image display panel 30 and the light-transmitting plate 40. Be placed. By doing so, even when the internal region AR corresponding to the curved surface of the exposed light transmitting plate 40 is formed between the image display panel 30 and the exposed light transmitting plate 40, the edge of the display surface portion 32 is formed. Since the reflection surface 80 arranged along the line displays the inverted image Irv, it is difficult to confirm the level difference between the image display panel 30 and the exposed translucent plate 40 on the outer periphery of the area AR. That is, it is difficult to recognize the presence of the image display panel 30 on the back side of the exposed translucent plate 40. Therefore, by sufficiently exhibiting the curved surface feeling of the exposed translucent plate 40, the visibility of the device 100 is improved while improving the appearance of the device 100.

  Further, according to the present embodiment, the information display image Ii includes the operation image Ii1 used for the operation of the vehicle 1 or the image display panel 30. If the operation image Ii1 is reflected in the reverse image Irv, not only the visibility is deteriorated, but also a smooth operation is hindered. However, since the information display image Ii is displayed outside the reflection target area Arv, even if the reflection surface 80 reflects light from the reflection target area Arv, reflection of the operation image Ii1 on the inverted image Irv is suppressed. As a result, visibility is improved and smooth operation is possible.

  Further, according to the present embodiment, the touch detection unit 50 that detects a touch operation on the operation image Ii1 is provided. In such an apparatus 100, if the operation image Ii1 is reflected in the inverted image Irv, the operator may be confused by the inverted button image and touch the inverted image Irv. . However, in the present embodiment in which the information display image Ii is displayed outside the reflection target area, even if the reflection surface 80 reflects light from the reflection target area Arv, the operation image Ii1 is reflected in the inverted image Irv. It is suppressed and visibility increases. The operator does not have to make a mistake in the position of the touch operation.

  Further, according to the present embodiment, the information display image Ii includes the character Ii2. If the character Ii2 is reflected in the inverted image Irv, the inverted character is displayed and is difficult to read, and the visibility deteriorates. However, in the present embodiment in which the information display image Ii is displayed outside the reflection target area Arv, even if the reflection surface 80 reflects the light from the reflection target area Arv, the character Ii2 is reflected in the inverted image Irv. As a result, the deterioration of the legibility of the character Ii2 is suppressed, and the visibility is improved.

  Further, according to the present embodiment, the information display image Ii includes the map Ii3. If the map Ii3 is reflected in the reverse image Irv, the viewer misunderstands that the road where the virtual image is displayed is reversed from the road where the real image is displayed, for example. However, in the present embodiment in which the information display image Ii is displayed outside the reflection target area Arv, even if the reflection surface 80 reflects light from the reflection target area Arv, the map Ii3 is reflected in the inverted image Irv. It is suppressed, visibility becomes good, and map Ii3 can be grasped correctly.

  In addition, according to the present embodiment, the background images Ib1, Ib2, Ib3, and Ib4 displayed as the background for the information display image Ii are displayed as real images in the reflection target area Arv. By doing so, even if the reflecting surface 80 reflects the light from the reflection target area Arv, the background images Ib1, Ib2, Ib3, and Ib4 are inverted and reflected in the inverted image Irv, so that the viewer can invert the information display. Is suppressed from being confused, and visibility is improved.

  Further, according to the present embodiment, the blurred image Ib4 created by blurring the information display image is displayed as the background image in the reflection target area Arv. Even if the blurred image Ib4 is reflected in the inverted image Irv, the content cannot be clearly seen and is not easily confused, so the visibility is improved. Furthermore, it is possible to give an impression that the information display image Ii is also displayed on the inverted image Irv, and the display feeling is increased.

  Further, according to the present embodiment, in the portion of the display surface portion 32 adjacent to the reflection target area Arv, the degree of blur increases so as to approach the blur degree in the blurred image Ib4 as the reflection target area Arv approaches. The image Iip is displayed. For example, in the case where the map Ii3 is adopted as the information display image Ii by such an interpolated image Iip, misperception such as a road that stops at the reflection target area Arv is suppressed, and visibility is reduced. It becomes good. Furthermore, continuity can be given to the display from the information display image Ii through the reflection target area Arv to the inverted image Irv, and the feeling of spreading of the display is enhanced.

  Further, according to the present embodiment, the reflection surface 80 is disposed adjacent to the reflection target region Arv, and the contour line OL in the background image Ib3 is the extending direction DE of the boundary portion 82 at the boundary portion 82 with the reflection surface 80. Intersects vertically. As a result, the contour line OL in the background image Ib3 and the contour line inverted in the inverted image Irv are connected without being bent, so that the display of the reflection target area Arv and the inverted image Irv is continuous, and the display is expanded. A feeling increases.

  Further, according to the present embodiment, the reflecting surface 80 is disposed adjacent to the reflection target area Arv, and the background images Ib1 and Ib2 are limited in direction dependency. Even if the background images Ib1 and Ib2 with limited direction dependency and the inverted images Irv of the background images Ib1 and Ib2 are viewed adjacent to each other, it is difficult to recognize that the background images Ib1 and Ib2 are inverted. In addition, the display of the reflection target area Arv and the inverted image Irv is continuous, and the feeling of expansion of the display is increased.

(Other embodiments)
Although one embodiment of the present invention has been described above, the present invention is not construed as being limited to the embodiment, and can be applied to various embodiments without departing from the gist of the present invention. it can.

  Specifically, as a first modification, instead of a tangent circumscribing the eyelips ELP, a region calculated by a light ray passing through an intermediate point between the left and right eye ranges may be employed as the reflection target region Arv. Moreover, the area | region obtained experimentally or empirically may be employ | adopted as reflection object area | region Arv.

  As a second modification, the information display image Ii may be displayed as a real image in the display hidden area Adh as long as it is outside the reflection target area Arv on the display surface 32a.

  As a third modification, the blurred image Ib4 as the background image may include a portion where the degree of blur changes in a gradation if it is difficult to determine the information of the original map Ii3. Further, the blurred image Ib4 may extend outside the reflection target area Arv.

  As the modification example 4, various forms can be adopted for the reflecting portion.

  Specifically, in FIG. 14, as an example of the fourth modification, the medium filling layer 74 is provided in the inner region AR so as to include the facing portion facing the holding frame 60 instead of the facing wall 72. The reflecting surface 80 in FIG. 14 is formed with smoothness as an interface with the gap 88 in the medium filling layer 74.

  As another example of the modified example 4, in FIG. 15, an interposed translucent plate 976 is provided between the image display panel 30 and the exposed translucent plate 40 in the internal region AR in place of the facing wall 72 and the medium filling layer 74. Is inserted. The reflective surface 80 in FIG. 15 is provided on the side end portion 976a of the interposed translucent plate 976 with smoothness as an interface with the gap 88.

  As another example of the modification 4, in FIG. 16, the reflecting surface 80 is provided by forming a reflecting film 972a such as a metal film or an optical multilayer film on the inner peripheral surface of the facing wall 72. .

  In FIG. 17 as another example of the modified example 4, in FIG. 17, the reflecting surface 80 includes a plurality of inclined reflecting portions 981a and reverse inclined portions 981b shown in an enlarged manner in FIG. 18, and is inclined reversely to the inclined reflecting portion 981a. An alternate arrangement structure is formed in which the portions 981b are alternately arranged. Each inclined reflecting portion 981a has a flat shape that is inclined toward the back side by forming an acute angle with the tangential direction of the display surface 32a. The inclined reflecting portion 981a has a smoothness so that the image light is specularly reflected. Each reverse inclined portion 981b is disposed between each inclined reflecting portion 981a, and is inclined toward the viewing side by forming an obtuse angle with the tangential direction of the display surface 32a. By such an inclined reflecting portion 981a, the reflection target area Arv can be narrowed. Therefore, it is possible to increase the degree of freedom in displaying the information display image Ii while improving the visibility of the display content.
