(First Embodiment) An embodiment in which the present invention is applied to a head-up display device for a vehicle will be described below with reference to the accompanying drawings.

  In FIG. 1, 10 is a windshield of a vehicle as an irradiation member, 20 is an instrument panel provided for disposing an instrument 30 such as a speedometer installed in front of the driver's seat of the vehicle, and a head-up display device 40 Is embedded in an opening 22 having a substantially rectangular shape formed in the substantially central portion of the upper wall 21 in the instrument panel 20 (see FIG. 2).

  As shown in FIG. 2, the head-up display device 40 is embedded (arranged) in the opening 22 of the instrument panel 20, and includes a display 41, a transmission / reflection member 42, a light control member 43, and a concave mirror (reflection). Body) 44 and a housing 45.

  The display 41 includes a hard circuit board 41a provided with a predetermined wiring pattern, a light source 41b mounted (arranged) on the wiring pattern of the circuit board 41a, and transmitted light by illumination light from the light source 41b. In this case, the circuit board 41a on which the light source 41b is mounted and the liquid crystal display panel 41c are arranged in an internal space of the housing 45 in FIG. Is inclined in the vicinity of the upper right of the space 45a.

  The light source 41b is a light-emitting body that includes a chip-type light-emitting diode that appropriately emits color and supplies illumination light to the liquid crystal display panel 41c.

  The liquid crystal display panel 41c is composed of, for example, a TFT (thin film transistor) type liquid crystal display element in which a polarizing film is provided on the front and back surfaces of a liquid crystal cell in which liquid crystal is sealed in a pair of translucent substrates, and transmits illumination light from the light source 41b. Thus, the display light L is arranged on the front side of the circuit board 41a.

  The liquid crystal display panel 41c includes an arithmetic circuit (not shown) for measuring the vehicle speed and the like based on an output signal from a vehicle speed sensor and the like provided in the vehicle, and a panel drive circuit (not shown) for driving the liquid crystal based on the calculation result. The measured value of the vehicle speed (vehicle speed) can be displayed as a numerical value. The display information displayed by the liquid crystal display panel 41c is not limited to the vehicle speed, and may be arbitrary, for example, engine speed, travel distance information, navigation information, and outside air temperature information.

  The transmission / reflection member 42 is composed of, for example, a half mirror in which a reflective film 42b made of a metal-based thin film or a light interference film is formed on one surface (a surface facing the liquid crystal display panel 41c) of a base material 42a made of a synthetic resin material, It arrange | positions in the state inclined between the liquid crystal display panel 41c and the light control member 43. FIG.

  The transmission / reflection member 42 is a non-formation region of an emission part (that is, near the upper right of the space part 45a), which will be described later, formed on the upper side of the housing 45 with the display light L that is the vehicle speed display light emitted from the liquid crystal display panel 41c. In FIG. 2, which is a diagonal direction, the light is transmitted as transmitted display light L1 to the concave mirror 44 disposed near the lower left of the space 45a), and the display light L which is vehicle speed display light emitted from the liquid crystal display panel 41c is transmitted. The reflected light is reflected as reflected display light L <b> 2 on the emission part side formed in the housing 45.

  In this case, the transmission / reflection member 42 is the front front of the driver seated in the driver's seat D of the vehicle, as shown in FIG. 3, with the reflected display light L2 emitted (irradiated) from the emitting portion. It is assumed that the windshield 10 is disposed at an inclined position at a position where it can irradiate a first area, which will be described later, of the windshield 10 that is the windshield 10 location.

  For example, although the detailed illustration is omitted, the light control member 43 is composed of a light control filter in which a light control layer including a large number of light control particles is sandwiched between a pair of resin substrates each having a transparent conductive film formed therein. The transmissive display light L1 that is disposed in an inclined state in the optical path of the transmissive display light L1 from the transmissive reflective member 42 to the concave mirror 44 (that is, between the transmissive reflective member 42 and the concave mirror 44) and transmits the transmissive reflective member 42. It has a function of adjusting the light transmittance.

  The light control member 43 shields the transmissive display light L1 incident on the light control member 43 because the light control particles included in the light control layer are not oriented when no voltage is applied between the transparent conductive films. In addition, when the voltage is applied between the transparent conductive films, the light adjusting particles are oriented, so that the transmissive display light L1 incident on the light adjusting member 43 can be transmitted to the concave mirror 44 side.

  That is, since the light transmission amount of the transmissive display light L1 transmitted to the concave mirror 44 side increases as the voltage value applied between the transparent conductive films gradually increases, the dimming member 43 transmits to the concave mirror 44 side. The light transmission amount of the transmissive display light L1 can be adjusted as appropriate.

  The concave mirror 44 is formed by depositing a reflective layer 44b on a resin substrate 44a made of polycarbonate having a concave surface. The concave mirror 44 is inclined so that the reflection layer 44 b faces the light control member 43, and transmits the transmissive display light L <b> 1 whose light transmission amount is adjusted through the light control member 43 after passing through the transmission reflection member 42. It consists of a reflector that reflects to the part.

  In this case, the concave mirror 44 transmits the transmissive display light L1 emitted (irradiated) from the emitting portion to the front of the front passenger of the passenger sitting in the passenger seat F of the vehicle as shown in FIG. It is assumed that the ten windshields 10 are inclined and arranged at positions that can be irradiated to second regions to be described later.

  The housing 45 is made of, for example, a black light-shielding synthetic resin material, is formed in a substantially box shape, and includes a display 41 having a liquid crystal display panel 41c and the like in a space portion 45a that is an internal space thereof, a transflective member 42, a light control The member 43 and the concave mirror 44 are held and accommodated, and the front display portion L1 reflects the transmissive display light L1 reflected by the concave mirror 44 and the reflective display light L2 reflected by the transmissive reflective member 42 on the front glass 10 side. A substantially rectangular opening window 45c is formed for passing through.

  In addition, an emission portion 46 is disposed on the front wall portion 45b of the housing 40 so as to close the opening window portion 45c. The emitting portion 46 is made of a translucent synthetic resin material (for example, acrylic resin), and includes the transmissive display light L1 that is the vehicle speed display light reflected by the concave mirror 44 and the vehicle speed display light reflected by the transmissive reflection member 42. It has a function as a light-transmitting member through which the reflected display light L2 is transmitted (passed).

  That is, in this case, the light transmittance is adjusted by the light adjusting member 43 while being transmitted through the transmissive reflecting member 42, and then the transmissive display light L 1 reflected by the concave mirror 44 and the reflected display light reflected by the transmissive reflecting member 42. L <b> 2 is configured to be emitted (irradiated) to the windshield 10 through the emission portion 46 formed in the housing 45.

It is inclined and arranged in the space 45a so as to irradiate the first region R1) of the windshield 10 on the right side of the windshield 10.

  Accordingly, the reflected display light L2 reflected by the transmissive reflecting member 42 and emitted from the emitting portion 46 corresponds to 10 windshields (that is, the driver's seat D) in front of the driver sitting on the driver's seat D. The first region R1) of the windshield 10 is irradiated. As a result, the driver sitting in the driver's seat D can visually recognize the first display image V1, which is the vehicle speed display image obtained by the irradiation, superimposed on the scenery (see FIG. 4).

  Further, the concave mirror 44 has ten windshields 10 in front of the front passenger of the passenger seated in the passenger seat F (that is, the windshield 10 in FIG. 3). The second region R2 of the windshield 10 that is a region on the left side of the windshield 10 that is different from the first region R1 is inclined to the space 45a.

  Accordingly, the transmissive display light L1, which is the vehicle speed display light that is transmitted through the transmissive reflecting member 42 and adjusted by the light adjusting member 43 and then reflected by the concave mirror 44 and emitted from the emitting portion 46, is an assistant. Irradiation is performed on ten windshields (that is, the second region R2 of the windshield 10 corresponding to the passenger seat F) in front of the passenger sitting in the seat F. As a result, the passenger sitting in the passenger seat F can visually recognize the second display image V2 that is the same as the first display image V1 superimposed on the scenery (see FIG. 4).

In the head-up display device 40 that performs display by irradiating the windshield 10 of the vehicle through the liquid crystal display panel, the display light L from the liquid crystal display panel 41c is transmitted as the transmissive display light L1 to the non-formation region of the emitting portion 46 A transmissive reflection member 42 that reflects the display light L from 41c as reflected display light L2 to the emitting portion 46, and a concave mirror 44 that reflects the transmissive display light L1 transmitted through the transmissive reflecting member 42 to the emitting portion 46; The reflected display light L2 is applied to the first region R1 of the windshield 10 corresponding to the driver's seat D of the vehicle through the emission part 46. Both transmission display light L1 is made is irradiated to the second region R2 of the windshield 10 corresponding to the front passenger's seat F of the vehicle through the exit section 46.

  Therefore, it is not necessary to install a head-up display device for each occupant when making the same display image visible to both the driver driving the vehicle and the passenger riding in the passenger seat of the vehicle, Conventionally, it is only necessary to use one display and one housing, which have been used two by one, so that the number of components can be reduced compared to the conventional one and cost increase can be suppressed.

  In addition, the driver can visually recognize the first display image V1 displayed in front of the driver's seat using the reflected display light L2 reflected by the transmissive reflecting member 42 and the transmissive display light L1 reflected by the concave mirror 44. Since the passenger can visually recognize the second display image V2 displayed in front of the front passenger seat, both the driver and the passenger can visually recognize the display image without moving the line of sight as much as possible. Is possible.

  Further, in the present embodiment, the light control member 43 for adjusting the light transmittance of the transmissive display light L1 is disposed in the optical path of the transmissive display light L1 from the transmissive reflection member 42 to the concave mirror 44.
