Accordingly, since the image of the first display unit 10 is displayed outside the front window W, the driver M does not need to refocus in order to view the image by the first display unit 10. Further, the driver M can visually recognize the virtual image 10a of the first display unit 10 without diverting his line of sight during driving. Therefore, driving safety can be enhanced.
  • the information display device 1 includes an audio output unit 50 that outputs audio in conjunction with the display of the second display unit 20. Accordingly, since the second display unit 20 is displayed with voice, information can be provided reliably. Therefore, even if the driver M is not gazing at the virtual image 20a of the second display unit 20, the driver M can be attracted by voice. Accordingly, information can be provided to the driver M more reliably, and the ease of grasping the information can be further enhanced.
  • the information display device 1 includes a camera 30 that captures a passenger of the vehicle. Therefore, it is possible to detect whether the driver M is likely to fall asleep when the camera 30 photographs the driver's bag. Then, when the driver M is likely to fall asleep, alerting can be urged by the virtual image 20a (person image H or the like) of the second display unit 20. As a result, the driver M can be more reliably prevented from falling asleep. Further, the intention of the passenger can be recognized by the camera 30 shooting the gesture performed by the passenger. For example, the temperature adjustment of the air conditioner can be executed by the camera 30 shooting a gesture for adjusting the temperature inside the vehicle.
  • the information display device 1 includes a sound acquisition unit 40 that acquires sound inside the vehicle. Therefore, for example, when the voice acquisition unit 40 acquires the voice of the passenger's instruction, the passenger's instruction can be recognized by voice. For example, in the information display apparatus 1, information such as the position of the destination can be displayed on the first display unit 10 or the second display unit 20 by the voice acquisition unit 40 acquiring the voice of the destination instruction. .
