6. The vehicle display device according to claim 5 , wherein

the information acquisition unit acquires a current position of the vehicle and road information corresponding to the current position, as the information on the traveling vehicle, and

the switching unit switches from the first display mode to the second display mode when the information on the traveling vehicle acquired in the information acquisition unit indicates that the vehicle is traveling on an automobile-only road or a road with a large number of corners.

7. The vehicle display device according to claim 5 , wherein

the information acquisition unit acquires information on the traveling vehicle as the information on the traveling vehicle, and

the switching unit switches from the first display mode to the second display mode when the information on the traveling vehicle acquired in the information acquisition unit indicates that the vehicle is traveling on an automobile-only road and is in a cruise control operation.

8. The vehicle display device according to claim 1 , wherein

the information acquisition unit is a detection unit that detects whether a dashboard of the vehicle is illuminated by sunlight, and

the switching unit switches from the first display mode of the display panel to the second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring the visible area to be smaller than that of the first display mode, when the detection unit detects illumination by sunlight.

9. The vehicle display device according to claim 8 , wherein

the detection unit is located at a position where it is possible to detect illumination by sunlight from behind the vehicle.

10. The vehicle display device according to claim 1 , wherein

the information acquisition unit is a detection unit that detects a temperature of the display panel, and

the switching unit switches from the first display mode of the display panel to the second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring the visible area to be smaller than that of the first display mode, when the detection unit detects a temperature of a predetermined level of higher.

11. The vehicle display device according to claim 10 , wherein

the detection unit is located at a position where it is possible to detect a temperature in a dashboard of the vehicle in which the display panel is provided.

12. The vehicle display device according to claim 1 , wherein

the switching unit exposes the display panel to implement the first display mode and exposes a portion of the display panel such that a display area of the display panel is smaller than in the first display mode, thereby implementing the second display mode.
