In an on-board display apparatus, a transmission type display device is provided in front, displays a touch switch display when necessary, and operates as a touch panel. The transmission type display device can be turned to be transparent, and an image display device is provided rearward of the transparent portion. Since the display screen of the image display device toward the back, the visual range is long, and visibility can be improved. Since the display screen of the image display device and the display screen of the transmission type display device are not on the same plane, even if the touch switch display is touched by a finger, an image can be seen, and a pointer can be displayed on the display screen of the image display device in a position corresponding to the touched position.
