To provide a car-mounted information display device capable of changing over between the image from a front side camera installed at the forefront of a vehicle and other driving information according to the vehicle speed without giving a sense of incompatibility to the driver.

The car-mounted information display device is structured so that changing-over from other driving information to the front side camera 2 to be conducted at a deceleration of the vehicle is performed at a timing V2a on the high speed side relative to the changeover timing V1a from the front side camera 2 to other driving information conducted at the time of starting the vehicle. This enables eliminating the sense of incompatibility, wherein the driver adapted to high-speed driving feels slow the changing-over of the display from the other driving information to the front side camera 2.
