Abstract
A vehicle has a display device which widens the field of view (visible area) reflected by a side mirror or a back mirror mounted on the vehicle. To enable a driver driving the vehicle to confirm safety even when it is difficult for the driver to visually recognize some of objects surrounding the vehicle, a liquid crystal display device or an EL display device is provided in the side mirror (door mirror), the back mirror (room mirror) or in an interior portion of the vehicle. A camera is mounted on the vehicle and an image from the camera is displayed on the display device. Further, information read from a sensor (distance measuring sensor) having the function of measuring the distance to another vehicle, and a sensor (impact sensor) having the function of sensing an externally applied impact force larger than a predetermined value is displayed on the display device.
