Abstract: A windshield (1) for motor vehicles provided with a reflecting arrangement (6) for making optical information or signals visible to the driver of the vehicle; said information or signals being made recognizable in the same field of view as is suitable for the observation of traffic and the road ahead by said driver. According to the invention, the reflecting arrangement (6) is a hologram with the characteristic of a mirror. The angle of reflection .alpha. of the holographic mirror is different from the angle of reflection .beta. of the surface of the glass upon which said hologram is mounted. As a result the rays R' reflected from the surface of the glass do not reach the eye (8) of the observer, whereas the rays R reflected from the holographic mirror do.
