Abstract
A motor vehicle includes a windshield having a plastic layer sandwiched between two glass layers. The plastic layer has a partially reflective element therein. The partially reflective element passes a first portion of light received from a first direction and reflects a remainder of the light in a second direction. A projection arrangement projects a light field onto the partially reflective element such that a reflected portion of the light field is visible to a driver of the motor vehicle as a virtual image.
