Abstract
A head-up display causes light modulated by an optical modulation element to form, via a projection lens, an intermediate image on a screen, and then causes the intermediate image to reflect, via a mirror, on a windshield to allow a user to view a virtual image. A normal line of the screen is inclined with respect to an optical axis of the projection lens. An emission surface of the optical modulation element is inclined with respect to the screen and a principal plane of the projection lens so as to satisfy a Scheimpflug condition.
