A head-up display projects an image onto an eye-box of an observer. The head-up display includes a plurality of light source elements, liquid crystal panel, first lens, viewpoint detector, and controller. The plurality of light source elements are arranged into an array shape to output light beams. Liquid crystal panel displays the image, and first lens deflects the light beams emitted from the plurality of light source elements such that an identical region in an incident plane of liquid crystal panel is illuminated with the light beams. Viewpoint detector detects a viewpoint position of the observer. Controller controls light intensity of the light source elements according to the viewpoint position detected by viewpoint detector.
