摘要： A headup display including a light emission-type display source, a concave mirror having an spherical reflecting surface and located so as to reflect light emitted from the display source, and a reflection-type hologram located so as to reflect the light reflected on the concave mirror toward an observer in a mobile unit. The concave mirror is configured so that its lateral focal length contributing to lateral enlargement of a displayed image is shorter than its longitudinal focal length contributing to longitudinal enlargement of the displayed image. The reflection-type hologram is configured so that its longitudinal focal length contributing to longitudinal enlargement of the displayed image is shorter than its lateral focal length contributing to lateral enlargement of the displayed image.
