Abstract
A head-up display device includes a first mirror having power, a second mirror having power, and a light-blocking member that is provided with an aperture. An image reflective surface has a convergence action. Display light emitted from an image display surface is reflected by the first mirror and the second mirror in this order, passes through the aperture, and reaches the image reflective surface. The image display surface is disposed on the same side as an observer and on a side opposite to the first mirror with respect to luminous flux that travels toward the aperture from the second mirror. The first mirror is a concave mirror. The shape of the cross-section of the second mirror taken along a front-rear direction is a convex shape.
