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.

Claim (Index 1):
A head-up display device that reflects display light of an image, which is displayed on an image display surface, toward an observer by an image reflective surface facing the observer to enlarge and display the image as a virtual image to the observer behind the image reflective surface, the head-up display device comprising:\n a first mirror having power; a second mirror having power; and a light-blocking member that is provided with an aperture, wherein the image reflective surface has a convergence action, display light emitted from the 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 the 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, and a shape of a cross-section of the second mirror taken along a front-rear direction is a convex shape in a case in which a direction of luminous flux traveling toward the first mirror from the image display surface is set to the front-rear direction on a reflective surface of the second mirror.
