Head-up display device

A head-up display device that projects two display images on a windshield of a mobile unit to display virtual images of the two display images at different positions to be visible for an occupant of the mobile unit, comprising:

• a first display surface configured to emit a near display image to display a near virtual image at a position near the windshield, of the two display images;
• a second display surface configured to emit a far display image to display a far virtual image at a position farther from the windshield than the near virtual image, of the two display images;
• a magnification optical element configured to magnify light emitted from the first display surface and the second display surface and to reflect the light toward the windshield to form the near virtual image and the far virtual image respectively magnified from the near display image and the far display image;
• and
• a correction optical element provided in an optical path of the light of the far display image, wherein
• the correction optical element is configured to correct an optical influence, together with the magnification optical element, to be generated in the far virtual image by a reflection on the windshield,
• the correction optical element has a reflective surface to reflect the light of the far display image emitted from the second display surface toward the magnification optical element, and
• the correction optical element, in a state of being mounted on the mobile unit, is located opposite to the windshield with respect to the first display surface.
