description A head-up display device includes: a housing including an opening at a top; a cover closing the opening; a display element housed in the housing; a first optical element on an optical path of display light from the display element; and a second optical element disposed on a portion of the optical path of the display light after the first optical element, and reflecting the display light toward the opening. The cover has a downward convex shape and includes a curved surface portion descending from a front end portion toward a rear end portion of the cover. The first optical element converges the display light. Among the display light emitted from a first end portion of the display element closer to the first optical element, light incident on an upper end portion of the first optical element travels toward a point below an upper edge of the second optical element.
