Abstract
A head-up display device includes: a plurality of light sources arrayed in matrix in a Y-direction and a Z-direction; and a lens unit in which a convex lens portion for collecting radiant light radiated from the light sources is formed opposing each light source. The plurality of light sources are arranged at an interval A in a Z-direction and at an interval B, which is smaller than the interval A, in the Y-direction. The lens unit has a first connection portion and second connection portions formed at boundaries of the adjacent convex lens portions. The first connection portion extends in the Y-direction, and the second connection portions extend in the Z-direction. A width of a short direction of the first connection portion is smaller than a width of a short direction of the second connection portions
