PROBLEM TO BE SOLVED: To provide a head-up display device with increased merchantability.SOLUTION: A head-up display device (20) includes a light source (23) housed in a case (21), and a projection surface part (27) to which light (L1) from the light source (23) is projected. A light-shielding part (50) that can shield the light (L1) is disposed between the light source (23) and the projection surface part (27). The light-shielding part (50) has an opening (53a) that allows passage of a part of the light (L1). An edge of the opening (53a) is inclined such that an opening area gradually increases from the projection surface part (27) to the light source (23).SELECTED DRAWING: Figure 2 |
