Provided is a headup display (HUD) device. The HUD device is provided with: a light source unit (10) having a light emitting element (14); a condenser lens (20), which faces the light source unit, and collects light source light; a field lens (30), which further collects the light source light transmitted from the condenser lens side, and which projects the light at a predetermined angle; and an image forming element (40), which forms an image when the light source light transmitted from the field lens side is inputted thereto, and which projects light of an image toward the windshield side. The field lens has a composite surface (34) on the condenser lens side and/or image forming element side, said composite surface having a plurality of continuous optical surfaces. The capacitor lens has a diffusion unit (26) that diffuses the light source light. |
