A head-up display device projects display light of an image on a projection member to virtually display a virtual image of the image. An illumination light source unit emits an illumination light. An image display panel causes the illumination light from the illumination light source unit to pass therethrough to be emitted as a display light from a display surface to display the image. A projection lens is located between the illumination light source unit and the image display panel and projects the illumination light from the illumination light source unit onto the image display panel. The image display panel is tilted so that a normal direction to the display surface intersects with an optical axis of the illumination light source unit. The projection lens is tilted so that a radial direction of the projection lens coincides with a tangential direction to the display surface.
