  "textContent": "A head-up display device includes a light emitting device array, an image formation unit, and an optical member. The light emitting device array includes multiple light emitting devices to emit illumination light and arrayed in a device array direction. The image formation unit forms an image according to illumination of an illumination light and emits the image as a display light. The optical member includes a diverging unit located in an optical path between the light emitting device array and the image formation unit and exerts a diverging action in the device array direction on the illumination light. The diverging unit includes one or more refractive surfaces to refract the illumination light while exerting a diverging action.",
