Provided is a heads-up display device that stably achieves a low brightness display in which the display does not feel too bright in a dark environment at night, which further does not give a vehicle driver discomfort with continuous changes in brightness, and which has excellent white balance in the entire range of display brightness. A heads-up display device (1) is provided with an external light illuminance detection section (70) that detects the illuminance of external light and adjusts the display brightness (B) for display of images, which are displayed, on the basis of external light illuminance (P) measured by the external light illuminance detection section (70). The heads-up display device (1) is further provided with a display brightness adjusting means (81a) that adjusts the display brightness (B) of the display image to a low level when a display image is displayed in a low brightness region that is lower than a prescribed brightness by controlling the polarization angle of a polarized light control element (11) and adjusting the transmittance (Z) for laser light (R, G, B) in a polarized light section (14).
