Provided is a head-up display device with which it is possible to display an image easily recognized by a user. A display for a display mechanism in the head-up display device includes: a light source unit capable of generating light that is the origin of a scanning line; a scan unit for scanning light in a first direction and in a second direction using a first scan element and a second scan element, respectively; a processing unit for generating a first drive signal having a frequency that matches the resonance frequency of the first scan element; and a drive unit for executing a resonance mode that is based on the first drive signal. The processing unit generates a second drive signal having a variable display waveform that is dependent on the resonance frequency, fixed first non-display waveforms that are not dependent on the resonance frequency, and a variable second non-display waveform that is dependent on the resonance frequency. The drive unit drives the second scan element in a non-resonance mode that is based on the second drive signal.
