A glare mitigation module for a head-up display system is configured to transmit display light emitted from an illumination device therethrough. The glare mitigation module comprises an input surface through which the display light from the illumination device enters the glare mitigation module and an output surface through which the display light from the illumination device exits the glare mitigation module in a display direction. The glare mitigation module further comprises a diffractive optical element comprising a plurality of layers stacked successively between the input and output surfaces, with the plurality of layers arranged to transmit the display light of the illumination device therethrough and to diffract an external light that enters the glare mitigation module through the output surface. The diffractive optical element is arranged to diffract the external light in a diffracted direction away from eyes of an occupant.
