Abstract: The invention relates to a display device (1) comprising: - a light source (20) designed to generate a source light beam (S) extending over a predetermined wavelength range; - a diffractive optical element (40), the operating range of which is adapted to said wavelength range and which is arranged to receive said source light beam (S) and to transmit an image light beam (I); and - a dichroic filter (50) placed in the path of said image light beam and the passband of which at least partially covers said wavelength range so as to at least partially transmit said image light beam.
