An image display apparatus (1C) of the present disclosure includes: an image light formation section (30) that outputs image light; a diffractive optical system that includes a first diffractive section (11) including at least one diffractive device and a second diffractive section (12) causing the image light to converge at a pupil position of a viewer, the first diffractive section (11) having a property of correcting a chromatic aberration that occurs at the second diffractive section (12); and a relay optical system (20) disposed closer to the image light formation section (30) than the second diffractive section (12) and relaying the image light to the second diffractive section (12) to correct the chromatic aberration that occurs at the second diffractive section (12).
