A virtual image display device includes an imaging light generation device that generates an imaging light, a first reflection type diffraction element that diffracts the imaging light from the imaging light generation device, a second reflection type diffraction element diffracts the imaging light from the first reflection type diffraction element so that the imaging light reflected by the first reflection type diffraction element is compensated for wavelength distribution, and a concave transmission mirror that has a concave shape and includes a partial reflection film reflecting a part of the imaging light and transmitting other part of the imaging light. In the second reflection type diffraction element diffracts the imaging light toward the mirror and transmits the part of the imaging light reflected by the mirror.
