Beschreibung
Zusammenfassung:	Provided is a display method for displaying an image based on a color original image. The display method includes guiding an image light corresponding to the color original image to a display position by an optical system, and deflecting a traveling direction of the image light to an observer and performing display by a diffraction optical element. At the time of displaying the color original image, the image light entering the first diffraction optical element includes a light entering at a first angle and a light entering at a second angle that is larger than the first angle, a chromaticity range of the image of the color original image at a position corresponding to the light entering at the first angle is limited to be close to a chromaticity range of the light entering at the second angle.
