Abstract
A display module includes an image light generation device configured to generate image light, a first reflection section configured to reflect the image light from the image light generation device, a first diffraction element configured to diffract the image light entering a first incident surface, a second reflection section configured to reflect the image light from the first diffraction element, and a second diffraction element configured to diffract the image light entering a second incident surface, thereby forming an exit pupil. When viewed from a normal line direction of a virtual plane including a normal line of the first incident surface and a normal line of the second incident surface, an optical axis of the image light from the image light generation device toward the first reflection section and an optical axis of the image light from the first diffraction element toward the second reflection section intersect each other.
