Display module and display device

A display module comprising:

• an image light generation device configured to generate image light;
• a light-guiding member configured to guide the image light emitted from the image light generation device;
• a first reflection surface configured to reflect the image light that is emitted from the image light generation device, passes through the light-guiding member, and is incident;
• a first diffraction element including a first incident surface and configured to diffract and deflect the image light that is emitted from the image light generation device, passes through the light-guiding member, and enters through the first incident surface;
• and
• a second diffraction element including a second incident surface and configured to diffract and deflect the image light that is emitted from the first diffraction element, passes through the light-guiding member, and enters through the second incident surface, and to emit the image light from the light-guiding member, thereby forming an exit pupil, wherein
• the light-guiding member includes a first deflection surface, a second deflection surface, a second reflection surface, a third reflection surface, a fourth reflection surface, a third deflection surface, and an emission surface,
• the image light emitted from the image light generation device is sequentially incident on the first deflection surface, the second deflection surface, the second reflection surface, the third reflection surface, the fourth reflection surface, and the third deflection surface inside the light-guiding member,
• the first reflection surface is provided at one of the first deflection surface and the second deflection surface,
• the first diffraction element is provided at the other of the first deflection surface and the second deflection surface,
• the second diffraction element is provided at the third deflection surface, and
• a distance from a reference position where an optical axis of the exit pupil and the emission surface intersect to the second deflection surface is longer than a distance from the reference position to the first deflection surface and longer than a distance from the reference position to the second reflection surface.
