Abstract:
A display module includes a display element, a light-guiding optical system forming an exit pupil, and an optical member including a light incidence surface and a light emission surface. The light-guiding optical system is an eccentric optical system, and includes first and second incidence areas on which the image light emitted from the light emission surface is incident. The optical member is disposed, correcting an inclination of the light emission surface with respect to the light-guiding optical system such that an variation amount in an incidence angle of the image light with respect to the first incidence area, before and after the light emission surface is inclined, is greater than an variation amount in an incidence angle of the image light with respect to the second incidence area.
