Display module having light-shielding portions with apertures having different shapes, virtual display apparatus, and manufacturing method for light-guiding optical device

A manufacturing method for a light-guiding optical device that guides image light emitted from a display element to form an exit pupil,

• the method comprising:
• a first forming step for forming a protective layer at a part on an optical surface of an optical member;
• a second forming step for forming a light-shielding portion at an area, in the optical surface of the optical member, where the protective layer is not formed, and
• a peeling-off step for peeling off the protective layer from the optical member where the light-shielding portion is formed, wherein
• the first forming step includes
• positioning a mask on the optical surface using a support member supporting the optical member, and then applying a protective-layer formation material onto the mask, and
• removing, after application of the protective-layer formation material, the mask from the optical surface to form the protective layer at a position corresponding to an aperture portion of the mask.

A manufacturing method for a light-guiding optical device that guides image light emitted from a display element to form an exit pupil,

• the method comprising:
• a covering step for disposing a cover member onto an optical surface of an optical member to cover a part of the optical surface;
• a light-shielding step for forming a light-shielding portion in a predetermined area, in the optical surface of the optical member, that is not covered by the cover member, and
• a removal step for removing the cover member from the optical member where the light-shielding portion is formed, wherein
• the covering step includes
• using, as the cover member, a member including a frame-shaped base portion, a cover portion located inside the base portion, the cover portion covering the optical surface, and a coupling portion coupling the base portion with the cover portion, in a state where a gap is created with respect to the optical surface, and
• the light-shielding step includes
• positioning the cover member on the optical surface using a support member supporting the optical member, and then applying a light-shielding material onto the predetermined area, of the cover member, that is not covered by the base portion and the cover portion to form the light-shielding portion.
