A beam-scan display apparatus (10) displays an image by scanning a beam on a retina of a user, the beam-scan display apparatus (10) includes a case (11) housing (i) a light source (101) emitting a beam for drawing each of pixels constituting the image, and (ii) a scan unit (103) two-dimensionally scanning the beam emitted from the light source (101). Further, the beam-scan apparatus includes a contact lens (12) having a deflection unit (104) deflecting, toward the retina of an eye of the user wearing the case (11), the beam scanned by the scan unit (103), wherein the contact lens (12) is separate from the case (11).
