Patent ID: 8398242

Claim:
A display apparatus that displays an image on a retina of a user, said display apparatus comprising: an image output unit which includes a light source which emits a beam for drawing each of pixels constituting the image, and a scan unit configured to two-dimensionally scan the beam emitted from said light source; and a deflection unit configured to deflect, toward an eye of the user, the beam outputted by said image output unit, wherein said deflection unit includes a left-eye deflection unit configured to deflect, toward the user's left eye, the beam scanned by said scan unit, and a right-eye deflection unit configured to deflect, toward the user's right eye, the beam scanned by said scan unit, said left-eye deflection unit has a deflection characteristic of deflecting the beam such that the beam scanned on a left deflection area which is on the left of a virtual line and the beam scanned on a right deflection area which is on the right of the virtual line are bilaterally asymmetric with respect to the virtual line in incidence angle at which the beams enter the user's pupil, the virtual line extending through a center of the user's pupil and being perpendicular to said left-eye deflection unit, and said right-eye deflection unit has a deflection characteristic of deflecting the beam such that the beam scanned on a left deflection area which is on the left of a virtual line and the beam scanned on a right deflection area which is on the right of the virtual line are bilaterally asymmetric with respect to the virtual line in incidence angle at which the beams enter the user's pupil, the virtual line extending through the pupil center and being perpendicular to said right-eye deflection unit.
