1. An image display device comprising:
a left-eye optical unit having a left-eye image region for displaying a left-eye image disposed on an incident side of the left-eye optical unit and having a left-eye exit pupil disposed outside an outermost lens on an exit side of the left-eye optical unit;
a right-eye optical unit having a right-eye image region for displaying a right-eye image disposed on an incident side of the right-eye optical unit and having a right-eye exit pupil disposed outside an outermost lens on an exit side of the right-eye optical unit;
a display section that causes a convergence angle to arise between two eyes when the left-eye image region is viewed through the left-eye optical unit and the right-eye image region is viewed through the right-eye optical unit, by presenting the left-eye image region such that its region center is disposed in a focal plane of the left-eye optical unit at a position away from an optical axis of the left-eye optical unit, and by presenting the right-eye image region such that its region center is disposed in a focal plane of the right-eye optical unit at a position away from an optical axis of the right-eye optical unit; and
a reflection section that reflects light emitted from the left-eye optical unit to form a left-eye pupil at a position having a conjugate relationship to the left-eye exit pupil, and reflects light emitted from the right-eye optical unit to form a right-eye pupil at a position having a conjugate relationship to the right-eye exit pupil.
