An image display apparatus according to the present invention includes an image light generator (100) that emits image light, a first reflection element (11) that the image light from the image light generator (100) is to enter, the first reflection element (11) having a transmitting action and a reflecting action on the image light, a second reflection element (12) that reflects, toward the first reflection element (11), the image light that has entered via the first reflection element (11) and causes the image light to re-enter the first reflection element (11), the second reflection element (12) having a reflecting action on the image light, a light-condensing optical system (20) that converges, toward a position of a pupil of an observer, the image light that has re-entered the first reflection element (11), and a controller (40) that controls a placement angle of the first reflection element (11), the second reflection element (12), or both on the basis of the position of the pupil of the observer.
