The image display apparatus includes first and second display elements respectively displaying first and second original images, and an optical system presenting an enlarged combined image of the first and second original images with first and second light fluxes from the first and second display elements. The optical system includes at least one reflective surface. When a cross-section of the optical system on which optical paths of the first and second light fluxes are turned by reflections at the reflective surface is defined as a decentering cross-section, the first and second original images correspond to different view angles in the decentering cross-section. Light flux components respectively included in the first and second light fluxes and introduced to a same image point in the enlarged combined image are overlapped with each other on an exit pupil plane.
