An image display apparatus has one display screen configured to display images corresponding to a plurality of observers. The image display apparatus comprises an illumination means for emitting a first light flux and a second light flux in at least two different directions in a time sharing manner, and a transmissive display element configured to display in a time sharing manner a first image using the first light flux emitted from the illumination means as illumination light and a second image using the second light flux as illumination light, and the illumination means includes a first light source 20 which emits the first light flux, a second light source 25 which emits the second light flux, a first light guiding plate 21 which projects the first light flux emitted from the first light source 20 only in a direction to a first observer, and a second light guiding plate 22 which projects the second light flux emitted from the second light source 25 only in a direction to a second observer.
