Abstract
An anamorphic optical system and a display apparatus including the same are disclosed. The anamorphic optical system includes an illumination system having astigmatism, and first and second correction lenses that are provided to have tangential power and sagittal power respectively and correct the astigmatism in the illumination system. The first and second correction lenses are provided in which a difference between a distance from the first correction lens to a tangential image formed by the first correction lens and a distance from the second correction lens to a sagittal image formed by the second correction lens corresponds to a distance between the first correction lens and the second correction lenses, and at least one of the first correction lens and the second correction lens has an asymmetric stop to form the tangential image and the sagittal image on the same surface.
