Original Abstract Submitted
an optical system and a display apparatus are provided. the optical system includes: a lens component, a polarized reflection layer, a transflective film, and a phase retardation film; a distance between two intersection points where the first surface and the second surface intersect with the optical axis is a first distance, a distance between two intersection points where the third surface and the fourth surface intersect with the optical axis is a second distance, and a distance between two intersection points of the fifth surface and the sixth surface intersect with the optical axis is a third distance; a ratio of an absolute value of a curvature radius of the fourth surface to an absolute value of a curvature radius of the third surface is 0.8 to 1, the second distance is greater than the first distance, and the second distance is greater than the third distance.
