Abstract: A polarization film and a display apparatus are provided. The polarization film includes first polarization layers and second polarization layers. The first polarization layers have a first refractive index with respect to a first polarization; and the second polarization layers have a second refractive index with respect to the first polarization and are arranged in each interval between the first polarization layers. The first polarization layers reflect light of the first polarization having color coordinates based on a thickness of the first polarization layers, at a boundary that touches the second polarization layers. The display apparatus includes a display panel and the polarization film.
