A first polarizer transmits incident light of a first polarized direction and absorbs incident light of a polarized direction different from the first polarized direction. A birefringent film layer rotates a polarized direction of light of a predetermined wavelength to a second polarized direction different from the first polarized direction in a light transmitted through the first polarizer. A second polarizer transmits light of the first polarized direction and reflects a light of the second polarized direction in a light transmitted through the birefringent film layer. A substrate absorbs light transmitted through the second polarizer.
