PROBLEM TO BE SOLVED: To provide a wavelength selection element having excellent performance and to provide a display device using the wavelength selection element, that is bright and has excellent color reproducibility. SOLUTION: The wavelength selection element is provided with a first polarized light controlling element 12 to vary the polarization state of light in a first wavelength region, a second polarized light controlling element 13 to vary the polarization state of light in a second wavelength region different from the first wavelength region and a pair of polarized light selection elements 11, 14 placed opposite to each other via the first and second polarized light controlling elements and selectively transmitting or reflecting light with specified polarized light directions respectively. |
