Abstract
A display system includes a display panel configured to emit polarized light having a first polarization state and substantially distinct blue, green and red emission spectra having respective blue, green and red full widths at half maxima (FWHMs). The display system includes a reflective polarizer configured to reflect the polarized image light as a first reflected polarized image light. For substantially normally incident light and for the first polarization state, the reflective polarizer has a reflectance of greater than about 60% across each of the blue and red FWHMs, and a transmittance of at least about 50% for at least a first wavelength between the FWHMs of the blue and green emission spectra, and for at least a second wavelength between the FWHMs of the green and red emission spectra.
