Claim 2:
3. The display system of claim 1, wherein, for the first light incident at the first predetermined angle from about 30 degrees to about 50 degrees with respect to the normal and for the first polarization state, the reflective polarizer reflects the first light as a reflected light having an a* coordinate with a magnitude of less than about 6 and a b* coordinate with a magnitude of less than about 6 in CIELAB color space, and wherein, for the first polarization state and for a light incident on the reflective polarizer at an angle that deviates from the first predetermined angle by at most about 10 degrees, a change in each of the magnitudes of the a* and b* coordinates is from about 0.25 to about 5.
