1. A display comprising:
- at least one optical display element configured to reflect incident light, the at least one optical display element having an optical response that depends at least in part on angle of view and wavelength of the incident light; and
a diffuser having an optical response that corresponds to the optical response of the optical display element to reduce color shift at different angles of view.

10. A display comprising:
-
at least one optical display element having a spectral responsivity that varies with angle of view, θ
, such that color varies with angle of view; anda non-lambertian diffuser having an optical response that varies with angle of view, said diffuser reducing variation of color with angle of view. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
