1. A pixel for a display device on a substrate, the pixel comprising:

  • a first interferometric modulator on the substrate, the first interferometric modulator having a first normal direction substantially perpendicular to the first interferometric modulator and a first angularly-dependent reflectivity function comprising a first reflectivity in a first direction and a second reflectivity in a second direction, the first reflectivity greater than the second reflectivity; and

    a second interferometric modulator on the substrate, the second interferometric modulator having a second normal direction substantially perpendicular to the second interferometric modulator and a second angularly-dependent reflectivity function comprising a third reflectivity in the second direction and a fourth reflectivity in the first direction, the third reflectivity greater than the fourth reflectivity.
