Abstract
An embodiment for a pixel for a display device on a substrate is disclosed. The pixel includes a first interferometric modulator on the substrate. The first interferometric modulator has 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, with the first reflectivity being greater than the second reflectivity. The pixel also includes a second interferometric modulator on the substrate. The second interferometric modulator has 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, with the third reflectivity being greater than the fourth reflectivity.
