Abstract:
1. A method of manufacturing a display element, the method comprising: forming a microlens in a substrate having a first surface and a second surface, the first surface spaced from the second surface, the microlens disposed adjacent the first surface of the substrate, the microlens having a refractive index different from a refractive index of the substrate; and forming a light modulator over the first surface of the substrate, the light modulator disposed over the microlens, the light modulator comprising an optical cavity configured to be adjusted to interferometrically modulate light, wherein forming the light modulator includes forming an optical stack on the first surface of the substrate or on a spacer layer disposed between the first surface of the substrate and the light modulator, the optical stack being electrically conductive, partially transparent and partially reflective.
