1. A transmissive display device, comprising:
- a cavity defined by a first fixed layer deposited on a substantially transparent substrate and a second movable layer connected to the substrate, the first and second layers being at least partially transparent;
a ring-shaped first electrode operatively connected to the first layer; and
a ring-shaped movable second electrode operatively connected to the second layer such that the second layer moves along with the second electrode;
wherein light incident to the display device is interferometrically modulated by the first and second layer, wherein the first and second layers collectively block out a substantial amount of visible light while the second layer is in a second position, and pass through light of a particular wavelength range while the second layer is in a first position.

Abstract
A transmissive backlit display is disclosed. In one aspect, the backlit display comprises a backlight and an array of transmissive interferometric modulators. Each interferometric modulator comprises a fixed and moving dielectric mirror stack. The interferometric modulators cause light within the desired wavelength range to be transmitted while reflecting at least a portion of the remaining light.
