ABSTRACT:
A device is provided. The device has a first electrode comprising a reflective material, and a second electrode disposed over the first electrode, the second electrode comprising a transmissive material. An organic layer including an emissive material is disposed between the first electrode and the second electrode. A light modulating element is disposed over the second electrode. In one embodiment, the first electrode is the only significantly reflective layer in the device. In another embodiment, the first and second electrodes and the organic layer are fabricated over the light modulating element, and the second electrode is reflective, not the first electrode. Color filters may be used to achieve a full-color display. Organic light emitting devices may be used that emit a broad spectra of light, such as white light. Organic light emitting devices that emit a single color of light may be used. Different organic light emitting devices that emit different spectra of light may be used.
