Patent ID: 7109649

Claim:
An organic light emitting diode color display unit comprising: a substrate; a circuit layer formed on the substrate, wherein the circuit layer includes a plurality of active driving elements; an organic electroluminescent device formed on the circuit layer and comprising subpixels, wherein each active driving element is positioned in association with one of the subpixels to drive the associated subpixel, wherein the organic electroluminescent device includes first electrodes located on the circuit layer that completely cover the active driving elements, second electrodes spaced apart from the first electrodes, and an electroluminescent zone located between the first electrodes and the second electrodes, the electroluminescent zone comprising a thin film of an organic electroluminescent material; a transparent cover plate disposed opposite to the substrate; and color filter elements formed on the transparent cover plate, wherein said color filter elements are spaced away from the organic electroluminescent device and are positioned associated with the subpixels of the organic electroluminescent device, wherein light from the organic electroluminescent device is emitted from the transparent cover plate.
