Patent ID: 7258589

Claim:
A method of forming an organic electroluminescent device having first and second substrates, comprising: forming array elements including a plurality of switching devices on the first substrate; forming a color changing medium on a rear surface of the second substrate, wherein the color changing medium has a black matrix that defines sub-pixel regions and has red, green, and blue color changing layers respectively corresponding to the sub-pixel regions; forming a planarizing layer on the color changing medium; forming a first electrode on a rear surface of the planarizing layer; forming electrode separators on the first electrode, wherein the electrode separators corresponds in position to the black matrix and form intervals corresponding to the sub-pixel regions; forming organic electroluminescent layers on the first electrode and into the intervals between the electrode separators; forming second electrodes respectively on rear surfaces of the organic electroluminescent layers that correspond to respective sub-pixel regions; forming a plurality of electrical connectors between the first and second substrates; and attaching the first and second substrates such that the electrical connectors connect an array elements on the first substrate to second electrodes on the second substrate, respectively.
