ABSTRACT:
An improvement in a light emitting device having an image display array consisting of a plurality of light emitting pixels arranged in intersecting columns and rows. The pixels are each located on a common electrically insulative light transmissive support with pixels in the same column including a common light transmissive first electrode element located on the support. An organic electroluminescent medium overlies the first electrode elements. The pixels of each row include a common second electrode element located on the organic electroluminescent medium. The light emitting device is fabricated by providing the support with the first electrode elements positioned in laterally spaced columns thereon to form a supporting surface, depositing the organic electroluminescent medium on the supporting surface, and forming the second electrode elements on the surface of the organic electroluminescent medium.
