Organic electroluminescent multicolor image display device

A multicolor image display device comprised of an array consisting of

• a plurality of light emitting pixels arranged in two intersecting sets of parallel files, the pixels in a first set of parallel files forming columns and the pixels in a second set of parallel files forming rows on a common electrically insulative light transmissive support,
• the pixels in each file of one of said first set or said second set of parallel files containing and being joined by a common light transmissive first electrode means overlying said support,
• the first electrode means in adjacent files being laterally spaced on said support,
• an organic electroluminescent medium overlying the first electrode means and said support,
• the pixels in each file of the other of said first set or said second set of parallel files containing and being joined by a common second electrode means overlying said organic electroluminescent medium, and
• the second electrode means in adjacent files being laterally spaced on said organic electroluminescent medium,
• characterized in that the light emitting device is capable of producing full color image display,
• each pixel in said first set of parallel files of pixels is divided into three sub-pixels,
• said organic electroluminescent medium in each pixel in said first set forms three areas, each within one sub-pixel of each pixel in said first set and each capable of emitting light of a different primary hue,
• a set of walls is positioned between adjacent files of pixels and between one of the sub-pixels in each of the pixels in each of the files and the two remaining sub-pixels in each of the pixels in each of the files, the walls each being of a height exceeding the thickness of the organic electroluminescent medium and capable of shadowing adjacent sub-pixels, and
• each electrode means of one of said first set or said second set of parallel files being divided into three laterally spaced electrode elements each joining one sub-pixels of each of the pixels in said first set or said second set of parallel files.
