Patent ID: 7365367

Claim:
An organic electroluminescent device, comprising: a transparent substrate having at least first, second, third, fourth and fifth pixels defined thereon; a first longitudinal bank located between said first pixel and said second; a second longitudinal bank located between said second pixel and said third; an organic luminous polymer layer over said substrate and between said first longitudinal bank and said second longitudinal bank; a first transverse bank extending between said first longitudinal bank and said second longitudinal bank and located between said fourth pixel and said second pixel, said first transverse bank having a height less than a height of said first and second longitudinal banks; a second transverse bank extending between said first longitudinal bank and said second longitudinal bank and located between said second pixel and said fifth pixel, said second transverse bank having a height less than a height of said first and second longitudinal banks; and a plurality of first electrodes formed over said substrate, each of said first, second, third, fourth and fifth pixels being associated with a respective one of said first electrodes, wherein the plurality of first electrodes are divided along a longitudinal direction by the first transverse bank and second transverse bank, wherein the organic luminous polymer layer is separated from a neighboring organic luminous polymer layers by the first transverse bank and the second transverse bank, and wherein sidewalls of each of said first and second longitudinal banks extending from a top of said first and second longitudinal banks are sloped and continuously become wider toward said transparent substrate.
