Abstract
An organic electroluminescent device includes a transparent substrate having at least first, second and third pixels defined thereon, a first longitudinal bank located between the first pixel and the second pixel, a second longitudinal bank located between the second pixel and the third pixel, and an organic luminous polymer layer over the substrate and between the first longitudinal bank and the second longitudinal bank. The device also includes a transverse bank extending between the first longitudinal bank and the second longitudinal bank. Sidewalls of the longitudinal banks and the transverse bank slope outwardly. The transverse bank has a height which is less than a height of the longitudinal banks. A method of forming the device utilizes nozzle coating or ink-jet coating, and a specially configured mask for producing the banks of differing heights.
