ABSTRACT:
An organic electroluminescent light emitting display device includes layers of organic electroluminescent material (24) (28) disposed between electrodes (12), (34) (38) for emitting an optical effect. The layers (24) (28) provide discrete electroluminescent pixels which are electrically isolated from one another by wall structures (16) (18) (20). The wall structures are preferably fabricated of dielectric materials. Further, the wall structures are characterized by the width in which a middle portion thereof is narrower than the top portion or the base portion.
