Method for fabricating an organic electroluminescent device

摘要

An organic electroluminescent device and a method for fabricating the same are disclosed, the method including the steps of (1) forming a plurality of first electrode stripes (12) on a transparent substrate (11) at fixed intervals, (2) forming an array of partition walls (13) made of an electrically insulating material on the first electrode elements (12); having a trapezoidal structure with the lower side wider than the upper side, (3) forming an organic eletroluminescent multilayer (14), the second electrode (15), and the first protection layer (16) in succession on the entire surface including on top of the partition walls (13), (4) removing upper portions of films, unequivocally including the second electrode layer (15) on top of the partition walls (13), whereby electrically isolating any two adjacent pixels, and (5) forming the second protection layer (17) on top of the etched-out surface, whereby simplifying fabrication processes, improving product yield and reducing product cost.
