摘要:
An organic electroluminescent device (41) has a plurality of independently addressable electroluminescent elements (51A, B, C, D, E, F) and comprises a patterned first electrode layer comprising a plurality of first electrodes (43A, B, C) and a second electrode layer (26A, B, C, D); an organic, optionally patterned, electroluminescent layer (25) disposed between said first and said second electrode layer; an organic charge transport layer having charge transport areas (24A, B, C, D, E, F) disposed between the first electrode layer and the organic electroluminescent layer (25); and a relief pattern (27) extending between and along neighboring first electrodes. The relief pattern separates said charge transport areas along neighboring first electrodes which has the effect of disconnecting any current path between neighboring first electrodes via the charge transport layer. Thus, the EL device has a small leakage current and can be easily manufactured.
