ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE COMPRISING PROTECTIVE LAYER

摘要

PURPOSE: Provided is an organic electroluminescent device comprising a mechanically and chemically stable protective layer that serves as a reliable diffusion barrier to moisture. CONSTITUTION: An organic electroluminescent display device comprises the first electrode(8) of ITO with contact terminals(3), an electroluminescent layer(7) of PDOT, the second electroluminescent layer(6) of PPV and the second electrode of Al(5). The organic electroluminescent display device is additionally covered with a protective layer of amorphous carbon(4). The display device may be entirely covered with the protective layer of an amorphous carbon modification. Preferably, display device is provided on an optically transparent substrate(1) by means of an adhesive layer of SiO2(2).
