Abstract
The present invention relates to an organic luminescence display panel and a method for fabricating the same which can improve a lifetime and luminous efficiency of an organic luminescence display device. The organic luminescence display panel includes a first electrode connected to a thin film transistor formed on a substrate, an organic layer having a light emission layer formed on the first electrode, a second electrode formed opposite to the first electrode with the organic layer disposed therebetween, a buffer layer formed between the first electrode and the light emission layer of a mixture of an inorganic material of an inorganic halide compound having fluorine and an organic material for interface stabilization between the first electrode and the organic layer, and an electron acceptor layer of an organic material having a strong electron accepting action group selected from cyanide group —CN, —NC, hydroxy group —OH, or halide group —I, Br, —F for making hole injection and transportation between the buffer layer and the light emission layer easy.
