ABSTRACT:
A process for manufacturing an organic electroluminescent device, including the steps of sequentially forming a hole transport layer, a bipolar transport layer at need, and an electron transport layer on a transparent electrode side of a transparent substrate having a transparent electrode. After a recombination region layer for electrons and holes of the transport layers is formed, three kinds of fluorescent pigment R, G and B are applied to an upper surface of the recombination region layer. Subsequently, the kinds of fluorescent pigment are heated to be diffused in the recombination layer so that the kinds of fluorescent pigment and the recombination layer constitute a luminescent layer. An organic electroluminescent device produced by this process is disclosed.
