Abstract

A method of making an OLED by LPOVPD is provided which includes the step of forming an electron injection layer from an organic complex of a low work function metal e.g. lithium quinolate or a lithium Schiff base complex, the electron injection layer being deposited in a stream of inert carrier gas in the same reactor as other organic layers of the OLED e.g. a hole injection layer, a hole transport layer, an electroluminescent layer and an electron transport layer.
