An organic electroluminescence (EL) device capable of digital driving, and
a method for manufacturing the same are disclosed herein. The organic EL
device comprises a substrate, an anode formed on the substrate, an
organic EL layer formed on the anode and constructed as a multilayer
structure including a hole injection layer and a hole transport layer, a
cathode formed on the organic EL layer, and an interface deterioration
preventing layer formed between the anode and the organic EL layer.
