ABSTRACT:
An Organic Light Emitting Diode (OLED) which is adapted to inhibit the formation and growth of non-emissive areas known as “dark spots.” The OLED comprises an anode disposed on a substrate, a cathode, an electroluminescent (EL) layer disposed between the anode and the cathode and a hole transport layer disposed between the anode and the EL layer. The OLED has one or more dielectric organic barrier layers disposed between one or more of the OLED's layers. These barrier layers are made from an organic polymer and are adapted to resist permeation by oxygen and moisture and to inhibit metal migration.
