Title: Diode and process for making an organic light-emitting diode with a substrate planarisation layer

Abstract: An organic light-emitting diode (OLED) on a transparent substrate includes a microcavity formed between a reflecting cathode and semi-reflecting anode. The microcavity includes multiple organic layers with at least one light-emitting layer. The OLED is characterized by a transparent planarization layer between the substrate and an upper metallic layer forming the OLED semitransparent anode. A process for making such an OLED is also described.
