Organic Light Emitting Diode (OLED) devices have recently gained attention as one of the promising next-generation display devices because of their several excellent features compared with the others. The OLED device technology, which has a relatively short history, is still being developed and has many problems to be solved. Therefore, it is necessary to analyze the mechanism of deterioration phenomena of OLED in order to improve its performance and durability. However, the analysis of OLED devices has not progressed much yet because OLED has very weak and sensitive characteristics. Especially, research and analysis of the interface phenomena have not been sufficiently conducted. In this article, deterioration phenomena regarding interfaces of OLED devices will be introduced. Especially, the relation of operating lifetime and interfaces between organic material and anode or cathode, and the mechanism of dark spots generated and grow in OLED device are described.
