Abstract:
An organic light emitting display device includes a hole transport layer (HTL) having a first region and a second region, an emitting layer (EML) disposed on the hole transport layer in the first region, a hydrophobic pattern disposed on the hole transport layer in the second region and an electron transport layer (ETL) disposed on the hydrophobic pattern and the emitting layer.
