Abstract

The present disclosure relates to a flexible display device including: a substrate over which a thin film transistor is disposed, an intermediate layer disposed to cover the thin film transistor, a first electrode located on the intermediate layer and connected to the thin film transistor, a bank located on the intermediate layer and the first electrode and defining a first region exposing a part of the intermediate layer, a second region exposing a part of the first electrode, and a third region excluding the first and second regions, a first structure located in the first region defined by the bank and tapered toward the substrate, an organic light emitting layer located on the first electrode exposed in the second region, and a second electrode disposed on the organic light emitting layer. Both lateral surfaces of an inverse-tapered structure are disposed to contact the bank, and as a result, corresponding adhesion can be improved, and peeling defects can be reduced or corrected.
