ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

An organic light emitting display device can include a substrate; a first electrode and an auxiliary electrode disposed on the substrate; a bank pattern disposed on a part of an upper surface of the first electrode and the auxiliary electrode, in which the bank pattern is divided into a first area and a second area disposed under the first area; a barrier rib disposed on a part of the upper surface of the auxiliary electrode, in which the barrier rib is divided into a third area having a reverse-tapered shape and a fourth area disposed under the third area and having a tapered shape; an organic emission layer disposed on the substrate; and a second electrode disposed on the organic emission layer.
