Abstract: Disclosed is an organic light emitting display device. The organic light emitting display device includes a first emission part between a first electrode and a second electrode and a second emission part on the first emission part. The first emission part includes a first hole transport layer and a first emission layer, and the second emission part includes a second hole transport layer and a second emission layer. A thickness of the second hole transport layer is greater than a thickness of the first hole transport layer.

Abstract: A display apparatus according to an embodiment can include a first electrode, a plurality of organic layers, a second electrode, and a metal layer disposed on a particular organic layer among the plurality of organic layers. The metal layer is configured to protect the particular organic layer from being damaged when it is exposed to a non-vacuum environment at least once during processes of stacking the organic layers on the first electrode and the second electrode on the organic layers in a vacuum environment, thereby suppressing a rise in the driving voltage of the display apparatus. Accordingly, the problems that the driving voltage of the display apparatus increases and the lifespan is shortened can be addressed.
