Abstract
Disclosed is an organic light emitting display device that includes a foreign matter compensation layer on an inorganic layer. A passivation layer and a second inorganic layer are in direct contact with each other at the edge of the substrate. Accordingly, the number of interfaces between the inorganic layers is decreased. Thus, even if the organic light emitting display device is bent, a moisture permeation path, which may be unexpectedly formed, can be minimized.
Claims10
An organic light emitting display device comprising:
- a flexible substrate having an emission area and an edge sealed area;
- a thin-film transistor on the flexible substrate in the emission area;
- a passivation layer configured to cover the flexible substrate and the thin-film transistor;
- an organic light emitting element configured to be connected to the thin-film transistor on the passivation layer;
- a first inorganic layer formed of a different material from the passivation layer and configured to seal the organic light emitting element such that the first inorganic layer covers the organic light emitting element at the emission area, and an extended portion of the first inorganic layer is in contact with the passivation layer at an outer portion of the emission area;
- a foreign matter compensation layer on the first inorganic layer;
- and
- a second inorganic layer formed of a same material as the passivation layer configured to cover the foreign matter compensation layer, and configured to be sealed at the edge sealed area such that the second inorganic layer is in contact with the passivation layer.
