Abstract
This disclosure relates to an organic electroluminescent display device and a method of sealing the same capable of reducing a manufacturing time and a complexity of manufacturing process. The organic electroluminescent display device comprises a first substrate including an active area and a bezel area outside the active area, the first substrate including an organic light emitting layer and a passivation film covering the organic light emitting layer thereon; a second substrate facing to the first substrate; and a filling layer in a space between the first substrate and the second substrate, wherein the filling layer includes; a first region having a first hardness, and spaced apart at a predetermined distance from the a passivation film to surround the protective layer in the bezel area; and a second region having a second hardness lower than the first hardness, and positioned inside the first region to be contacted with the first region.
