Abstract:
An organic electroluminescent device and a method of preparing the same are provided. The organic electroluminescent device includes a sealing layer which is formed on a sealing substrate, and which includes a cohesion layer, a transparent polymer layer, and a transparent moisture absorption layer. Since the transparent moisture absorption layer of the organic electroluminescent device is provided to a sealing substrate using an attaching method, the organic electroluminescent device has an improved life span property due to a firm sealed structure and better light extraction efficiency due to the transparent moisture absorption layer below the sealing substrate.

The organic electroluminescent device may be used as a front emission type, a rear emission type, or a both-direction emission type display.
Abstract:
An organic electroluminescent (EL) display device and a method of manufacturing the same are provided. The organic electroluminescent display device includes a rear substrate, a organic EL portion formed on one surface of the rear substrate with a first electrode, an organic layer and a second electrode sequentially laminated. The front substrate is coupled to the rear substrate to seal an internal space in which the organic EL portion is accommodated, for isolating the organic EL portion from the outside. The front substrate further has a transparent moisture-absorbing layer coated on its internal surface.
