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.
