Abstract:
An electroluminescence device having a positive electrode, a negative electrode, a luminescent layer, and a buffer layer. The luminescent layer is disposed between the positive electrode and the negative electrode. The buffer layer is disposed between the luminescent layer and the negative electrode, where the buffer layer is a plasma polymerized film made of a gas material and having an average thickness of equal to or less than 30 Å.
