Abstract
A display device having an electroluminescent display element disposed on a surface of a substrate and a scratch resistant layer disposed over or surrounding the display element. The scratch resistant layer has a hardness level of at least 2.5 on Moh's hardness scale. Additionally, a moisture and oxygen barrier is disposed between the display element and the scratch resistant layer. An adhesive material can be used to secure the scratch-resistant layer to the display device and to provide a hermetic seal to the display element. Preferably, the thickness of the scratch-resistant layer is equal to or greater than 10 μm.
