ABSTRACT:
A reflective-diffractive coating layer, situated at the interface between a substrate layer and an overcoat layer of the device, is divided into a set of small, slightly separated regions. This allows a direct bond of the overcoat layer to the substrate layer within the separation areas, which direct bond provides a more secure bond than that provided by a bond of the coating layer to the substrate and overcoat layers.
