Abstract: The present invention in one embodiment introduces a composite optical destructive layer (35) into the electroluminescent device which reduces the reflection of ambient light from the device. The composite optical destructive layer (35) is advantageously made of materials already found in the manufacturing process of the electroluminescent device (70) and also by manufacturing processes inherent in the manufacture of the device. More particularly, the composite optical destructive layer (35) is made from a variant of a parent material used to form one of the electrodes (12) of the electroluminescent device. The variant material differs from the parent material in that the variant material is oxygen deficient. This oxygen deficiency in the variant material causes the variant material to have a change in refractive index from that of the parent material.

Abstract: A light emissive device structure and a method for forming a light emissive device structure are provided. The structure comprises a transparent substrate; a transparent electrode formed on the transparent substrate; one or more light emitting layers formed on the first transparent electrode; a reflective electrode formed on the one or more light emitting layers; and a textured layer formed on the transparent substrate for enhancing light contrast of the device. Advantageously, the structure further comprises a gradient refractive index layer.
