摘要
The present invention relates to an electro-optical device, wherein the device is a light source, for example an OLED. The OLED includes at least a substrate, a cathode, an anode, one or more organic light-emissive materials disposed between the cathode and anode, and a gradient refractive index film disposed on an external, light emitting surface of the device, for example on the substrate layer. Alternatively, the device may be constructed with the gradient refractive index film as the substrate, and/or the gradient refractive index film may be applied to more than one light-emitting surface of a device
