Abstract
A method of manufacturing an electroluminescent device which has an anode and a cathode and arranged between the anode and the cathode a light emissive layer, also includes an anode protection layer which protects the anode against the effects of converting a precursor polymer to a semiconductive conjugated polymer which constitutes the light emissive layer. This has been found to increase the brightness and half-life of devices.
