Abstract: A method of forming an electroluminescent device, comprising: forming a first charge carrier injecting layer (10) for injecting charge carriers of a first polarity; forming an organic charge carrier transport layer (11) over the first charge carrier injecting layer (10), the transport layer (11) having an electronic and/or optical property which varies across the thickness of the transport layer; forming an organic light emissive layer (12) over the transport layer (11); and forming a second charge carrier injecting layer (13) over the light emissive layer (12) for injecting charge carriers of a second polarity.
