Abstract:
A method of fabricating an electroluminescent device for displaying an image to a viewer in front of said electroluminescent device, comprising the steps of:depositing an anode layer onto a substrate; depositing an organic electroluminescent layer onto said anode layer, said electroluminescent layer having a first energy characteristic associated with an anode side, and a second energy characteristic associated with a cathode side; depositing an optical interference member onto said electroluminescent layer, said optical interference member reducing the reflectance of ambient light towards said viewer, said optical interference member having a thickness which causes destructive optical interference of ambient light, said optical interference member having a work function substantially equal to said second energy characteristic such that the difference between the second energy characteristic and the optical interference member work function is from about 0.0 electron-volts to about 1.5 electron-volts, said optical interference member comprising (i) a semi-absorbent layer comprising magnesium silver, and (ii) a transparent layer comprising indium tin oxide; depositing a cathode layer onto said optical interference member; and applying a sealing layer onto said cathode layer.
