Organic light emitting diodes with a complex multilayer structure have been successfully fabricated for bright light emission in the entire visible spectral region. The CIE coordinates of the blue, green, and red emitting electroluminescent devices are plotted in the chromaticity diagram. Double heterostructure organic LEDs with separate hole injection and transport layers allow to achieve low turn-on voltages of only about 4 V and a significantly increased quantum efficiency.
