Abstract:
Disclosed is an organic electroluminescent device having high external quantum
efficiency and long emission life. Also disclosed are an illuminating device
and a display, each comprising such an organic electroluminescent device. The
organic electroluminescent device is characterized by comprising at least
an anode and a cathode on a supporting substrate, while having at least one light-emitting
layer between the anode and the cathode. The organic electroluminescent device
is also characterized by containing a polymer which at least partially contains
