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 a compound A having a partial structure represented by the general formula (a) below and a reactive group, and is obtained by polymerizing the compound A through the reactive group. (In the formula, Ar1 and Ar2 respectively represent an aromatic ring.)

Disclosed is an organic electroluminescence element comprising an anode, a cathode and a plurality of organic compound layers between the anode and the cathode, provided that one of the organic compound layers is a light emitting layer containing a phosphorescence emitting compound,
wherein at least one of the organic compound layers contains a compound represented by Formula (1),
wherein, X represents O or S; Y
1
to Y
3
each represents a hydrogen atom, a substituent or a group represented by Formula (A) disclosed in the specification, provided that at least two of Y
1
to Y
3
are groups represented by Formula (A), not all of Y
1
to Y
