Abstract:
Provided are a polyvinyl pyrrole host material emitting highly efficient phosphorescence, a luminescent layer using the material, and an organic electroluminescent display device. The polyvinyl pyrrole host material shows highly efficient luminescence having improved energy transfer, and thus is useful for an organic electroluminescent display device and other various light emitting devices.
