Abstract
Provided are a polymer compound which has a pyrrole derivative compound and a phenoxazine derivative compound as a repeating unit, and an organic electroluminescent (EL) device using the same for forming a hole injection layer and/or a hole transport layer. The polymer compound according to the present invention has superior electric features and a high hole-transporting capability. Thus the organic EL device using the polymer compound for forming a hole injection layer and/or a hole transport layer has superior features such as low voltage and high efficiency compared to using conventional materials.
