There are provided an organic electroluminescent (EL) element, which can realize the provision of a large screen by the formation of a film through coating in a simple and highly efficient manner, and a display panel using the same. The organic EL element comprises: a pair of opposed electrodes, a cathode and an anode; and an organic compound layer having a single-layer or multi-layer structure held between the pair of opposed electrodes, at least one layer constituting the organic compound layer being a layer containing at least one polymer comprising at least one monomer unit of a specific compound.
