Abstract
An object of the invention is to provide a polymer compound having a high hole transport capacity, excellent in electrochemical stability, and suitable to film formation according to a wet film formation method. Another object of the invention is to provide an organic electroluminescence element having a high current efficiency, a low drive voltage, and a long derive lifetime. The polymer compound has a crosslinking group bonding to the arylamine moiety in the repeating unit via at least one single bond therebetween.
