A polymer for an organic electroluminescent device applicable to a wet process while improving the luminous efficiency of the device, and an organic electroluminescent device obtained therefrom. The polymer for an organic electroluminescence device has a repeating unit represented by [- (Z) 1 - (A) m -] n in the repeating unit constituting the main chain. The organic electroluminescent device has an organic layer including a hole transporting layer and a light emitting layer between an anode and a cathode stacked on a substrate, and at least one of the organic layers includes the organic electroluminescent device polymer. In the above recurring units, Z is an N-indolocarbazolyl group, A is a repeating unit different from Z, l and m represent the existing molar ratio, l is 5 to 100 mol% and m is 0 to 95 mol% , and n is 2 to 10,000. |
