Abstract:
A polymeric light emitting substance having a polystyrene reduced number-average molecular weight of from 103 to 108 wherein this light emitting substance has in the main chain or side chain a metal complex structure showing light emission from the triplet excited state, and the substance can form a light emitting layer by industrially simple application methods such as a spin coat method, inkjet method, printing method and the like.
