摘要： A light emitting device having excellent external quantum efficiency contains an anode, a cathode, and two organic layers disposed therebetween. One layer contains a phosphorescent transition metal complex and a low molecular weight compound containing no transition metal, and the second layer contains a crosslinked body of a polymer compound (having an energy level of the lowest triplet excited state of 2.30 eV or more) containing a constitutional unit having a crosslinking group. The low molecular weight compound has formula (T-1) and the absolute value of the difference between the energy levels of the lowest triplet excited state and the lowest singlet excited state is less than 0.25 eV. nT1 represents an integer of 0 to 5, nT2 represents an integer of 1 to 10, ArT1 represents a substituted amino group or a monovalent hetero ring group, LT1 represents an alkylene group, and ArT2 represents a hetero ring group.
