Claim Text:
1. An organic electroluminescent element, comprising: an anode; a cathode; and a luminescent layer between the anode and the cathode, wherein at least the luminescent layer is formed according to a wet film formation method, and contains a charge-transporting material and a luminescent material, in which the charge-transporting material includes a hole-transporting material and an electron-transporting material each having a partial structure represented by formula (2-A) or formula (2-B), wherein the luminescent material includes three or more kinds of luminescent materials of phosphorescent organic metal complex compounds, and the combination of the basic skeleton of the ligands in the individual organic metal complex compounds have differs between the three or more kinds of the organic metal complex compounds, wherein the luminescent material has an emission spectrum having at least two kinds of emission maximums, and wherein the organic electroluminescent element comprises a hole injecting and transporting layer provided between the anode and the luminescent layer and adjacent to the luminescent layer: wherein, in formula (2-A): T represents an atom or an atomic group selected from —O—, —S—, —C(Ar Z wherein, in formula (2-B): T represents an atom or an atomic group selected from —O—, —S—, —C(Ar Z
