A metal complex compound having a special structure containing metals such
as iridium. An organic electroluminescence device which comprises at
least one organic thin film layer sandwiched between a pair of electrode
consisting of an anode and a cathode, wherein the organic thin film layer
comprises the above metal complex compound, which emits light by applying
an electric voltage between the pair of electrode. An organic EL device
employing the novel metal complex compound emits various phosphorous
lights including blue light having an enhanced current efficiency and
prolonged lifetime.
