ABSTRACT:
A hole injection layer, a hole transport layer, a mixture luminescent layer, a hole blocking layer, an electron injection layer and a cathode are formed on an anode. The mixture luminescent layer includes TCTA as a luminescent substance, Ir(ppy) as a substance emitting light through a triplet excited state, and DCJTB as a luminescent substance emitting the light of a spectral component in the wavelength range of red.
