<P>PROBLEM TO BE SOLVED: To provide a full-color organic electroluminescent element improved in a life characteristic and efficiency without adding a new layer and a new process, in a phosphorescence emitting element using a phosphorescent substance for a luminescent substance. <P>SOLUTION: This full-color organic electroluminescent device comprises: a substrate 10; first electrodes 12 formed on the substrate; an organic luminescent layer formed on the first electrodes, and having a red luminescent layer 100, a green luminescent layer 200 and a blue luminescent layer 300', respectively patterned in a red pixel region, a green pixel region and a blue pixel region on a pixel region basis, and having the red and green luminescent layers formed of the phosphorescence emitting substance and the blue luminescent layer formed of a fluorescence emitting substance; a hole suppression layer 20 formed on the organic luminescent layer as a common layer; and a second electrode 24 formed on the hole suppression layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
