Abstract： |
The invention relates to an organic electroluminescent part comprising an anode, a cathode and an organic functional layer arranged between the two electrodes; at least one of a hole infusion layer and a hole transmission layer contains matrix and mixed material; the mixed material is inorganic insulation material and chosen from the metal halide, metal oxide or metal carbonate. The invention overcomes the defect that the present OLED part is not very stable and the service life is short; with the structure of mixing insulation material in the part, the luminescent rate of part is effectively promoted and at the same time, the structure is beneficial to relieving the aging of working parts; the thermal stability of the part is properly increased and the service life of the part is greatly prolonged. |
