PURPOSE: An organic electroluminescent device utilizing filler for organic electroluminescent device and filler for organic electroluminescent devices are provided to improve endurance, lifetime of the organic electroluminescent device, and optical permeability of the light generated from the organic electroluminescent part. CONSTITUTION: Filler for organic electroluminescent devices is composed of organometallic compound in a liquid state which includes one or more chemical formulas from the following chemical formulas 1-4. In the chemical formulas, R and R1 - R4 indicate C1-C20 alkyl or C1-C20 acyl which includes C1-C20 alkyl group, C1-C20 cycloalkyl group, and heteroatom. M indicates trivalent to hexavalent metal elements, and n indicates integers of 10-100. The hetero atom is -NH-, -NHR'-, -S- or -O-. Here, R' indicates C1-C10 linear, branched, or cyclic alkyl group. |
