| titleOfInvention | Light emitting device composition and light emitting device containing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a composition useful for manufacturing a light emitting device in which long-term deterioration is suppressed, and a light emitting device formed by using the composition. A guest material composition comprising a host material and a guest material, wherein the host material includes an aromatic compound having a condensed ring skeleton in which only three or more benzene rings are condensed. Includes an aromatic amine compound, and the total amount of iron atoms contained in the host material and iron atoms contained in the guest material is 40 mass ppb or more and 1740 mass ppb with respect to the total mass of the host material and the guest material. The following is a composition for a light emitting device. [Selection diagram] None |
