| 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 composition for a light emitting device, in which a host material and a guest material are blended, wherein the host material contains an aromatic compound having a condensed ring skeleton in which only three or more benzene rings are condensed, and the guest material is A total amount of sodium atoms contained in the host material and sodium atoms contained in the guest material is 1 mass ppb or more 385 or more including an aromatic compound containing only hydrogen atoms and carbon atoms. A composition for a light emitting device having a mass of ppb or less. [Selection diagram] None |
