    Abstract: The present invention relates to an organic thin-film light emitting device containing an organic compound represented by formula (1) and a donor compound. the light emitting device ca achieve both of the low-voltage driving operation and high luminance efficiency. €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Y(5A 1 -Ar) n 1 €ƒ€ƒ€ƒ€ƒ€ƒ (1) (Y represents either substituted or unsubstituted pyrene, or substituted or unsubstituted anthracene. A 1 is selected from the group consisting of a single bond, an arylene group, and a hetero arylene group. Ar is selected from the group consisting of a carbazolyl group, a dibenzofuranyl group, and a dibenzothiophenyl group. These groups may be substituted or unsubstituted, and n 1 is an integer of 1 to 3.)
