Paragraph 0122-0123; 0134-0135; 0138-0139, (2020/02/28)
PURPOSE: An organic light emitting device is provided to have improved luminance efficiency, low voltage operation, and excellent color. CONSTITUTION: An organic luminescent diode includes a first electrode, a second electrode, and at least one organic layer. The organic layer includes an organic light emitting compound represented by chemical formula F. In chemical formula F, X is O, S, Se, or N; B is zero if X is S, Se, or O; each of A1, A2, A3, and B is selected from H, D, F, C1-40 alkyl group, C5-40 aryl group, C5-40 heteroaryl group, C5-40 aryloxy group, C1-40 alkyloxy group, C5-40 arylamino group, C5-40 diarylamino, C6-40 arylalkyl group, C5-40 ketone group, C5-40 arylketon, C3-40 cycloalkyl group, and C3-40 heterocycloalkyl group.
