An organic compound represented by general formula (1-1) or (1-2):

• wherein in general formulas (1-1) and (1-2), R1 to R3 are each independently selected from the group consisting of a deuterium atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted amino group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted heteroaryloxy group, a substituted or unsubstituted silyl group, and a cyano group;
• R4 is a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkoxy group;
• I and m are each an integer of 0 to 5, and n is an integer of 0 to 3;
• a plurality of R1's may be the same as or different from each other, a plurality of R2's may be the same as or different from each other, and a plurality of R3's may be the same as or different from each other;
• and D1 is represented by general formula (2):
• in general formula (2), R5 to R7 are each independently selected from the group consisting of a deuterium atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted amino group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted heteroaryloxy group, a substituted or unsubstituted silyl group, and a cyano group;
• o and q are each an integer of 0 to 4, and p is an integer of 0 to 2;
