1. A composition for an organic optoelectronic device, the composition comprising
a first host compound represented by Chemical Formula 1; and
a second host compound represented by Chemical Formula 2:

OG Complex Work Unit Chemistry
wherein, in Chemical Formula 1,
X is O or S,
L1 is a single bond,
L2 and L3 are each independently a single bond, a para-phenylene group, or a biphenylene group,
X1 to X3 are independently N or CRa,
at least two of X1 to X3 are N,
R1 to R3 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C12 aryl group, or a combination thereof,
Ra is hydrogen, deuterium, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted dibenzothiophenyl group, or a combination thereof, and
Rb and Rc are independently a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted dibenzothiophenyl group, or a combination thereof,
at least one of Rb and Rc is a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted dibenzothiophenyl group, or a combination thereof,
wherein “substituted” of Chemical Formula 1 refers to replacement of at least one hydrogen by deuterium, a C6 to C30 aryl group, a dibenzofuranyl group, or a dibenzothiophenyl group;

OG Complex Work Unit Chemistry
wherein, in Chemical Formula 2,
Y1 and Y2 are independently a single bond, a substituted or unsubstituted C6 to C30 arylene group, a substituted or unsubstituted C2 to C30 heteroarylene group, or a combination thereof,
Z1 and Z2 are independently a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, or a combination thereof,
