1. An organic light emitting device comprising:
a first electrode;
a second electrode provided to face the first electrode; and
an organic material layer having one or more layers provided between the first electrode and the second electrode,
wherein the organic material layer comprises a light emitting layer, and the light emitting layer comprises a compound of any one of Formulae 5 to 12 as a dopant of the light emitting layer, and a compound of Formula 1-A as a host:
  wherein in Formulae 5 to 12:

R4 and R5 are the same as or different from each other, and are each independently hydrogen, deuterium, a halogen group, a cyano group, a nitro group, a hydroxyl group, a carbonyl group, an ester group, an imide group, an amino group, a silyl group, a boron group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
n1 and n2 are each an integer from 0 to 4;
n3 to n5 are each an integer from 0 to 3; and
when n1 to n5 are each 2 or more, two or more substituents in the parenthesis are the same as or different from each other;

n6 to n13 and n22 to n29 are each an integer from 0 to 4, and when n6 to n13 and n22 to n29 are each 2 or more, two or more substituents in the parenthesis are the same as or different from each other;
 wherein in Formula 1-A:
Y1 is a substituted or unsubstituted naphthobenzofuran group, a substituted or unsubstituted thiophene group, or a substituted or unsubstituted indolocarbazole group;
Y2 and Y3 are the same as or different from each other, and are each independently hydrogen, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
L1 to L3 are the same as or different from each other, and are each independently a direct bond, a substituted or unsubstituted arylene group, or a substituted or unsubstituted heteroarylene group;
R101 is hydrogen, deuterium, a halogen group, a cyano group, a nitro group, a silyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted phosphine oxide group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; and
q1 is an integer from 0 to 7, and when q1 is 2 or more, two or more R101s are the same as or different from each other.
