A thiazole-based organic light emitting compound is provided to realize improved light emitting characteristics, driving voltage, electric power efficiency and lifespan of an organic light emitting device. A thiazole-based organic light emitting compound is represented by the following formula 1. In formula 1, A is a chemical bond or the formula (a); Ar1 is H, phenyl, 1-naphthyl or 2-naphthyl when m is 0, or Ar1 is a specific aryl group when m is 1 or 2; Ar2 is a specific divalent aryl group; Ar3 is another divalent specific aryl group; and R1 independently represents H, a halogen-substituted or non-substituted C1-C20 alkyl, C1-C20 alkylsilyl, C6-C20 arylsilyl or C6-C20 aryl group; and n is 1 or 2, wherein the aryl group of R1 is optionally further substituted with a C1-C20 alkyl group or halogen atom.
