An organic light emitting device is provided to maximize current efficiency by controlling a charge mobility of a hole injection material and an electron transport material. A light emitting layer is positioned between a first electrode and a second electrode. The first hole injection layer is positioned between the first electrode and the light emitting layer. The first hole injection layer includes a metal fluoride and a first hole injection material. The mixing ratio of the metal fluoride and the first hole injection material is 1:1 or 3:1. The second hole injection layer is positioned between the first electrode and the light emitting layer. The second hole injection layer includes the molybdenum oxide and the second hole injection material. The mixing ratio of the molybdenum oxide and the second hole injection material is 1:1 or 3:1. The electron transport layer is positioned between the light emitting layer and the second electrode. The electron transport layer includes an electron transport material and the metal compound.
