    • An organic light emitting device is provided and suitable for being disposed on a substrate. The organic light emitting device includes a cathode layer, a buffer layer, a material layer, an organic light emitting layer and an anode layer. The cathode layer is disposed on the substrate. The buffer layer is disposed on and contacts the cathode layer, and the cathode layer is disposed between the substrate and the buffer layer. The material layer is disposed on and contacts the buffer layer, and the buffer layer is disposed between the cathode layer and the material layer, wherein a difference between a lowest unoccupied molecular orbital of the buffer layer and a highest occupied molecular orbital of the material layer is smaller than 2 eV. The organic light emitting layer is disposed on the material layer. The anode layer is disposed on the organic light emitting layer.
