The organic electroluminescent device comprises an anode, a hole transport layer disposed on the anode, a light emitting layer disposed on the hole transport layer and generating light in response to hole-electron recombination; And an electron transport layer disposed on the light emitting layer. The device also includes a crystallization inhibiting material incorporated in the electron transport layer to prevent the electron transport layer from crystallizing during operation, and a cathode disposed on the electron transport layer. |
