1. An organic light emitting diode (OLED), comprising:
a first electrode;
a second electrode facing the first electrode;
a first emitting material layer including a first host, a second host and a blue dopant and positioned between the first and second electrodes;
a first electron blocking layer including an electron blocking material of a spirofluorene-substituted amine derivative and positioned between the first electrode and the first emitting material layer; and
a first hole blocking layer including a first hole blocking material of an azine derivative and positioned between the second electrode and the first emitting material layer,
wherein the first host is an anthracene derivative, and the second host is a deuterated anthracene derivative.
