1. An organic light emitting device comprising:
an anode;
a cathode provided to face the anode; and
an organic material layer comprising a light emitting layer provided between the anode and the cathode,
wherein the light emitting layer, one or more layers of the organic material layer provided between the anode and the light emitting layer, and one or more layers of the organic material layer provided between the cathode and the light emitting layer each comprise one or more compounds each composed of sp3 carbon as a center,
the light emitting layer comprises a host comprising one or more anthracene-based compounds, and
among organic materials included in the organic material layer, a band gap energy (Ebg) of each of the organic materials except for a dopant compound is 3 eV or more.
