1. An organic light emitting diode comprising:
a first electrode;
a second electrode overlapping the first electrode;
an emission layer between the first electrode and the second electrode;
a first layer between the emission layer and the second electrode;
a second layer between the first layer and the second electrode; and
a third layer between the second layer and the second electrode;
wherein the first layer is in contact with the emission layer and in contact with the second layer,
the second layer includes a dielectric material, the dielectric material having a band gap of 4 eV or more, and
the third layer includes a perovskite structure of a first compound comprising a metal and a metal halide.
