Organic light emitting diode

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 third layer between the emission layer and the second electrode;
• a second layer between the emission layer and the third layer, wherein the second layer comprises at least one selected from the group consisting of LiF, NaF, KF, RbF, CsF, MgF2, CaF2, SrF2, BaF2, Liq, and Alq3;
• and
• a first layer comprising an organic material, wherein the first layer is between the emission layer and the second layer,
• wherein the first layer is in contact with the emission layer and in contact with the second layer, and
• wherein the third layer comprises a metal and a metal halide.
