Claim:
1. An organic light emitting device comprising: a substrate; a first electrode which is formed on the substrate by using a transparent resistance change material of which a resistance state is changed from a high resistance state into a low resistance state according to an applied electric field; an organic material layer which is formed on the first electrode and includes a light emitting layer; and a second electrode which is formed on the organic material layer; wherein the transparent resistance change material includes an insulating portion; wherein the transparent resistance change material of the first electrode has an inherent threshold voltage at which conducting filaments of the resistance change material are formed through the insulating portion of the resistance change material in the first electrode, and wherein the conducting filaments are formed by a process performed on the first electrode, the process comprising applying at least the threshold voltage to the first electrode to change the resistance state into the low resistance state.
