Disclosed is a rollable organic light emitting display system capable of protecting an organic light emitting display device from an external impact. The rollable organic light emitting display system has an organic light emitting diode layer between two substrates, wherein the two substrates are capable of being rolled or unrolled, includes a protection film covering a lateral surface of at least one of the substrates so as to prevent the lateral surface of the at least one substrate from being damaged by an external impact when the two substrates are unrolled and the lateral surface of the two substrates is exposed to the external.
