Abstract
Disclosed is an organic light emitting diode device fabrication method that includes: preparing a substrate which is defined into a display area and a non-display area; forming a light emission portion, which includes a thin film transistor and an organic light emission layer in the display area, and a pad portion in a part of the non-display area; sequentially forming a sacrificial layer and an encapsulation passivation film throughout the display and non-display areas; and separating the sacrificial layer and the encapsulation passivation film from the pad portion through an irradiation of laser light.
