Method of fabricating array substrate for organic electroluminescent device and method of repairing the same

摘要

A method of fabricating an organic electroluminescent device (OELD) according to the present invention has steps of repairing a pixel region by irradiating a laser on a drain contact hole of a passivation layer in a pixel region in need of the repair; and disabling the connection between an organic electroluminescent diode and a drain electrode of a driving thin film transistor (TFT), where the pixel region of the OELD has i) the driving TFT comprising the drain electrode, ii) the passivation layer covering the driving TFT, while comprising the drain contact hole exposing the drain electrode of the driving TFT, and iii) the organic electroluminescent diode connected to the drain electrode of the driving TFT via the drain contact hole.
