Abstract:
1. A method for manufacturing an organic light emitting device, the method comprising: providing a substrate comprising a first region, a second region, and a third region; forming a plurality of signal lines on the substrate, each signal line comprising an end portion; forming a plurality of output electrodes on the substrate; forming a passivation layer on the signal lines and the output electrodes; forming a first contact hole by etching the passivation layer, the first contact hole exposing the output electrode; depositing a conductor layer comprising at least two layers on the passivation layer, the at least two layers comprising a transflective electrode layer; forming a first photosensitive film pattern on the conductor layer corresponding to the first region, the second region, and the third region; etching the conductor layer using the first photosensitive film pattern as a mask to remove the conductor layer at a position corresponding to the end portion of the signal line and to form a pixel electrode at each position corresponding to the first region, the second region, and the third region; removing the first photosensitive film pattern; forming a second photosensitive film pattern exposing the pixel electrode at a position corresponding to one or two of the first region, the second region, and the third region, the second photosensitive film pattern covering the remaining pixel electrodes and exposing the passivation layer at a position corresponding to the end portion of the signal line; forming a second contact hole by etching the passivation layer using the second photosensitive film pattern as a mask, the second contact hole exposing the end portion of the signal line; depositing a conductive supplementary member layer on the second photosensitive film pattern; and patterning the conductive supplementary member layer to form a supplementary member on the pixel electrode exposed by the second photosensitive film pattern and to form a contact assistant contacting the end portion of the signal line.
