Patent ID: 8665191

Claim:
An organic light emitting display comprising: a display unit comprising a plurality of pixels positioned at crossing regions between a plurality of scan lines and a plurality of data lines; a scan driver for supplying scan signals to the plurality of scan lines; a data driver for supplying data signals to the plurality of data lines; a pad unit comprising a plurality of pads for transmitting driving power and driving signals to at least one of the display unit, the scan driver, or the data driver; a protective circuit unit coupled between at least one of the display unit, the scan driver or the data driver, and the pad unit; a driving power line for transmitting the driving power from the pad unit to the display unit, the scan driver, or the data driver via the protective circuit; and a driving signal line for transmitting one of the driving signals from the pad unit to the display unit, the scan driver, or the data driver via the protective circuit, wherein the protective circuit unit comprises at least one transistor comprising a gate electrode, a semiconductor layer, an insulating layer on the semiconductor layer, and a conductive layer on the insulating layer, wherein one region of the conductive layer that overlaps the semiconductor layer is physically disconnected to create two adjacent ends of the conductive layer, the two adjacent ends coupled to each other through the semiconductor layer, the two adjacent ends having first edges that face each other, the driving power line comprising the gate electrode and one of the two adjacent ends, the driving signal line comprising another of the two adjacent ends, and wherein the first edges of the disconnected conductive layer have recesses and protrusions.
