Patent ID: 7839459

Claim:
A flat panel display device comprising: a plurality of data lines extending in a first direction and spaced apart from one another on a substrate; a plurality of power supply lines extending in the first direction and spaced apart from one another; a plurality of scan lines extending in a second direction perpendicular to the first direction to cross the data line and the power supply line, the scan line being spaced apart from one another; at least two thin film transistors each on the substrate and including a semiconductor layer, a gate insulation film, a gate electrode, a source electrode, and a drain electrode; at least one capacitor having a first electrode and a second electrode, the first electrode connected to the source electrode or the drain electrode of one of the thin film transistors; an organic layer comprising at least one light-emitting layer coupled to one of the thin film transistors; and an electrostatic discharge prevention unit positioned at a terminal portion of at least one of the plurality of scan lines, wherein the electrostatic discharge prevention unit comprises cusps that are in contact with each other.
