Abstract: A display device includes a pixel. The pixel is disposed in a display area of a substrate, and is electrically connected to a first power line and a data line. An electrostatic discharge prevention circuit is disposed in a non-display area of the substrate, and is electrically connected between the data line and the first power line. The electrostatic discharge prevention circuit is electrically connected directly to the first power line, and is selectively electrically connected to the data line through a bridge line. The bridge line and the first power line are disposed in different layers with at least one insulating layer interposed therebetween.
