Abstract
Provided is a display panel including a substrate, a plurality of pixels arranged on a display area of the substrate, a plurality of dummy pixels arranged on a non-display area of the substrate and emitting no light, and a plurality of signal lines configured to electrically connect the plurality of pixels to the plurality of dummy pixels, wherein some of the plurality of dummy pixels are arranged between a first region and a second region of the substrate. Accordingly, when static electricity is generated around the first region and/or the second region, the dummy pixels serves as a buffer to prevent a large voltage transmitted to the pixels to protect the display device.
