Abstract
A display panel and a display device are provided. The display panel includes a substrate, a thin film transistor layer, an organic light emitting diode (OLED) layer, a thin film encapsulation layer, a first common electrode layer, a cover plate, and conductive lines. An area without touch function of the display panel is eliminated by disposing the conductive lines at a side of the first common electrode plate, placing the conductive lines and the first common electrode plate respectively on two film layers, and electrically connecting with each other via through holes of an insulation layer.
