摘要： A display panel and a display device having an emission control driver are discussed. The display device can include a display panel to display an image through sub pixels, a scan driver to supply a second scan signal to each of second gate lines, and an emission control driver to supply an emission control signal to each of third gate lines and supply a first scan signal to each of first gate lines. Each emission control stage of the emission control driver can include an output buffer. The output buffer can output an emission control signal to an output line and output a first scan signal to a scan output line under control of a first control node, and output a high potential power supply voltage to the output line and output a low potential power supply voltage to the scan output line under control of a second control node.
