Abstract
A display panel and a display device having an emission control driver are discussed. The display device can include a display panel for displaying an image through sub pixels, and an emission control driver configured to supply a plurality of emission control signals to the sub pixels. The emission control driver can include a plurality of emission control stages configured to supply the plurality of emission control signals, respectively. Each emission control stage can include an output buffer including a first pull-up transistor configured to output a first high potential power supply voltage to an output line by a Q node, and a first pull-down transistor configured to output a first low potential power supply voltage to the output line by a QB node.
