A display panel and a display device including the same are discussed. The display panel includes a display area in which a plurality of data lines, a plurality of gate lines, and a plurality of sub-pixels are disposed, and a gate driver configured to supply gate signals to the gate lines. The display area includes a high-speed driving area, and a low-speed driving area driven at a frequency lower than that of the high-speed driving area. One cycle of a clock signal input to the gate driver includes a high interval with a gate high voltage and a low interval with a gate low voltage. A high interval of the clock signal is longer than a high interval of the high-speed driving area at a scanning time point of a first pixel line from which scanning of the low-speed driving area is started.
