1. A display device comprising:
a plurality of pixels connected to a plurality of first scan lines, a plurality of second scan lines, and a plurality of data lines, wherein the pixels are arranged in a plurality of rows;
a plurality of first stages connected to the first scan lines;
a plurality of second stages connected to the second scan lines; and
a data driver connected to the data lines,
wherein each of the first scan lines is connected to pixels arranged in a corresponding row among the rows,
wherein each of the second scan lines is commonly connected to pixels arranged in corresponding 8h rows among the plurality of rows,
wherein h is a natural number,
wherein the first stages sequentially output a plurality of first scan signals in response to a first control signal,
wherein the second stages sequentially output second scan signals in response to a second control signal, which is different from the first control signal, and
wherein a first second scan signal among the second scan signals, which is applied to pixels in a first to an 8h-th rows, is output in synchronization with a falling edge of a first scan signal, which is applied to pixels in the 8h-th row, among the first scan signals.
