Abstract: A driver includes first to Mth stages, where a first input signal and a second input signal are input to each of the first to Mth stages, and each of the first to Mth stages outputs a stage output signal, a first carry signal, and a second carry signal, where M is a natural number greater than or equal to 2. The first carry signal and the second carry signal output from a kth stage are the first input signal and the second input signal, which are input to a (k+1)th stage, respectively, where k is a natural number greater than or equal to 1 and less than M, and the first input signal and the second input signal, which are input to a first stage, are a first start signal and a second start signal which are alternately changed for predetermined frame times, respectively.
