Abstract: An electronic device includes a display panel including pixels respectively connected to scan lines, scan stages corresponding to the scan lines, where each of the scan stages receives a carry signal, and outputs a scan signal, masking circuits electrically connected to some of the scan stages, respectively, where each of the masking circuits outputs a masking carry signal in response to a masking signal and the scan signal, and transmission circuits electrically connected to others of the scan stages, respectively, where each of the transmission circuits outputs the scan signal output from a corresponding scan stage among the scan stages. A j-th (j is an integer greater than 1) scan stage among the scan stages receives one of the scan signal output from a (j−1)-th scan stage and the masking carry signal as the carry signal.
