1. An electronic device comprising:
a display panel comprising a plurality of data lines, a plurality of scan lines, and a plurality of pixels connected to the data lines and the scan lines;
a plurality of scan stages corresponding to the scan lines, wherein each of the scan stages receives clock signals and a carry signal, and outputs a scan signal;
a plurality of masking circuits electrically connected to at least two scan stages among the scan stages, respectively, wherein each of the masking circuits receives a masking signal and outputs a masking carry signal in response to the masking signal and the scan signal of a corresponding stage connected thereto as the carry signal of a next stage of the corresponding stage connected thereto; and
a plurality of transmission circuits electrically connected to remaining scan stages among the scan stages other than the at least two stages, respectively, wherein each of the transmission circuits does not receive the masking signal and outputs the scan signal output from a corresponding scan stage connected thereto as the carry signal of a next stage of the corresponding stage connected thereto.
