Abstract: A driving circuit includes: a plurality of scan stages each corresponds to a plurality of scan lines, receives clock signals and a carry signal, and outputs a scan signal; and a plurality of masking circuits corresponding to some scan stages, respectively, among the scan stages. each masking circuit outputs one of the scan signal output from a corresponding scan stage and a first voltage as a masking carry signal in response to a masking signal. A j-th scan stage receives a scan signal output from a (j−a)th scan stage as the carry signal when the (j−a)th scan stage is not one of the some first scan stages, and the masking carry signal output from a masking circuit corresponding to the (j−a)th scan stage as the carry signal when the (j−a)th scan stage is one of the some first scan stages.

Abstract: A display panel of a display device is divided into a first display region and a second display region. The second display region includes a boundary region adjacent to the first display region and a non-boundary region opposite to the first display region with respect to the boundary region. The driving controller outputs the voltage control signal, such that the first voltage in a first high voltage level and the second voltage in a first low voltage level are generated when the first display region is driven. The driving controller outputs the voltage control signal, such that the first voltage in a second high voltage level lower than the first high voltage level and the second voltage in a second low voltage level higher than the first low voltage level are generated, when the non-boundary region of the second display region is driven.
