Abstract:
A display device includes a plurality of gate lines; a plurality of data lines; a plurality of pixel electrodes electrically connected with the plurality of data lines; a plurality of common electrodes corresponding to two or more pixel electrodes among the plurality of pixel electrodes; a data driving circuit outputting data voltages to the plurality of data lines; and a driving circuit outputting a first driving signal with a first voltage level to at least one common electrode among the plurality of common electrodes during a first driving period and a second driving signal with a second voltage level and a third voltage level to the at least one common electrode during a second driving period, the second driving signal being a pulse signal, wherein the second voltage level and the third voltage level differ from the first voltage level.
