Abstract

A display device includes a display panel including unit areas. Each of the unit areas includes pixels arranged in a matrix formation; and data lines (DLs) connected to the pixels. The display device is configured to: apply data voltages of a same polarity to first DLs positioned between adjacent pixel columns; and apply DVs of different polarities to second DLs positioned at respective sides of each pixel column. Each of the pixels is connected to one of the second DLs. A connection direction between the pixels and the DLs in each of a plurality of pixel rows is changed in a determined pixel column interval. Connection directions between the pixels and the DLs are opposite each other in odd-numbered pixel rows adjacent in a column direction. Connection directions between the pixels and the DLs are opposite each other in even-numbered pixel rows adjacent in the column direction.
