Abstract

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

Description

technical field [0001] Exemplary embodiments relate to a display device. More particularly, exemplary embodiments relate to a display device capable of improving crosstalk and flicker. Background technique [0002] Liquid crystal displays (LCDs) are among the most widely used flat panel displays. A liquid crystal display generally includes display panels in which electrodes are formed and a liquid crystal layer interposed between the display panels. The voltage applied to the electrodes forms an electric field to align the liquid crystal molecules of the liquid crystal layer to control the transmittance of light according to the orientation of the liquid crystal molecules, and in this way to display images. Liquid crystal displays are generally lightweight and have a thin shape. However, it should be noted that liquid crystal displays may have lower side visibility than front visibility. Various types of liquid crystal arrangements and driving methods have been developed...
