Abstract
A display device can include a display panel having a plurality of sub-pixels configured to display an image, a gate driving circuit configured to drive a plurality of gate lines, and a data driving circuit configured to supply a data voltage to a plurality of data lines. At least one of the plurality of sub-pixels is electrically connected to at least one sub-pixel connected to the same data line among adjacent sub-pixels through a second emission control transistor, thereby allowing data to be shared between the sub-pixels.
