Abstract: A display device includes a display panel including pixels in one pixel column and a gate driver for sequentially providing scan signals to the pixels. Each of the pixels includes a light emitting element, a first transistor for controlling a current amount of driving current flowing through the light emitting element and a second transistor for transferring a data signal to a gate electrode of the first transistor in response to a corresponding scan signal among the scan signals. A first pixel among the pixels is electrically connected to a first data line, and a second pixel adjacent to the first pixel among the pixels is electrically connected to a second data line different from the first data line. A second scan signal provided to the second pixel partially overlaps with a first scan signal provided to the first pixel.
