Abstract: A display device includes first pixels in a first pixel region and connected to first scan lines and second pixels in a second pixel region connected to second scan lines. The second pixel has a width less than the first pixel region. The display device also includes a first scan driver to supply first scan signals to the first scan lines, a second scan driver to supply second scan signals to the second scan lines, a first signal line to supply a first driving signal to the first scan driver and the second scan driver, and a signal delay circuit connected to the first signal line to delay the first driving signal.
