A display device includes a first display panel, a first gate driver, a second display panel and a second gate driver. The first display panel includes a first display region, in which first gate lines are formed, and a first peripheral region surrounding the first display region. The first gate driver is formed at the first peripheral region and outputs a first gate signal to the first gate lines in response to a first clock signal and a second clock signal. The second display panel is electrically connected with the first display panel. The second display panel includes a second display region, in which second gate lines are formed, and a second peripheral region surrounding the second display region. The second gate driver is formed at the second peripheral region and outputs a second gate signal to the second gate lines in response to the first clock signal and second clock signal.
