Abstract: A display device includes a display panel including first to fourth panel pads and a connection board including first to fourth connection board pads coupled to the first to fourth pads, respectively. The first and second panel pads are electrically connected to each other, and the third and fourth panel pads are electrically connected to each other. The connection board includes a driving circuit which generates a first test result signal based on a first panel test signal transmitted to the first connection board pad and a first panel feedback signal received from the second connection board pad, generates a second test result signal based on a second panel test signal transmitted to the third connection board pad and a second panel feedback signal received from the fourth connection board pad, and sequentially outputs the first and second test result signals as a test result signal.
