    Abstract: A display device includes a display substrate, a main circuit board, and first and second connection circuit boards. The display substrate includes a base layer, an insulating layer on the base layer, a first signal line on the base layer, a second signal line on the base layer, a first pad exposed from the insulating layer and connected to the first signal line, and a second pad connected to a side surface of the second signal line and disposed on a side surface and a bottom surface of the base layer. The first connection circuit board electrically connects the first pad and the main circuit board, and the second connection circuit board electrically connects the second pad and the main circuit board.

    Abstract: A display apparatus is disclosed. In one aspect, the apparatus includes a display panel including pixels connected to gate lines and data lines, a gate driver driving the gate lines, a data driver driving the data lines, and a control circuit controlling the gate driver and the data driver to display an image on the display panel. The control circuit applies a common voltage to the display panel. The control circuit compares the common voltage applied to the display panel and a feedback common voltage fedback from the display panel and applies a gate-on voltage having a voltage level corresponding to the compared result to the gate driver.

    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.
