Abstract
In a lower substrate, a display apparatus having the lower substrate and a method of manufacturing the lower substrate, the lower substrate includes a pixel area and a circuit area. An image is displayed in the pixel area. A first signal electrode is disposed in a circuit area. A first insulating layer includes an opening, through which the first signal electrode is exposed. A second signal electrode is disposed on the first insulating layer in the circuit area, and spaced apart from the first signal electrode. A second insulating layer is disposed on the first insulating layer, and includes a contact hole, through which the first and second signal electrodes are exposed. A conductive layer electrically connects the first signal electrode to the second signal electrode. Therefore, a manufacturing process is simplified so that a yield of the lower substrate is increased.
