Abstract
A display panel and a method of manufacturing the same are provided. The display panel includes a shielding layer, a thin film transistor device layer, and a first via hole and a second via hole disposed correspondingly, and a third via hole disposed in a bonding area. Specifically, each of the first via hole and the third via hole is a stair-step shaped hole. The first via hole, the second via hole, and the third via hole are etched through a same etching process. Only one-time mask process is required, which saves number of masks and lowers the production cost.
