Abstract: The present disclosure provides a display panel and a method for manufacturing the same. The method includes providing a substrate including a display area and a non-display area. A chip on film (COF) and a testing structure are disposed in the non-display area. A testing circuit includes a signal trace including a non-metal trace and a metal trace connecting to each other. A cutting line is disposed on the signal trace. The method further includes testing the display area of the substrate by the testing structure, and removing a test pad.

Abstract: The present application provides a display panel and a display device. The display panel includes a cathode layer formed by a low-temperature process, and a first gap is disposed on the cathode layer. In the present application, generated lines of force are not shielded by the cathode layer because the first gap is disposed on the cathode layer. After a finger touches screen, the generated lines of force can penetrate a structure under the cathode layer. The cathode layer is formed by the low-temperature process, thereby avoiding damage to luminescent material.
