Abstract

The present invention relates to a display panel. In an aspect, a source drain electrode layer in a bending region is provided with grooves at positions corresponding to metal traces and the grooves are filled with a conductive material. By using the conductive material to connect to the metal traces, it does not have to consider stress equilibrium for the metal traces in the bending region, thereby reducing a radius of curvature of the bending and a bezel width and increasing a screen-to-body ratio. In another aspect, a pad plate is provided and the pad plate is provided with conductive bridges arranged at intervals at positions corresponding to the grooves. It can be better connected to the metal traces by the conductive bridges, preventing the conductive material from unable to connect to the metal traces.
