Abstract: A method for manufacturing a display panel, a display panel, and a display device are provided. The method includes: forming a plurality of gate lines and a common electrode line pattern on a base substrate; forming an insulating layer on the base substrate on which the plurality of gate lines and the common electrode line pattern are formed; forming a via hole on the insulating layer; and forming a metal conductive pattern on the base substrate on which the insulating layer is formed. The common electrode line and the common electrode connection block located on two sides of a gate line are electrically connected through a bridging structure in a conductive layer made of metal, which reduces the resistance of the bridging structure, so that the voltage uniformity throughout the common electrode line pattern which is bridged through the bridging pattern is high.

Abstract: The disclosure provides a shift register, a driving method for the shift register, a gate driving circuit and a display device. The shift register comprises an input component, a reset component, a node control module, a chamfering control component and an output component. By setting the chamfering control component and cooperation among the above five components, an amplitude of a scanning signal output by a driving signal output terminal is changed so as to generate a scanning signal with a chamfered waveform. When the scanning signal with the chamfered waveform is sequentially input to each pixel unit in a corresponding row by a corresponding gate line, a jump voltage ΔVp on a pixel electrode of the pixel unit can be reduced, thereby mitigating phenomena such as flashing and image sticking of the display panel and improving the display quality of the display panel.
