Array substrate and display panel

A display panel, comprising an array substrate, wherein the array substrate comprises:

• a substrate layer;
• a display region;
• a non-display region surrounding the display region;
• at least one notch in the non-display region;
• a plurality of gate lines, a first metal layer;
• and
• a second metal layer;
• wherein the plurality of gate lines comprises regular gate lines and irregular gate lines, wherein each of the regular gate lines is located in the display region and extends in a first direction;
• wherein each of the irregular gate lines comprises a regular section located in the display region and extends in the first direction and an irregular section located in the non-display region around the notch, wherein the regular section and the irregular section of the same irregular gate line are electrically connected to each other;
• wherein the irregular section comprises at least one of a first sub-section and a second sub-section, wherein the first sub-section and the second sub-section of the same irregular section are electrically connected to each other, and a resistivity of the first sub-section is greater than a resistivity of the second sub-section;
• wherein the first metal layer is located at a surface of the substrate layer, the second metal layer is located over a surface of the first metal layer facing away from the substrate layer;
• and
• wherein the regular gate lines, the regular section in each of the irregular gate lines and the first sub-section of each of the irregular sections, are located in the first metal layer, and the second sub-section of each of the irregular sections are located in second metal layer.
