Array substrates and display panels

A display panel, comprising:

• an array substrate, comprising:
• a first base;
• a first metal layer, disposed on the first base and comprising scanning lines;
• a second metal layer, disposed on a side of the first metal layer and comprising data lines;
• a third metal layer, disposed on a side of the second metal layer away from the first metal layer and comprising pixel electrodes;
• and
• a fourth metal layer, disposed between the third metal layer and the second metal layer and comprising a transparent shielding electrode;
• a color filter substrate;
• and
• a liquid crystal, sandwiched between the array substrate and the color filter substrate,
• wherein one or more repair holes are formed in the transparent shielding electrode, a first orthographic projection of each of the one or more repair holes on the first base overlaps a part of a second orthographic projection of at least one line of the data lines and the scanning lines on the first base, and a third orthographic projection of the transparent shielding electrode on the first base overlaps the second orthographic projection.
