Abstract: Display panels and array substrates are provided. The array substrate includes a first base, a first metal layer disposed on the first base and including scanning lines, a second metal layer disposed on the first metal layer and including data lines, a third metal layer disposed on the second metal layer and including pixel electrodes, and a fourth metal layer disposed between the third metal layer and the second metal layer. The fourth metal layer includes a transparent shielding electrode in which at least one repair hole is formed. An orthographic projection of the repair hole on the first base overlaps a part of an orthographic projection of at least one of the data lines and the scanning lines on the first base.
