Abstract: An array substrate and a display panel including the array substrate are provided. The array substrate has a display area and a fan-shaped wiring area. A first metal layer, a second metal layer, and a third metal layer are arranged in both the display area and the fan-shaped wiring area, and a fourth metal layer is arranged in the fan-shaped wiring area. In the display area, the first metal layer includes gate lines, the second metal layer includes data lines, and the third metal layer includes touch lines. Fingerprint identification signal lines are arranged in the fan-shaped wiring area and are electrically connected to fingerprint identification units arranged in the display area. The fourth metal layer arranged in the fan-shaped wiring area includes at least one of the fingerprint identification signal lines, which avoids too many fingerprint identification signal lines being arranged in the same layer with other signal lines.
