Abstract
An array substrate, a manufacturing method and a maintenance method thereof, and a display device. The array substrate includes a base substrate, a signal line layer, a color filter layer, and a common line layer. The signal line layer includes multiple signal lines. The common line layer includes a plurality of first common lines and second common lines. An orthographic projection of each signal line on the base substrate is substantially parallel to an orthographic projection of each second common line on the base substrate. An orthographic projection of each signal line on the base substrate and orthographic projections of the plurality of first common lines on the base substrate have overlapping areas. A via hole penetrates the color filter layer, and an orthographic projection of the via hole on the base substrate at least partially overlaps the overlapping area.
