An array substrate, a method of producing the array substrate, and a display panel incorporating the array substrate are disclosed. The array substrate includes a substrate, a gate line, a data line, and a spacer. The gate line and the data line are arranged over the substrate. The spacer is arranged over the gate line and the data line. The gate line and/or the data line is provided with a via hole at a position corresponding to a spacer. In this manner, a problem of a display panel having gaps of different sizes after assembly because of non-uniform thicknesses of the gate line and/or the data line can be avoided, which, in turn, prevents inhomogeneous color in the display.
