The invention discloses an array substrate and a making method thereof, a display panel and a display device. The array substrate comprises a substrate body, light shielding layers, a plurality of thin film transistors located on the substrate body in a matrix mode, a plurality of data lines and a plurality of scanning lines, wherein the data lines and the scanning lines are intersected in an insulation mode. The light shielding layers are located on the substrate body and located between the multiple thin film transistors, and comprise a plurality of light shielding pads and a plurality of scanning signal lines; the light shielding pads are located active layers of the thin film transistors and the substrate body; insulation layers are located between the active layers, the scanning lines and the data lines at intervals respectively, gating via holes are formed in the insulation layers between the scanning signal lines and the scanning lines, and the scanning signal lines are electrically connected with the
