ARRAY SUBSTRATE, DISPLAY PANEL, AND DISPLAY DEVICE

An array substrate, comprising a substrate, a plurality of pixel driving circuits, and a plurality of first scanning signal lines. The plurality of pixel driving circuits are located on one side of the substrate and are arranged in a plurality of rows and a plurality of columns. One pixel driving circuit comprises a compensation transistor, a driving transistor, and a first conductive connecting portion, wherein a control electrode of the driving transistor and a second electrode of the compensation transistor are both electrically connected to the first conductive connecting portion. The plurality of first scanning signal lines are located on one side of the substrate. The plurality of first scanning signal lines all extend in a row direction and are sequentially arranged in a column direction. The row direction and the column direction are both parallel to the substrate and are arranged crosswise. One first scanning signal line is electrically connected to control electrodes of compensation transistors of a
