Provided are an array substrate, a display panel, and a display apparatus. The array substrate includes a display region, a substrate, pixel driving circuits, and scanning signal lines. The display region includes a plurality of pixel regions. At least part of a pixel driving circuit and at least part of a scanning signal line are located in the display region and on the same side of the substrate. The scanning signal line extends in a first direction. At least part of the pixel driving circuit is located in a pixel region and includes thin-film transistors. A thin-film transistor includes a gate and a channel layer. The gate is a portion where the scanning signal line overlaps the channel layer. The array substrate further includes auxiliary signal lines. An auxiliary signal line is located in the display region and extends in the first direction.
