Abstract
An array substrate includes a plurality of pixel driving circuits, and each pixel driving circuit at least includes a compensation transistor. The array substrate includes a substrate, an active layer, a first gate layer and a second gate layer. The active layer includes an active layer pattern of the compensation transistor, which includes two channel areas and a conductive area therebetween. The first gate layer includes a first gate signal line, and an orthographic projection of the first gate signal line on the substrate is overlapped with orthographic projections of the two channel areas on the substrate. The second gate layer includes a voltage stabilization pattern, which is configured to receive a power supply voltage signal, and an orthographic projection of the voltage stabilization pattern on the substrate is overlapped with an orthographic projection of the conductive area on the substrate.
