Abstract
An array substrate includes a plurality of pixel driving circuits. A respective pixel driving circuit includes a driving transistor, a data write transistor, a first capacitor including a first capacitor electrode and a second capacitor electrode, and a second capacitor including a third capacitor electrode and a fourth capacitor electrode. The second capacitor electrode and the third capacitor electrode are coupled to a second electrode of the data write transistor. The array substrate includes a stacked structure of capacitor electrodes. The stacked structure includes the first capacitor electrode; an insulating layer on the first capacitor electrode; an electrode block including the second capacitor electrode and the third capacitor electrode on a side of the insulating layer away from the first capacitor electrode; an inter-layer dielectric layer on a side of the electrode block away from the insulating layer; and the fourth capacitor electrode on the inter-layer dielectric layer.
