Abstract
An array substrate is provided. The array substrate includes a base substrate, and a plurality of pixel driving circuits configured to drive light emission in a plurality of subpixels. A respective pixel driving circuit includes a driving transistor; a compensation transistor configured to provide a compensation voltage signal to a gate electrode of the driving transistor; the compensation transistor including a source electrode, a drain electrode and a gate electrode; a node connecting line in a first signal line layer; a first pad in a second signal line layer on a side of the first signal line layer away from the base substrate; a voltage line configured to output a constant voltage signal; and a voltage connecting line electrically connecting the first pad with the voltage line. The node connecting line connects the gate electrode of the driving transistor and a drain electrode of the compensation transistor.
