Array substrate and manufacturing method thereof, and display device

An array substrate, comprising a base substrate, a Gate driver On Array (GOA) circuit, a source electrode integrated circuit and Propel Link Gate (PLG) wires, wherein the GOA circuit, the source electrode integrated circuit and the PLG wires are arranged in a peripheral area of the base substrate, and the PLG wires are configured for connecting the GOA circuit with the source electrode integrated circuit;

• the GOA circuit is configured for transmitting a GOA signal, and the GOA signal comprises a cascade signal and a non-cascade signal;
• the PLG wires comprise a first PLG wire group and at least one second PLG wire group, wherein the first PLG wire group is configured for transmitting the cascade signal, the second PLG wire group is configured for transmitting the non-cascade signal, a line width of the first PLG wire group is smaller than a line width of the second PLG wire group, and the first PLG wire group is located at a side of the second PLG wire group that is distal to an active area of the base substrate.
