Abstract: A display panel, an array substrate, and a manufacturing method thereof, wherein the array substrate includes a thin film transistor device, and an interface layer, a first transparent conductive layer, a passivation layer, and a second transparent conductive layer which are formed on the thin film transistor device in sequence. By replacing a planarization layer in the prior art with the interface layer, performing a gate re-etching process, and perforating the interface layer and the passivation layer to simultaneously form a deep via and a shallow via, a number of photomasks required to form the array substrate is reduced to 8. It effectively reduces costs of production materials and costs of photomasks.
