Abstract
In an array substrate of the present invention, only two insulating layers are arranged on a planarization layer. Compared with conventional techniques that require at least four insulating layers arranged on the planarization layer, a number of the insulating layers arranged on the planarization layer is reduced. Therefore, a number of photomasks is reduced in a manufacturing process of the array substrate, and the manufacturing process is simplified. The present invention also provides a manufacturing method of the array substrate, and a display panel.
