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.

Abstract: A display panel, a pixel driving circuit, and a display device are provided. Driving transistors include a first transistor and a second transistor connected in parallel. An absolute value of a threshold voltage of the first transistor is greater than an absolute value of a threshold voltage of the second transistor. A carrier mobility of the first transistor is greater than a carrier mobility of the second transistor. A driving current is affected by characteristics of the second transistor and an increase speed is slowed down, which improves a problem of color unevenness of the display panel at low brightness.
