Abstract

Embodiments of the invention provide a manufacturing method of an array substrate, the array substrate and a display device. The manufacturing method is characterized by firstly opening a hole on a first thin film transistor, then simultaneously performing hydrogen supplement processing for the first thin film transistor and a second thin film transistor, and opening a hole on the second thin filmtransistor, so that the first thin film transistor and the second thin film transistor can be repaired and compensated to different degrees through the hydrogen supplement processing respectively, wherein, because the hole is opened on the first thin film transistor firstly, the hydrogen supplementing effect of the first thin film transistor is weakened, in this way, the gradient of a current-voltage curve of the first thin film transistor can be properly reduced, a current difference caused by a threshold voltage difference is reduced, and electron mobility of the second thin film transistoris increased as much as possible, the charging electric quantity of a capacitor within the rated time is increased, the current difference between circuits is reduced, therefore, the display device can emit light uniformly, the occurrence probability of Mura is reduced, and the Mura effect is reduced.
