Abstract: The present invention relates to a thin film transistor, an array substrate and a display panel thereof. The present invention obtains SiNx layers with different densities and hydrogen contents by adjusting a SiNx film forming process of an interlayered insulating layer in a thin film transistor. The second layer having a lower density has a higher hydrogen content, but has a poor hydrogen barrier capability, while the first layer having a higher density has less hydrogen content, but has a better hydrogen barrier capability. Through a combination of SiNx layers having different densities, the hydrogen replenishment capability can be differentiated, thereby achieving different degrees of adjustment of electrical properties of the low-temperature polysilicon thin film transistor, simplifying the channel doping process, thus reducing the production cost.
