Abstract
A display panel driving circuit, an array substrate, and a method of fabricating the array substrate are provided. The display panel driving circuit includes a plurality of transistors. The transistors include a low leakage current thin-film transistor including a semiconductor layer. The semiconductor layer includes a first semiconductor layer and a second semiconductor layer disposed on the first semiconductor layer. A material of the first semiconductor layer or the second semiconductor is low-temperature polysilicon, and a material of the other has a carrier mobility less than a carrier mobility of the low-temperature polysilicon.
