Abstract

The invention discloses an array substrate and a manufacturing method thereof, and a display device. Therefore, the process steps are reduced, so that the production cost is lowered and the production efficiency is improved. The array substrate includes a substrate base plate, thin-film transistors arranged on the substrate base plate, data lines connected with source electrodes / drain electrodes of all thin-film transistors, and a light shield layer arranged on the substrate base plate. The data lines and the light shield layer are arranged at the same layer. First via holes are formed above the data lines to expose parts of data lines. The thin-film transistors include semiconductor active layers and first transparent electrodes; second via holes are formed above the semiconductor active layers to expose parts of the semiconductor active layers; and the data lines and the semiconductor active layers are electrically connected by the first transparent electrodes through the first via holes and the second via holes.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] At present, thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) has the advantages of small size, low power consumption, no radiation, etc., and occupies a dominant position in the current flat panel display market. Thin Film Transistor (TFT) can be divided into top gate TFT and bottom gate TFT according to its structure. Compared with the bottom-gate TFT, the top-gate TFT structure can greatly reduce the parasitic capacitance between the source-drain electrode and the gate, thereby reducing loading, reducing the size of the gate driving circuit, and further reducing the frame of the display panel. [0003] Such as figure 1 As shown, the top-gate TFT array substrate in the prior art includes: a base substrate 10, a light...
