Abstract
An array substrate, a manufacturing method thereof and a display device are disclosed. The array substrate includes a substrate (10) and first thin-film transistors (TFTs) (21) and first electrodes (40) formed on the substrate (10). The first TFT (21) includes a gate electrode (200), an active layer (202), a source electrode (205) and a drain electrode (204). The first electrode (40) is electrically connected with the drain electrode (204) of the first TFT (21), at least covers an area of the active layer (202) of the first TFT, not overlapped with the source electrode (205) and the drain electrode (204), and can absorb ultraviolet (UV) light. The array substrate can solve the problem of reducing the display performance of the display device as the performances degrade and even fail due to UV irradiation of the TFTs.
