An array substrate and a preparation method therefor, and a display panel. The array substrate comprises: an underlayment substrate (200), a gate line (202) and a data line (205) on the underlayment substrate (200), and a plurality of pixel units (20). Each of the pixel units (20) comprises a first thin-film transistor, a pixel electrode (208) and at least one second thin-film transistor connected to the first thin-film transistor in series. The pixel electrode (208) is connected to a drain electrode (207') of the second thin-film transistor, a source electrode (206') of the second thin-film transistor is connected to a drain electrode (207) of the first thin-film transistor, and a source electrode (206) of the first thin-film transistor is connected to the data line (205). The array substrate can reduce leakage currents when a thin-film transistor is switched off. |
