Abstract: The present disclosure provides an array substrate and a method for manufacturing the same, and a display apparatus. The array substrate comprises a shielding electrode driven independently, and the shielding electrode covers at least one gate line and/or at least one data line. The shielding electrode can isolate a signal of the at least one gate line and/or the at least one data line, so that the signal of the at least one gate line and/or the at least one data line is prevented from interfering with normal deflections of liquid crystal molecules of a liquid crystal display. Moreover, since the shielding electrode is driven independently, the shielding electrode will not affect a voltage of a common electrode of the liquid crystal display.
