Abstract: A method for manufacturing an array substrate includes: providing a base substrate; forming gate lines and data lines intercrossing each other, the gate lines and the data lines define multiple pixel units. Multiple pixel regions are formed in each pixel unit, a display electrode having a slit is formed in each pixel region. Each data line includes multiple data line segments. In each pixel unit, each of a part of the pixel regions has a display electrode whose slit is parallel to a data line segment adjacent to this pixel region; each of another part of the pixel regions has a display electrode whose slit is non-parallel to a data line segment adjacent to this pixel region. The display electrodes in each of the pixel units are located at a same side of the gate line to which the pixel unit where the display electrodes are located is coupled.
