An array substrate is disclosed. The array substrate comprises a substrate, a plurality of common electrodes formed on the substrate, a plurality of gate signal lines formed above the common electrodes, and a plurality of common electrode signal line units corresponding to the plurality of common electrodes, respectively. The plurality of common electrode signal line units are formed on the corresponding common electrodes, respectively. Each of the common electrode signal line units comprises a first common electrode signal line perpendicular to the gate signal line and a second common electrode signal line parallel to the gate signal line. The first and second common electrode signal lines are made of metal and cross with each other and are electrically connected to each other. Two adjacent common electrode signal line units are electrically connected by a bridge line. The present disclosure also relates to a method for manufacturing the array substrate and a display apparatus.
