摘要： An array substrate includes a first base, and gate lines, data lines and common electrode lines disposed above the first base. The gate lines and the data lines extend in a first direction, and the common electrode lines extend in a direction intersected with the first direction. The gate lines, the data lines and the common electrode lines are insulated from one another. Orthographic projections of the gate lines and the data lines on the first base are not overlapped. The gate lines and/or the data lines define a plurality of sub-pixel regions together with the plurality of common electrode lines.
