Dual-gate array substrate and display device

A dual-gate array substrate, comprising:

• a plurality of gate lines arranged in a first direction, each of the gate lines being extended in a second direction that is perpendicular to the first direction;
• a plurality of primary signal lines and secondary signal lines arranged alternately in the second direction and extended in the first direction;
• and
• a plurality of pixel units each enclosed and defined by jointing adjacent two of the gate lines insulative with corresponding ones of the primary signal lines or the secondary signal lines, the pixel units each including pixel electrodes, the primary signal lines being connected to a drive unit and being connected respectively to ones of the pixel units that are adjacent thereto;
• wherein the dual-gate array substrate further comprises common electrodes located in a different layer from the pixel units and comprising a plurality of main electrodes and a plurality of branching electrodes;
• and
• wherein an orthographic projection of one of the main electrodes on the dual-gate array substrate at least covers a corresponding one of the primary signal lines and does not overlap orthographic projections of two ones, adjacent to the corresponding one of the primary signal lines, of the pixel electrodes on the dual-gate array substrate.
