Problems solved by technology

[0004] Existing ADS array substrates generally use the gate metal layer to make the common electrode lines, use the transparent conductive layer to make the common electrodes, and connect the common electrode lines and the common electrodes through the vias set in the pixel area, due to the number of vias More, so it will affect the aperture ratio of the display device; and because the common electrode line and the common electrode are overlapped together through the via hole, there is also a risk of poor bonding at the via hole, resulting in an increase in the probability of poor display
