Array substrate, display panel and display device

The utility model provides an array substrate, a display panel and a display device so as to reduce generation of poor short circuit between a grid electrode and a source electrode and poor short circuit between the source electrode and a common electrode wire, thereby improving the product yield. The array substrate comprises, along a thickness direction, a substrate; the gate line fixing part and the common electrode are made of the same conductive material and are located in the same structural layer; the gate line is arranged on a gate line fixing part, the common electrode routing line is arranged on a common electrode, and the gate line fixing part is used for fixing the gate line on the substrate. The display panel comprises the array substrate. The display device comprises the display panel. 本申请提供一种阵列基板、显示面板和显示装置，以降低栅极与源极短路不良以及源极与公共电极走线短路不良的产生，从而提高了产品良率。该阵列基板沿厚度方向包括：衬底基板；栅极线固定部和公共电极，栅极线固定部和公共电极的材料为相同的导电材料且位于同一结构层中；设置在栅极线固定部上的栅极线、以及设置在公共电极上的公共电极走线，所述栅极线固定部用于将所述栅极线固定于所述衬底基板上。该显示面板包括该阵列基板。该显示装置包括该显示面板。
