More Information
Summary:The array substrate comprises a substrate body, an active layer, a first metal layer and a second passivation layer, the active layer, the first metal layer and the second passivation layer are sequentially arranged on the substrate body, the first metal layer comprises a source electrode and a drain electrode, the active layer comprises doped regions making contact with the source electrode and the drain electrode and channel regions located between the adjacent doped regions, and the second passivation layer is located between the channel regions. The array substrate further comprises at least one hydrogen barrier layer, the hydrogen barrier layer is arranged between the active layer and the second passivation layer, the hydrogen barrier layer at least covers the channel region, and the array substrate is further provided with a drainage hole at least penetrating through the flat layer; according to the array substrate, the hydrogen barrier layer is used for preventing hydrogen ions of the second passivatio
