Abstract
An array substrate and an OLED display device are provided. A trace system of the array substrate is designed in a structure with three layers of metal. By providing one layer of inorganic insulation film and one layer of organic insulation film between two layers of metal, a coupling effect between two layers of trace can be reduced. By exposing all or part of an organic insulation film in a region, which will form a second electrode plate of a storage capacitor, a storage capacitor with larger capacitance can be formed. By forming a third metal layer as a mesh structure, it is possible to reduce IR drop without increasing mask and improve display uniformity of the display device.
