Array substrate for display device and manufacturing method thereof

A display device comprising:

• a substrate including an active area and non-active area, the non-active area including a pad area with one or more pads and a dummy area;
• a plurality of gate lines to supply gate signals to a plurality of pixels and a plurality of data lines to supply data signals to the plurality of pixels on the active area;
• a plurality of pixels to display an image in the active area, each of the plurality of pixels including a thin film transistor connected to at least one of the plurality of the date lines and gate lines, and configured to supply a signal to a corresponding pixel;
• a gate pad and data pad connected to at least one of the plurality of the date lines and gate lines on the substrate, the gate pad and data pad being disposed in the pad area;
• a semiconductive layer in the dummy area;
• a conductive layer on the semiconductive layer in the dummy area;
• a passivation layer on the conductive layer in the dummy area;
• an organic layer on the passivation layer in the dummy area;
• and
• a transparent conductive layer on the organic layer, the transparent conductive layer connected to the conductive layer in the dummy area,
• wherein in the dummy area, the transparent conductive layer is provided as a cover layer of the conductive layer.
