Display device and method for manufacturing the same

A method for manufacturing a display device, the method comprising:

• forming transistors and connection electrodes in a display area on a substrate and forming an auxiliary electrode in a non-display area on the substrate, wherein the display area and the non-display area positioned around the display area are defined on the substrate, and the connection electrodes are connected to the transistors;
• forming a lower insulating layer by applying an organic insulating material onto the substrate on which the connection electrodes and the auxiliary electrode are formed, and etching the lower insulating layer in a way such that a portion of the auxiliary electrode is exposed;
• forming an upper insulating layer by applying an inorganic insulating material onto the substrate on which the lower insulating layer is formed, and etching the upper insulating layer in a way such that a portion of the auxiliary electrode in the non-display area is exposed and portions of the lower insulating layer respectively in emission areas positioned in the display area are exposed;
• etching the lower insulating layer using the upper insulating layer as a mask to pattern the lower insulating layer to be provided with openings corresponding to the portion of the auxiliary electrode and the emission areas;
• forming pixel electrodes respectively in the emission areas and forming a conductive pattern, which is separated from the pixel electrodes, on the exposed portion of the auxiliary electrode and the upper insulating layer, by applying a conductive material onto the substrate on which the patterned lower insulating layer and the upper insulating layer are formed;
• forming a light emitting layer on the substrate on which the pixel electrodes and the conductive pattern are formed;
• and
• forming a common electrode on the substrate on which the light emitting layer is formed.
