A mother substrate for a display panel and a display panel using the same are disclosed. A mother substrate for a display panel includes a conductive ring disposed in a non-display area outside the display area and surrounding each of the display areas, and one or more dummy pixel driving circuits disposed in a non-display area outside the display area. An electrostatic discharge (ESD) prevention structure inside the dummy pixel driving circuit can prevent defects of display panels due to ESD occurring in the manufacturing process of the display panel.

Mother substrate and display panel using the same

A mother substrate for a display panel and a display panel using the same are disclosed. The mother substrate comprises a plurality of display area including a plurality of light-emitting areas configured to receive light-emitting elements, a plurality of wirings, and a plurality of pads connected to the plurality of wirings; a conductive ring in a non-display area that surrounds the display area such that each of the display areas is surrounded by the conductive ring and electrically connected to the pads; a photoresist pattern covering the plurality of display areas and the non-display area; and a first metal layer covering the photoresist pattern. The conductive ring includes an electrostatic blocking area.
