An organic light-emitting diode display is disclosed. In one aspect, the display includes a substrate including a display area configured to display an image and a peripheral area surrounding the display area, a plurality of scan lines formed over the substrate and a plurality of data lines crossing the scan lines. A plurality of pixels is formed in the display area and electrically connected to the scan lines and the data lines, a repair ring is formed in the peripheral area and surrounding the display area, and the repair ring includes a first portion and a connecting portion different from the first portion. The first portion has a width less than that of the connecting portion different from the first portion. A driving circuit is configured to generate a data signal that is output to the data lines and the repair ring.
