An organic light emitting diode display includes a substrate including a display region displaying an image and a peripheral region surrounding the display region, a plurality of pad wires formed in the peripheral region of the substrate, and a plurality of bumps formed between the plurality of pad wires. The organic light emitting diode display blocks or relieves impact which is generated when a temporary upper protective film is half-cut and applied to a plurality of pad wires or an insulating layer by forming a plurality of bumps between the plurality of pad wires, thus preventing a damage to the pad wires or the insulating layer.
