Abstract: A conductive trace design is described that minimizes the possibility of crack initiation and propagation in conductive traces during bending. The conductive trace design has a winding trace pattern that is more resistant to the formation of cracks at high stress points in the conductive traces. The conductive trace design includes a cap that helps ensure electrical connection of the conductive trace even though one or more cracks may begin to form in the conductive portion of the conductive trace.

Abstract: The organic light emitting display device includes a flexible substrate, a thin-film transistor on the flexible substrate, a first anode on the thin-film transistor, a second anode on the same plane with the first anode and spaced apart from the first anode so as to surround the first anode, an organic light emitting layer on the first anode and the second anode, and a cathode on the organic light emitting layer. The second anode includes an opening where the first anode is encompassed therein. The shape of the first anode and the second anode and arrangement thereof reduces a segment length of an anode in a bending direction of the organic light emitting display device, and, thus, occurrence of cracks in the anode can be minimized.
