Abstract: There is provided a flexible display having a new wire structure and a new insulating layer structure. A flexible display includes a flexible substrate having a first area and a second area. The second area is curved in a non-zero angle relative to the plane of the first area. The flexible display further includes a plurality of wires that extend over from the first area to the second area of the flexible substrate. Each of the wires is covered by an upper insulating pattern, which is separated from other upper insulating pattern. Each upper insulating pattern covering the wire has substantially the same trace pattern shape of the corresponding wire thereunder. Accordingly, by adopting the above-described wire structure and upper insulating layer structure, crack generation and propagation in the wires and the insulating layers from bending of the flexible display can be minimized.
