Abstract: A display device that is capable of being manufactured through a simplified process and at reduced cost is disclosed. The display device is configured such that a plurality of grouped cathode electrodes and a plurality of grouped black matrices intersect each other in the state in which an encapsulation unit is disposed therebetween in order to form a touch sensor, so that a process of forming first and second touch electrodes is omitted and a separate adhesion process becomes unnecessary, whereby structural simplification is achieved while costs are reduced.

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: Provided is a flexible organic light-emitting display device. The flexible display device includes a flexible substrate having a display area, a non-display area, and a bending area. On the flexible substrate, a first insulation layer is formed in a part of the non-display area. The first insulation layer includes a zigzag pattern. A plurality of wirings are electrically connected to the display area and are extended to traverse the non-display area and the bending area and are disposed on the first insulation layer. On the first insulation layer and the plurality of wirings, a passivation layer is formed. By virtue of a zigzag pattern of the first insulation layer, the frequency of occurrence of cracks in the passivation layer is reduced.
