1. A flexible display, comprising:
a base layer having a substantially flat portion and a bend portion that is curved away from a plane of the substantially flat portion; a plurality of insulation layers on the base layer, said plurality of insulation layers providing a high leveled surface and a low leveled surface such that a step is created between the high leveled surface and the low leveled surface; a conductive line trace laid over the high leveled surface and the low leveled surface, wherein the conductive line trace has a reinforced portion at the step; and a metal layer that is positioned under a first insulation layer providing the high leveled surface and a second insulation layer providing the low leveled surface, wherein a width of the reinforced portion is greater than a width of a portion of the conductive line trace adjacent to the reinforced portion, wherein at least some portion of the conductive line trace laid in the bend portion of the base layer has a bend stress relief trace design in which the conductive line trace splits and merges back at an interval, wherein the reinforced portion of the conductive line starts on the high leveled surface and ends on the low leveled surface, and wherein the step between the high leveled surface and the low leveled surface is provided within the substantially flat portion within an inactive area of the flexible display. |
