Flexible display substrate with wire in curved bending area

A flexible display device comprising:

• a flexible substrate bent in a bending direction across which strain of the flexible substrate is greatest;
• and
• a wire on the flexible substrate including at least one first portion extending in a first direction forming a first angle relative to the bending direction and at least one second portion extending in a second direction forming a second angle relative to the bending direction, wherein the first and second portions being configured to reduce the strain of the wire from being bent in the bending direction,
• wherein the wire includes a plurality of the first portions and second portions forming a network that provides multiple routes for an electrical signal via the wire,
• wherein the first portions of the wire are provided in an inner layer and the second portions of the wire are provided in an outer layer having a greater radius of curvature than the inner layer, wherein a collective total length of the first portions is longer than a collective total length of the second portions.
