Claim of US Patent No. 10,716,205

1. A display comprising:a flexible substrate including a plurality of unit wiring structures and an insulation sheet on which the plurality of unit wiring structures are disposed, wherein
each of the plurality of unit wiring structures comprises a central section and a plurality of strips disposed at an outer side of the central section,
each of the plurality of strips has a first end and a second end, and is curved along an outer periphery of at least part of the central section, the first end connected to the central section,
the plurality of strips in each of the plurality of unit wiring structures curve in a clockwise or a counterclockwise manner with the central section as a center of rotation,
the plurality of unit wiring structures include at least four unit wiring structures arranged in a two-dimensional manner,
between adjacent unit wiring structures from among the at least four unit wiring structures, the second end of at least one of the plurality of strips of one unit wiring structure and the second end of at least one of the plurality of strips of the other unit wiring structure are mutually connected,
the plurality of unit wiring structures, in a plan view, include a gap between the mutually connected strips and the central section, and/or between the mutually connected strips and another strip, and is configured to extend and contract in a planar direction and a perpendicular direction of the flexible substrate due to curvatures of curves of the mutually connected strips changing, and
the insulation sheet, in a plan view, includes a gap between the mutually connected strips and the central section, and/or between the mutually connected strips and another strip,
light emitting elements each disposed on the central section of a corresponding one of the plurality of unit wiring structures, and
a controller configured to drive the light emitting elements for display.
