Abstract
A flexible wiring board that includes a flexible substrate; a flexible wiring over the flexible substrate; and a protective layer over the flexible substrate, where the protective layer includes: a first region that overlaps with the flexible wiring and a second region that does not overlap with the flexible wiring as viewed from a thickness direction of the flexible substrate, and a low flexibility part that is higher in flexibility ratio than the first region and is disposed along an extending direction of the flexible wiring in the second region.
Claims18
A flexible wiring board comprising:
- a flexible substrate;
- a flexible wiring over the flexible substrate;
- and
- a protective layer over the flexible substrate, wherein the protective layer includes:
- a first region that overlaps the flexible wiring and a second region that does not overlap with the flexible wiring as viewed from a thickness direction of the flexible substrate, and
- a low flexibility part that is higher in flexibility ratio than the first region and is disposed along an extending direction of the flexible wiring in the second region, wherein
- the second region extends on each of opposed sides of the flexible wiring in a width direction of the flexible wiring transverse to the extending direction of the flexible wiring, and
- the low flexibility part is in each of the second regions.
A flexible wiring board comprising:
- a flexible substrate;
- a flexible wiring over the flexible substrate;
- and
- a protective layer over the flexible substrate, wherein the protective layer includes:
- a first region that overlaps the flexible wiring and a second region that does not overlap with the flexible wiring as viewed from a thickness direction of the flexible substrate, and
- a low flexibility part that is higher in flexibility ratio than the first region and is disposed along an extending direction of the flexible wiring in the second region,
- wherein the protective layer is between the flexible wiring and the flexible substrate in the thickness direction of the flexible substrate, and the protective layer also covers the flexible wiring.
