1. A display, comprising:

  • a substrate having a peripheral edge;

    thin-film circuitry on the substrate that is configured to form pixels, wherein the thin-film circuitry includes a first inorganic dielectric layer and an organic layer that overlaps the first inorganic dielectric layer;

    thin-film encapsulation that covers the thin-film circuitry, wherein the thin-film encapsulation includes at least a second inorganic dielectric layer; and

    a crack-stopper structure that runs along the peripheral edge and surrounds the pixels, wherein the first and second inorganic dielectric layers overlap the crack-stopper structure, the crack-stopper structure comprising;

    a portion of the organic layer; and

    a polymer line with tapered sidewalls, wherein the tapered sidewalls form an overhang that overlaps the portion of the organic layer.
