Abstract
There is provided a flexible display having a plurality of innovations configured to allow bending of a portion or portions to reduce apparent border size and/or utilize the side surface of an assembled flexible display.
Claims10
A display apparatus comprising:
- a base layer having a first portion with a display area thereon and having a second portion with a non-display area that is bent towards an underside of the first portion along a bend line that is parallel to a short side of the base layer, the second portion having smaller width than the first portion;
- a plurality of conductive lines extending parallel to a bending direction on the second portion of the base layer;
- a cut edge at two corners of the first portion adjacent to the bend line and at four corners of the second portion, the cut edge has curved shape on the corner where the second portion meets the first portion;
- and
- a crack stop pattern extending from a scribed edge of the second portion to the first portion along the corner where the second portion meets the first portion, and disposed between the plurality of conductive lines and the cut edge having the curved shape, and
- wherein the crack stop pattern has a stacked structure of a plurality of insulating layers on the base layer, at least one of the insulating layers at sides of the crack stop pattern removed along the cut edge having the curved shape of the base layer.
