Abstract
A display device includes (i) a substrate having a first area, a second area, and a bending area located between the first area and the second area, where the substrate is bent along a bending axis in the bending area, the substrate includes a thin portion at an edge portion of the bending area, and the thin portion extends from the second area to the first area and has a thickness less than a thickness of the substrate at a center of the bending area; and (ii) an inorganic insulating layer over the substrate, where the inorganic insulating layer exposes the thin portion in the bending area.
Claims52
A display device comprising:
- a substrate having a first area, a second area, and a bending area disposed between the first area and the second area, wherein the substrate is bent along a bending axis in the bending area, the substrate comprises a thin portion at an edge portion of the substrate in the bending area, the thin portion extends from the second area to the first area along the edge portion of the substrate, and a thickness of the substrate at the thin portion in the bending area is less than a thickness of the substrate at a center of the first area;
- and an inorganic insulating layer over the substrate, wherein the inorganic insulating layer exposes the thin portion in the bending area;
- wherein the thin portion defines a first groove extending from the second area to the first area, and the inorganic insulating layer has a first opening corresponding to the first groove;
- further comprising a metal layer which covers an inner side surface of the first opening and a bottom surface of the first groove.
A display device comprising:
- a substrate having a first area, a second area, and a bending area disposed between the first area and the second area, wherein the substrate is bent along a bending axis in the bending area, the substrate has a first groove at an edge portion of the substrate in the bending area, the first groove is a recessed part of the substrate at the edge portion of the substrate, a thickness of the substrate at the first groove is less than a thickness of the substrate at a center of the first area, and the first groove extends from the second area to the first area along the edge portion of the substrate;
- and an inorganic insulating layer over the substrate, wherein part of the inorganic insulating layer on the bending area exposes the first groove in the bending area;
- wherein the inorganic insulating layer has a first opening corresponding to the first groove;
- further comprising a metal layer which covers an inner side surface of the first opening and a bottom surface of the first groove.
