Abstract

A display apparatus includes: a first area; a first bent area outside the first area, the first bent area being bent about a first bending axis; and a second bent area outside the first area, the second bent area being adjacent to an edge of the first area extending in a direction crossing the first bending axis, and being bent about a second bending axis that is parallel with an imaginary line extending in a direction crossing the first bending axis. A cut-off portion extends into the first area, the cut-off portion being at a portion where a first line crosses a second line, the first line being parallel with the first bending axis and passing through the first bent area, and the second line being parallel with the second bending axis and passing through the second bent area.

First claim

What is claimed is:

1 . A display apparatus comprising:
a first area; a first bent area outside the first area, the first bent area being bent about a first bending axis; and a second bent area outside the first area, the second bent area being adjacent to an edge of the first area extending in a direction crossing the first bending axis, and being bent about a second bending axis that is parallel with an imaginary line extending in a direction crossing the first bending axis, wherein a cut-off portion is at a portion where a first line crosses a second line, the first line being parallel with the first bending axis and passing through the first bent area, and the second line being parallel with the second bending axis and passing through the second bent area, the cut-off portion extending into the first area.

2 . The display apparatus of claim 1 , further comprising a third area separated from the first area and connected to the first area via the second bent area.

3 . The display apparatus of claim 1 , wherein the first area is flat.

4 . The display apparatus of claim 1 , wherein an extension portion of the cut-off portion within the first area has a shape that is a part of a circle on a plane parallel to the first area and partially overlapping the first area.

5 . The display apparatus of claim 4 , wherein a center of the circle is located outside the first area.

6 . The display apparatus of claim 1 , wherein an extension portion of the cut-off portion within the first area does not have a sharp portion on a plane parallel to the first area.

7 . The display apparatus of claim 1 , further comprising:
a substrate; and an insulating layer over the substrate, wherein a side end surface of the substrate and a side end surface of the insulating layer form a continuous side surface at the cut-off portion.

8 . The display apparatus of claim 1 , further comprising:
a substrate; and an insulating layer over the substrate, wherein a side end surface of the substrate and a side end surface of the insulating layer form a continuous side surface at an extension portion of the cut-off portion within the first area.

9 . The display apparatus of claim 1 , wherein a display area comprises at least a portion of the first area and at least a portion of the second bent area.

10 . The display apparatus of claim 1 , wherein a radius of curvature of the first bent area is less than a radius of curvature of the second bent area.

11 . The display apparatus of claim 10 , wherein, on a plane parallel to the first area and partially overlapping the first area, an extension portion of the cut-off portion within the first area has a shape that is a part of a circle, and a first acute angle between a first boundary line where the first area and the first bent area meet and a tangential line at a first point where the circle and the first boundary line meet, is less than a second acute angle between a second boundary line where the first area and the second bent area meet and a tangential line at a second point where the circle and the second boundary line meet.

12 . The display apparatus of claim 11 , wherein a center of the circle is located outside the first area.

13 . The display apparatus of claim 10 , wherein, on a plane parallel to the first area and partially overlapping the first area, an extension portion of the cut-off portion within the first area has a concave curve shape, and a first acute angle between a first boundary line where the first area and the first bent area meet and a tangential line at a first point where the curve and the first boundary line meet, is less than a second acute angle between a second boundary line where the first area and the second bent area meet and a tangential line at a second point where the curve and the second boundary line meet.

14 . The display apparatus of claim 1 , further comprising a second area separated from the first area, and the first bent area is between the first area and the second area to connect the first area and the second area to each other.
