Abstract

Provided is a display apparatus that may minimize the occurrence of defects such as short-circuits during a manufacturing process. The display apparatus includes: a substrate having a bent region located between a first region and a second region and bent in the bent region about a bending axis; an organic material layer located on the substrate to correspond to the bent region and including a second opening or a second groove that extends in a direction that intersects the bending axis; and a first conductive layer extending from the first region through the bent region to the second region and located on the organic material layer.

First claim

What is claimed is:

1 . A display apparatus comprising:
a substrate having a bent region located between a first region and a second region and bent in the bent region about a bending axis; an organic material layer located on the substrate to correspond to the bent region and comprising a second opening or a second groove that extends in a direction that intersects the bending axis; and a first conductive layer extending from the first region through the bent region to the second region and located on the organic material layer.

2 . The display apparatus of claim 1 , further comprising an inorganic insulating layer located on the substrate and comprising a first opening or a first groove corresponding to the bent region,
wherein the organic material layer fills at least a part of the first opening or the first groove.

3 . The display apparatus of claim 2 , wherein the first opening or the first groove overlaps the bent region.

4 . The display apparatus of claim 3 , wherein an area of the first opening or the first groove is greater than an area of the bent region.

5 . The display apparatus of claim 1 , further comprising a second conductive layer electrically connected to the first conductive layer and located in the first region or the second region, and the second conductive layer is located on a layer different from a layer on which the first conductive layer is located.

6 . The display apparatus of claim 5 , wherein an elongation of the first conductive layer is greater than an elongation of the second conductive layer.

7 . The display apparatus of claim 1 , wherein the second opening or the second groove extends in the direction parallel to a direction in which the first conductive layer extends.

8 . The display apparatus of claim 1 , wherein the first conductive layer extends in a zigzag shape from the first region through the bent region to the second region, and the second opening or the second groove extends in the direction parallel to a direction in which the first conductive layer extends.

9 . The display apparatus of claim 1 , further comprising an additional conductive layer located in the second opening or the second groove and spaced apart from the first conductive layer.

10 . The display apparatus of claim 9 , wherein the additional conductive layer comprises a same material as a material included in the first conductive layer.

11 . The display apparatus of claim 9 , wherein the first conductive layer has a structure comprising multi-layers, and the additional conductive layer comprises a same material as a material included in at least one of the multi-layers of the first conductive layer.

12 . The display apparatus of claim 9 , wherein the first conductive layer has a structure comprising multi-layers, and the additional conductive layer comprises a same material as a material included in a lowermost layer of the multi-layers of the first conductive layer.

13 . The display apparatus of claim 1 , wherein the organic material layer further comprises a third opening or a third groove extending along the bending axis.

14 . The display apparatus of claim 1 , wherein the second opening or the second groove does not overlap the first conductive layer.

15 . The display apparatus of claim 1 , wherein a plurality of the first conductive layers are provided, and the second opening or the second groove is interposed between the plurality of first conductive layers.
