Abstract

A display apparatus includes a substrate having a bending region between a first region and a second region, the bending region being configured to be bent about a bending axis that extends in one direction; a display unit on the substrate; a first wiring unit at the bending region, the first wiring unit including a first bending portion having a plurality of first holes; and a second wiring unit spaced apart from the first wiring unit and at the bending region, the second wiring unit including a second bending portion having a different shape from the first bending portion.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate comprising a bending region between a first region and a second region, the bending region being configured to be bent about a bending axis that extends in a first direction;
a display unit on the substrate;
a first wiring unit at the bending region, the first wiring unit comprising a first bending portion;
a second wiring unit at the bending region and spaced apart from the first wiring unit along the first direction, the second wiring unit comprising a second bending portion;
a first insulating layer between the substrate and the first bending portion, the first insulating layer comprising an inorganic material; and
a second insulating layer covering the first bending portion and the second bending portion, the second insulating layer comprising an organic material;
wherein a width of the first wiring unit and a width of the second wiring unit along the first direction are different from each other, and
wherein the first bending portion and the second bending portion are located at a same layer.

2. The display apparatus of claim 1 , wherein
the first insulating layer comprises a plurality of inorganic layers.

3. The display apparatus of claim 1 , wherein
the first wiring unit comprises a data line configured to provide a data signal to the display unit.

4. The display apparatus of claim 1 , wherein
the second wiring unit comprises a power line configured to supply driving power to the display unit.

5. The display apparatus of claim 1 , wherein
the first bending portion and the second bending portion each extend in a second direction crossing the first direction on the bending region.

6. The display apparatus of claim 5 , wherein
the second direction is perpendicular to the first direction.

7. A display apparatus comprising:
a substrate comprising a bending region between a first region and a second region, the bending region being configured to be bent about a bending axis that extends in a first direction;
a display unit on the substrate;
a first wiring unit at the bending region, the first wiring unit comprising a first bending portion;
a second wiring unit at the bending region and spaced apart from the first wiring unit, the second wiring unit comprising a second bending portion;
a first insulating layer between the substrate and the first bending portion, the first insulating layer comprising an inorganic material; and
a second insulating layer covering the first bending portion and the second bending portion, the second insulating layer comprising an organic material;
wherein a width of the first wiring unit and a width of the second wiring unit along the first direction are different from each other, and
wherein the first bending portion and the second bending portion are located at a same layer, wherein
the first wiring unit comprises a plurality of first lines and the second wiring unit comprises a plurality of second lines,
and a number of the plurality of first lines is greater than a number of the plurality of second lines.

8. The display apparatus of claim 7 , wherein
a distance between the plurality of first lines is less than a distance between the plurality of second lines.

9. The display apparatus of claim 1 , wherein
the first region has an area greater than that of the second region, and the display unit is located in the first region.

10. The display apparatus of claim 1 , wherein
an upper surface of the first insulating layer on which the first bending portion and the second bending portion are located is flat.

11. The display apparatus of claim 1 ,
an upper surface of the first insulating layer on which the first bending portion and the second bending portion are located is uneven.

12. The display apparatus of claim 1 , further comprising:
a thin film transistor comprising a semiconductor layer, a gate electrode, a source electrode, and a drain electrode,
wherein the first bending portion and the second bending portion comprise a same material as the source electrode or the drain electrode.

13. The display apparatus of claim 12 , wherein
the first wiring unit comprises a same material as the gate electrode.

14. The display apparatus of claim 1 , wherein
the first bending portion and the second bending portion comprise a same material.

15. A display apparatus comprising:
a substrate comprising a bending region between a first region and a second region, the bending region being configured to be bent about a bending axis that extends in a first direction;
a display unit on the substrate;
a first wiring unit at the bending region, the first wiring unit comprising a first bending portion;
a second wiring unit at the bending region and spaced apart from the first wiring unit, the second wiring unit comprising a second bending portion;
a first insulating layer between the substrate and the first bending portion, the first insulating layer comprising an inorganic material; and
a second insulating layer covering the first bending portion and the second bending portion, the second insulating layer comprising an organic material;
wherein a width of the first wiring unit and a width of the second wiring unit along the first direction are different from each other, and
wherein the first bending portion and the second bending portion are located at a same layer, wherein, when an identical current is applied to the first wiring unit and the second wiring unit, the first wiring unit has a first resistance value and the second wiring unit has a second resistance value that is less than the first resistance value.

16. The display apparatus of claim 1 , wherein
the first wiring unit extends towards the display unit along a second direction crossing the first direction.

17. The display apparatus of claim 1 , further comprising first pads and second pads on one end of the substrate, wherein the first wiring unit is connected to the first pads and the second wiring unit is connected to the second pads.
