Display apparatus
A display apparatus including an organic light-emitting display panel and a touch sensing unit disposed on the organic light-emitting display panel is disclosed. The touch sensing unit includes a touch electrode and a wiring part connected to the touch electrode. The wiring part of the touch sensing unit passes a protruding member disposed on a non-display region of the organic light-emitting display panel, and forms a first wiring part which does not overlap the protruding member, a second wiring part overlapping the protruding part, and a connection wiring part disposed between the first and second wiring parts and having a wiring width less than the first and second wiring parts so as to overlap an edge of the protruding member.
1. A display apparatus comprising:
a base substrate comprising a display region and a non-display region adjacent to the display region;
a circuit layer disposed on the base substrate;
a light-emitting element layer disposed on the display region;
an encapsulating layer disposed on the light-emitting element layer;
a touch sensing unit disposed on the encapsulating layer and comprising a touch electrode and a wiring part; and
a protruding member disposed on the non-display region,
wherein:
the wiring part comprises, when viewed in a plan view:
a first wiring part which does not overlap the protruding member and having a first wiring width;
a second wiring part overlapping the protruding member and having a second wiring width; and
a third wiring part having a third wiring width less than the first and second wiring widths and disposed between the first and second wiring parts;
the first to third wiring widths are widths in a direction perpendicular to an extending direction of the wiring part;
the protruding member is seperated from the touch electrode, and a width of the protruding member in a direction parallel to the extending direction of the wiring part is constant in a region where the protruding member overlaps the second wiring part; and
the extending direction of the wiring part is a direction of extending from the first wiring part to the second wiring part.
2. The display apparatus of claim 1 , wherein the ratio of the first wiring width to the third wiring width is greater than or equal to about 1:0.3 and less than about 1:1.
3. The display apparatus of claim 1 , wherein a length of the third wiring part in the extending direction of the wiring part is in a range of about 5 μm to about 50 μm, inclusive.
4. The display apparatus of claim 1 , wherein the third wiring part comprises:
a first sub wiring part having a wiring width less than the first wiring width;
a second sub wiring part disposed between the first wiring part and the first sub wiring part; and
a third sub wiring part disposed between the second wiring part and the first sub wiring part; and
the first sub wiring part overlaps an edge of the protruding member.
5. The display apparatus of claim 4 , wherein:
a wiring width of the second sub wiring part is increased in a direction toward the first wiring part; and
a wiring width of the third sub wiring part is increased in a direction toward the second wiring part.
6. The display apparatus of claim 1 , wherein the first wiring width and the second wiring width are the same.
7. The display apparatus of claim 1 , wherein the second wiring part comprises:
a first sub wiring part having a first sub wiring width greater than the first wiring width;
a second sub wiring part extending from the third wiring part and having the second wiring width less than the first sub wiring width; and
a third sub wiring part disposed between the first and second sub wiring parts.
8. The display apparatus of claim 7 , wherein the wiring width of the third sub wiring part is decreased in a direction toward the second sub wiring part.
9. The display apparatus of claim 7 , wherein the ratio of the second wiring width to the first sub wiring width is greater than about 1:1 and less than or equal to about 1:2.
10. The display apparatus of claim 1 , wherein:
the protruding member comprises:
a bottom surface;
an upper surface facing the bottom surface; and
side surfaces disposed between the bottom surface and the upper surface;
the side surfaces have an inclination with respect to the bottom surface; and
an area of the bottom surface is equal to or greater than that of the upper surface.
11. The display apparatus of claim 1 , wherein the wiring part comprises:
a first metal layer;
an insulating layer disposed on the first metal layer;
a second metal layer disposed on the insulating layer; and
contact holes disposed between the first and second metal layers.
12. The display apparatus of claim 11 , wherein the contact holes do not overlap the third wiring part.
13. The display apparatus of claim 1 , wherein the third wiring part overlaps around an edge of the protruding member.
14. The display apparatus of claim 1 , wherein the third wiring part overlaps an edge of the protruding member.
15. The display apparatus of claim 1 , wherein the touch electrode is directly disposed on the encapsulating layer.
