Flexible display device including touch sensor
A flexible display device including a touch sensor is disclosed. In one aspect, the display device includes a flexible substrate, a light emission layer formed over the flexible substrate, and an encapsulation layer formed over the light emission layer and comprising a plurality of encapsulating thin films and a touch detecting layer configured to detect a touch input. The encapsulating thin films include at least one inorganic film and at least one organic film and the touch detecting layer is interposed between a selected one of the at least one inorganic film and a selected one of the at least one organic film that are adjacent to each other.
1. A display device, comprising:
a substrate;
a plurality of first touch electrodes disposed on the substrate and arranged in a first direction;
a plurality of second touch electrodes disposed on the substrate and arranged in a second direction crossing the first direction;
a first protruding portion connected to a first touch electrode, protruding toward an adjacent first touch electrode of the plurality of first touch electrodes, and disposed in a same layer as the first touch electrode;
a second protruding portion connected to the adjacent first touch electrode, protruding toward the first touch electrode, and disposed in a same layer as the adjacent first touch electrode;
a first connection part electrically connected to the first protruding portion; and
a second connection part electrically connected to the second protruding portion,
wherein:
the first connection part and the second connection part are disposed in a layer different from the plurality of first touch electrodes;
the second connection part includes a transparent conductive material; and
the first connection part and the second connection part are substantially parallel to each other and extend obliquely to the first direction and the second direction, and are not connected to each other in the first layer.
2. The display device of claim 1 , wherein the first connection part and the second connection part are symmetrical to each other.
3. The display device of claim 1 , wherein a width of the first protruding portion is greater than a width of the first connection part.
4. The display device of claim 3 , wherein the first connection part contacts and overlaps the first protruding portion.
5. The display device of claim 3 , wherein the first protruding portion is configured to prevent static electricity from rapidly flowing into the first connection part.
6. A display device, comprising:
a substrate;
a plurality of first touch electrodes disposed on the substrate and arranged in a first direction;
a plurality of second touch electrodes disposed on the substrate and arranged in a second direction crossing the first direction;
a first protruding portion connected to a first touch electrode, protruding toward an adjacent first touch electrode of the plurality of first touch electrodes, and disposed in a same layer as the first touch electrode;
a second protruding portion connected to the adjacent first touch electrode, protruding toward the first touch electrode, and disposed in a same layer as the adjacent first touch electrode;
a first connection part electrically connected to the first protruding portion; and
a second connection part electrically connected to the second protruding portion,
wherein:
the first connection part and the second connection part are disposed in a first layer different from the plurality of first touch electrodes; and
the first connection part and the second connection part are substantially parallel to each other and extend obliquely to the first direction and the second direction, and are not connected to each other in the first layer.
7. The display device of claim 6 , wherein the first connection part and the second connection part are symmetrical to each other.
8. The display device of claim 6 , wherein a width of the first protruding portion is greater than a width of the first connection part.
9. The display device of claim 8 , wherein the first connection part contacts and overlaps the first protruding portion.
10. The display device of claim 8 , wherein the first protruding portion is configured to prevent static electricity from rapidly flowing into the first connection part.
