Display apparatus
A display apparatus includes a substrate having a display area with a display device to display an image, and a non-display area around the display area. The non-display area has a bending area bent about a bending axis. An encapsulation layer is located over the display area. A touchscreen layer is located over the encapsulation layer and includes a touch electrode. A touch wire is connected to the touch electrode, and extends from an upper portion of the encapsulation layer, and at least partially into the bending area. A fan-out wire configured to apply an electric signal to the display area and is at least partially disposed in the bending area. The touch wire and the fan-out wire are on different layers from each other in the bending area.
1. A display apparatus comprising:
a substrate having a display area on which a display device is located to display an image, and a non-display area around the display area, wherein the non-display area comprises a bending area bent about a bending axis;
an encapsulation layer over the display area;
a touchscreen layer over the encapsulation layer and comprising a touch electrode;
a touch wire connected to the touch electrode, extending from an upper portion of the encapsulation layer, and at least partially in the bending area;
a fan-out wire configured to apply an electric signal to the display area and at least partially disposed at the bending area; and
an upper organic material layer on the fan-out wire,
wherein the touch wire and the fan-out wire are on the same layer in the bending area, and the upper organic material layer is not on the touch wire, and
wherein the upper organic material layer comprises a first upper organic material layer and a second upper organic material layer on the first upper organic material layer, and the second organic material layer exposes an edge portion of an upper surface of the first upper organic material layer so that a step shape is provided on a side of the upper organic material layer.
2. The display apparatus of claim 1 , further comprising a bending protection layer over the touch wire and the fan-out wire in the bending area.
3. The display apparatus of claim 1 , wherein the fan-out wire comprises a connection wire in the bending area, and an inside wire on a different layer from the connection wire, and the connection wire is connected to the inside wire through a contact hole between the bending area and the display area,
wherein the touch wire continuously extends from the upper portion of the encapsulation layer and is in the bending area.
4. The display apparatus of claim 3 , wherein elongations of the touch wire and the connection wire are greater than an elongation of the inside wire.
5. The display apparatus of claim 1 , wherein the touch wire comprises a same material as the fan-out wire, and resistivity of the touch wire is different from that of the fan-out wire.
6. The display apparatus of claim 1 , further comprising:
an inorganic insulation layer between the substrate and the fan-out wire,
wherein the inorganic insulation layer has an opening or a groove corresponding to the bending area.
7. The display apparatus of claim 6 , further comprising:
an organic material layer in at least a portion of the opening or the groove.
8. The display apparatus of claim 1 , further comprising:
a thin film transistor in the display area and comprising a semiconductor layer, a gate electrode, a source electrode, and a drain electrode,
wherein the touchscreen layer comprises a first touch conductive layer, a first insulation layer, and a second touch conductive layer which are sequentially stacked, wherein the fan-out wire is formed of a same material as and concurrently with the source electrode or the drain electrode, and the touch wire is formed of a same material as and concurrently with at least one of the first touch conductive layer and the second touch conductive layer.
