1. A display device comprising:
a substrate including a display area in which pixels are disposed and a non-display area;
a common voltage transfer line which is disposed in the non-display area and transfers a common voltage to the pixels;
a data output wire disposed in the non-display area and connected to a data line which transfers a data voltage to the pixels; and
a sacrificial wire disposed between the common voltage transfer line and the data output wire and not connected to the data line; and
a data driver disposed in the non-display area,
wherein the data driver comprises:
a first terminal which outputs the data voltage; and
a sacrificial terminal which applies a predetermined voltage to the sacrificial wire,
wherein the non-display area includes a bending area,
wherein the data output wire includes a first portion extending from the data driver toward the bending area, a second portion connected to the first portion and passing through the bending area, a third portion connected to the second portion and extending toward the display area, and a data contact portion electrically connecting the second portion and the third portion,
wherein a first end of the sacrificial wire is connected to the sacrificial terminal, a second end of the sacrificial wire includes a sacrificial contact portion, and
wherein the sacrificial contact portion includes a dummy wire overlapping the second end of the sacrificial wire and a dummy connection electrode connecting the second end of the sacrificial wire and the dummy wire.
