1. A display device comprising:
a display panel comprising a display region and a non-display region; and
an input sensing unit comprising:
a sensing pad in a pad region overlapping the non-display region;
a sensing electrode overlapping the display region; and
a signal line electrically connecting the sensing pad and the sensing electrode,
wherein the display panel has a spacer surrounding the display region in a plan view, and defining an opening in which a first portion of the signal line is located, the first portion of the signal line having a greater width than a second portion that is not located in the opening defined by the spacer.
 
16. A display device comprising:
a display panel comprising a display region and a non-display region; and
an input sensing unit comprising:
a sensing pad in a pad region overlapping the non-display region;
a sensing electrode overlapping the display region; and
a signal line electrically connecting the sensing pad and the sensing electrode,
wherein the display panel comprises a base layer,
a circuit layer on the base layer, and comprising insulating layers,
a light-emitting element layer on the circuit layer, and comprising a pixel defining film and a light-emitting element,
a dam having a first portion overlapping the signal line, and a second portion not overlapping the signal line, and
a spacer on the pixel defining film,
wherein the first portion of the dam comprises a first layer comprising a same material as at least one of the insulating layers, a second layer comprising a same material as the pixel defining film, and a third layer comprising a same material as the spacer,
wherein the second portion of the dam comprises a first layer comprising the same material as the at least one of the insulating layers and a second layer comprising the same material as the pixel defining film,
wherein the second portion of the dam does not include a third layer comprising the same material as the spacer, and
wherein a first line portion of the signal line overlapping the first portion has a greater width than a second line portion adjacent to the first line portion.
