1. A display device, comprising:
a display panel including a display region and a non-display region adjacent to the display region; and
an input sensing unit disposed on the display panel and including an active region overlapping the display region and a peripheral region overlapping the non-display region,
wherein the display panel comprises: a base layer; a circuit element layer disposed on the base layer and comprising a plurality of insulating layers and a voltage line disposed on any one of the plurality of insulating layers; and a display element layer comprising a pixel defining film and a light-emitting element,
wherein the light-emitting element comprises: a first electrode; a second electrode opposite to the first electrode; and at least one organic layer disposed between the first electrode and the second electrode,
wherein the at least one organic layer comprises: a first portion overlapping the display region; and a second portion at least partially overlapping the non-display region,
wherein the non-display region comprises a connection region in which the voltage line is disposed,
a first opening is formed in the second portion, the second electrode and the voltage line are directly connected to each other through the first opening, and at least one first trace line of a plurality of first trace lines overlaps a part of the voltage line at the bottom of a through-hole on a plane,
the through-hole overlapping the first opening is formed in the connection region; and
at least some of the plurality of first trace lines overlap the through-hole;
wherein the input sensing unit comprises: a plurality of sensing electrodes overlapping the active region; and the plurality of first trace lines are connected to some of the plurality of sensing electrodes and are partially overlapping the active region, wherein at least some of the plurality of first trace lines overlap the first opening on a plane.
