1. A display device, comprising:
a display panel comprising a display area and a peripheral area at least partially surrounding the display area;
a sensing electrode disposed on the display panel and at least partially overlapping the display area;
a signal line disposed on the display panel, at least partially overlapping the peripheral area, and connected to the sensing electrode; and
an organic pattern disposed on the display panel and at least partially overlapping the signal line,
wherein the display panel comprises:
a pixel disposed in the display area;
a first line pattern at least partially overlapping the peripheral area;
a first encapsulation inorganic layer disposed in both the display area and the peripheral area at least partially overlapping both the first line pattern and the pixel;
an encapsulation organic layer disposed on the first encapsulation inorganic layer and disposed inside the first line pattern; and
a second encapsulation inorganic layer disposed on the encapsulation organic layer, at least partially overlapping the display area and the peripheral area, and being in contact with the first encapsulation inorganic layer in the peripheral area,
wherein the organic pattern comprises:
a first portion disposed beyond the first line pattern; and
a second portion disposed inside the first line pattern and at least partially overlapping the encapsulation organic layer, and
wherein the organic pattern does not overlap the encapsulation organic layer at a highest level thereof, relative to a base layer of the display panel, in a cross-sectional view, and
wherein the first line pattern extends in a first direction, the signal line comprises a first line portion extending in a first direction and a second line portion extending from the first line portion in a second direction crossing the first direction, and the second line portion at least partially overlaps the second portion.
 
19. A display device, comprising:
a display panel comprising a display area and a peripheral area disposed proximate to the display area;
a sensing electrode disposed on the display panel and at least partially overlapping the display area;
a signal line disposed on the display panel, at least partially overlapping the peripheral area, and connected to the sensing electrode; and
an organic pattern disposed on the display panel and supporting the signal line,
wherein the display panel comprises:
a light emitting element at least partially overlapping the display area;
a first line pattern at least partially overlapping the peripheral area;
a first encapsulation inorganic layer disposed in both the display area and the peripheral area and at least partially overlapping the light emitting element;
an encapsulation organic layer disposed on the first encapsulation inorganic layer and having an inclined surface; and
a second encapsulation inorganic layer disposed on the encapsulation organic layer and contacting the first encapsulation inorganic layer in the peripheral area,
wherein the organic pattern comprises:
a first portion that does not overlap the encapsulation organic layer; and
a second portion at least partially overlapping the inclined surface of the encapsulation organic layer and stopping at a top portion of the encapsulation organic layer, and
wherein the first line pattern extends in a first direction, the signal line comprises a first line portion extending in the first direction and a second line portion extending from the first line portion in a second direction crossing the first direction, and the second line portion at least partially overlaps the second portion.
 
20. A display device, comprising:
a display panel including a display area, a non-display area proximate to the display area, and a raised dam disposed within the non-display area and having a substantially closed loop shape;
a sensing electrode disposed on the display area of the display panel;
a sensing electrode signal line electrically connected to the sensing electrode; and
an organic pattern disposed on the display panel and at least partially overlapping the sensing electrode signal line,
wherein the organic pattern comprises:
a first potion disposed beyond the raised dam; and
a second portion disposed within the substantially closed loop shape of the raised dam,
wherein the sensing electrode signal line is disposed beyond the closed loop shape of the raised dam,
wherein the sensing electrode signal line crosses the closed loop shape of the raised dam over an organic pattern that bridges a level of the sensing electrode signal line to that of the sensing electrode, and
wherein the raised dam extends in a first direction, the sensing electrode signal line comprises a first line portion extending in the first direction and a second line portion extending from the first line portion in a second direction crossing the first direction, and the second line portion at least partially overlaps the second portion.
