1. A display device having a display area and a non-display area disposed in a vicinity of the display area and comprising a bending area, the display device comprising:
a substrate;
a third organic insulating layer disposed on the substrate;
an inorganic insulating layer disposed between the third organic insulating layer and the substrate and including an inorganic insulating opening which exposes the substrate;
a first organic insulating layer at least partially filling the inorganic insulating opening and contacting the substrate;
a second organic insulating layer disposed between the third organic insulating layer and the substrate; and
a trench structure disposed in the non-display area, the trench structure comprising an uncovered open top, sidewalls formed by the third organic insulating layer, and a bottom surface located in the bending area,
wherein the bending area is disposed on a side of the display area,
wherein the non-display area further includes a dam area between the bending area and the display area,
wherein a dam portion including the third organic insulating layer is disposed in the dam area,
wherein the inorganic insulating opening overlaps with the trench structure and a width of the inorganic insulating opening is greater than a width of the trench structure,
wherein the display device comprises a first side extending along a first direction and a second side extending along a second direction intersecting the first direction,
wherein the bending area is located in the first direction with respect to the display area,
wherein a length of the bending area is greater than a length of the trench in the second direction, and
wherein a width of the trench, in the first direction, is the same as a width of the bending area, in the first direction.
