Display device

A display device, comprising:

• a substrate including a display region to display an image, a non-display region on at least one side of the display region, an additional region protruding from a portion of the non-display region, and a bent region in the additional region;
• a plurality of pixels in the display region;
• a first insulating layer disposed on the substrate;
• first lines provided between the substrate and the first insulating layer in the non-display region, the first lines extending along the non-display region;
• second lines in the non-display region on the first insulating layer in the non-display region, the second lines being alternately disposed with the first lines;
• a second insulating layer in the non-display region over the second lines and having an upper surface unevenness formed by the first and second lines and including an opening that exposes the substrate of the bent region therethrough;
• a bent insulating layer filling in the opening and including an organic material;
• third lines in the non-display region over the second insulating layer and intersecting the first lines and the second lines in a plan view;
• and
• first insulating patterns disposed on the second insulating layer and between at least adjacent third lines in the plan view, the first insulating patterns to planarize the upper surface unevenness,
• wherein the bent insulating layer and the first insulating patterns are provided on a same layer.
