Light Emitting Display Device with Integrated Touch Screen

A display device comprising:

• a substrate including a first area that displays an image and a second area, the second area including an opening in the substrate and a boundary area that surrounds the opening and is between the first area and the opening;
• a dam in the boundary area of the substrate;
• a transistor in the first area;
• a light emitting element in the first area, the light emitting element connected to the transistor;
• an encapsulation unit over the light emitting element in the first area and extending to the boundary area, the encapsulation unit including an inorganic layer and an organic layer;
• a plurality of touch electrodes on the encapsulation unit, the plurality of touch electrodes arranged in a mesh;
• a plurality of touch routing lines that are connected to the plurality of touch electrodes;
• a touch buffer layer between the encapsulation unit and the plurality of touch electrodes, the touch buffer layer extending to the boundary area;
• a first touch planarization layer on the encapsulation unit, the first touch planarization layer overlapping a portion of the dam in the boundary area without being disposed in the first area;
• a touch insulating layer in the first area and the boundary area, the touch insulating layer on the first touch planarization layer in the boundary area;
• and
• a second touch planarization layer over at least a portion of the first touch planarization layer in the boundary area.
