Abstract: A display device includes a first substrate having a display area, a non-display area surrounding the display area, and a protruding area. A first sensing pad part is formed in the non-display area adjacent to the protruding area. A circuit element layer is positioned in the display area. A display element layer is positioned on the circuit element layer and includes a light-emitting layer and a second electrode on the light-emitting layer. A second substrate overlaps the first substrate and does not overlap the protruding area. A second sensing pad part is formed on the second substrate to overlap with the first sensing pad part. A sealing member is disposed along a border of the second substrate and attaches the first substrate to the second substrate. The first sensing pad part and the second sensing pad part are disposed between a border of the second electrode and the sealing member.
