Abstract

A display device includes a substrate including a display area, a non-display area, a first additional area connected to the non-display area at a first boundary, and a second additional area connected to the first additional area at a second boundary, pixels on the display area, an encapsulation film on the pixels, electrodes on the encapsulation film, pads on the second additional area, sensing wires connecting the electrodes and the pads, a first sensing insulating film on the encapsulation film, and a second sensing insulating film on the first sensing insulating film. The substrate includes a curved first side in the first additional area and the first additional area decreases in width from the first boundary to the second boundary, and a boundary of the first sensing insulating film is closer to the first side than a boundary of the second sensing insulating film is to the first side.
