A display device includes a display panel that includes a substrate, a pixel disposed on the substrate, and an encapsulation layer that covers the pixel, and a touch sensor disposed on the display panel. The touch sensor includes sensing electrodes disposed on the encapsulation layer, and sensing lines respectively connected to the sensing electrodes. Each of the sensing lines includes a first sensing line pattern that extends onto the substrate, a second sensing line pattern connected to the first sensing line pattern outside of the encapsulation region, the second sensing line pattern including a first connection part and a second connection part, and a third sensing line pattern connected to the second connection part of the second sensing line pattern at a lower side of the encapsulation layer
