    Abstract: A display device is provided. The display device includes first, second and third front signal lines disposed on a first portion and electrically connected to light emitting elements, connection lines overlapping a second portion, and first, second and third rear signal lines disposed on a third portion. The first, second and third front signal lines are disposed on different layers. The first front signal line and the first rear signal line are disposed on a same layer. The second front signal line and the second rear signal line are disposed on a same layer. The third front signal line and the third rear signal line are disposed on a same layer. The connection lines electrically and selectively connect the front signal lines and the rear signal lines.
