A display device is provided including a substrate; a circuit layer; and an element layer. The circuit layer includes a first light emitting pixel driver and a second light emitting pixel driver neighboring each other in a second direction; a third light emitting pixel driver and a fourth light emitting pixel driver respectively neighboring the first light emitting pixel driver and the second light emitting pixel driver in a first direction; and one first-direction line extending in the first direction and adjacent to a boundary between the first light emitting pixel driver and the second light emitting pixel driver and a boundary between the third light emitting pixel driver and the fourth light emitting pixel driver. The one first-direction line includes: a first main extension portion extending in the first direction; and a bypass portion connected to the first main extension portion and bypassing a light transmitting area.
