Abstract: There is provided a display device including a substrate, a circuit layer, and an element layer. A display area of the substrate includes a main display area in which emission areas are arranged side by side, and at least one sub-display area surrounded by the main display area. The at least one sub-display area further includes light transmission areas located between the emission areas. The circuit layer includes light-emitting pixel drivers respectively electrically connected to the light-emitting elements of the element layer, data lines transmitting data signals to the light-emitting pixel drivers, first dummy lines extending in a first direction intersecting the data lines, and second dummy lines extending parallel to the data lines and paired with the data lines, respectively. The second dummy lines include reset transmission lines extending from the non-display area to the at least one sub-display area.
