Abstract: A display device that includes a substrate; a circuit layer; and an element layer. The substrate may include a display area in which emission areas may be arranged, and a non-display area. In order to deliver data signals to data lines at side edges of the display area, bypass auxiliary lines are used that pass through central portions of the display area to allow for a reduced width of the sub area. A horizontal portion of these bypass auxiliary lines may pass over or under other data lines to reach the edge portion of the display. Therefore, a shielding auxiliary electrode may be disposed between the passed over data lines and the horizontal bypass auxiliary lines at locations where these other data lines overlap in a plan view the horizontal bypass auxiliary lines to reduce crosstalk between the horizontal bypass auxiliary lines and the data lines.
