Abstract: A display device includes a substrate, a circuit layer, and a light emitting element layer. The circuit layer includes pixel drivers corresponding to emission areas of a display area of the substrate and electrically connected to light emitting elements of the light emitting element layer, data lines that transmit data signals to the pixel drivers, first dummy lines disposed in the display area and extending in a first direction intersecting the data lines, and second dummy lines extending in a second direction parallel to the data lines and neighboring the data lines on a side in the first direction. A subset of via holes among via holes through which the first dummy lines and the second dummy lines are electrically connected, overlaps one of the emission areas, and another subset via holes are disposed in a non-emission area between the emission areas.
