Abstract: A display device can include a first substrate having an active area and a non-active area, where the non-active area includes a plurality of first areas spaced apart from each other and a plurality of second areas disposed between the plurality of first areas. The display device can further include a plurality of first pad electrodes disposed on the plurality of first areas, a plurality of side lines disposed on the plurality of first pad electrodes, and a plurality of step compensation layers disposed in the plurality of second areas. By additionally forming the step compensation layers in the second areas, it is possible to compensate for step differences between the plurality of first areas and the plurality of second areas.
