Abstract: A display device includes a substrate, driving transistors, an insulating layer, and light emitting elements. The driving transistors are disposed in pixel areas on the substrate and each includes a first electrode and a second electrode. The insulating layer is disposed over the driving transistors to cover the first electrodes and the second electrodes of the driving transistors and has contact holes respectively overlapping with the first electrodes of the driving transistors. The light emitting elements are disposed on the insulating layer and include pixel electrodes respectively overlapping with the first electrodes of the driving transistors. In addition, an insulating pattern is disposed in at least one of the contact holes to prevent a corresponding pixel area from emitting light.
