Abstract: A display panel includes a base layer, a first thin film transistor disposed on the base layer and including a silicon semiconductor pattern, a first control electrode is spaced apart from the silicon semiconductor pattern. A first input electrode is connected to a first side of the silicon semiconductor pattern. A first output electrode is connected to a second side of the silicon semiconductor pattern. The display panel includes a second thin film transistor. An organic light emitting diode includes a first electrode connected to the first thin film transistor, a second electrode, and an emission layer. A first insulating layer includes openings exposing the first side and the second side of the silicon semiconductor pattern, respectively. The first input electrode and the first output electrode are positioned in the openings, respectively.
