Abstract: A display panel includes a base layer having a first region and a bent second region. An inorganic layer is disposed on the base layer. A lower groove is formed within the inorganic layer and overlaps the second region. A first thin-film transistor is disposed on the inorganic layer and includes a silicon semiconductor pattern overlapping the first region. A second thin-film transistor is disposed on the inorganic layer and includes an oxide semiconductor pattern overlapping the first region. Insulating layers overlap the first and second regions. An upper groove is formed within the insulating layers. A signal line electrically connects the second thin-film transistor. An organic layer overlaps the first and second regions and is disposed in the lower and upper grooves. A luminescent device is disposed on the organic layer and overlaps the first region.

Abstract: A display panel includes a base layer including a first area and a second area. At least one inorganic layer disposed on the base layer overlaps the first area and the second area. The at least one inorganic layer comprises a lower opening. A first thin-film transistor is disposed on the at least one inorganic layer. The first thin-film transistor includes a silicon semiconductor pattern. A second thin-film transistor is disposed on the at least one inorganic layer. The second thin-film transistor includes an oxide semiconductor pattern. A plurality of insulation layers overlap the first area and the second area. An upper opening extends from the lower opening. A signal line is electrically connected to the second thin-film transistor. An organic layer is disposed in the lower opening and the upper opening. A light emitting element is disposed on the organic layer.
