Abstract: A TFT substrate includes a first active pattern, a first gate insulation, and a first gate. A second gate is on a second gate insulation covering the first gate. A source connection electrode contacts a source region of the first active pattern. A drain connection electrode contacts its drain region. A second active pattern is on a first insulation covering the second gate. A third gate insulation covers the second active pattern. A third gate is disposed on the third gate insulation. A second insulation interlayer covers the third gate. A first source, a first drain, a second source, and a second drain are disposed on the second insulation interlayer. The first source and the first drain contact the source connection electrode and the drain connection electrode. The second source and the second drain contact a source region and a drain region of the second active pattern.

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.
