Abstract: A driving circuit includes: a plurality of scan stages each corresponds to a plurality of scan lines, receives clock signals and a carry signal, and outputs a scan signal; and a plurality of masking circuits corresponding to some scan stages, respectively, among the scan stages. each masking circuit outputs one of the scan signal output from a corresponding scan stage and a first voltage as a masking carry signal in response to a masking signal. A j-th scan stage receives a scan signal output from a (j−a)th scan stage as the carry signal when the (j−a)th scan stage is not one of the some first scan stages, and the masking carry signal output from a masking circuit corresponding to the (j−a)th scan stage as the carry signal when the (j−a)th scan stage is one of the some first scan stages.

Abstract: A stretchable display device includes a display area having stretchable display units each including first islands on which pixels are disposed and first cut-out grooves between the first islands. A peripheral area is adjacent to the display area, the peripheral area includes stretchable peripheral units each including first lines on which driving circuits are disposed and first opening portions between the first lines. A buffer area is disposed between the display area and the peripheral area. The buffer area includes stretchable buffer units each including second islands, second cut-out grooves between the second islands, second lines connected to the second islands, and second opening portions between the second lines. Shapes of the second cut-out grooves may be different from shapes of the first cut-out grooves, and shapes of the second opening portions may be different from shapes of the first opening portions.

Abstract: A display panel includes a base layer including a boundary area and a pixel area, a pixel circuit that overlaps the pixel area, a plurality of insulating layers which includes at least a first insulating layer and in which an opening overlapping the boundary area is defined, a first signal line that is disposed on the first insulating layer and that overlaps the boundary area and the pixel area, an organic layer including a first portion that fills the opening, and a light-emitting element disposed over the plurality of insulating layers and electrically connected to the pixel circuit. The opening includes a first area that overlaps the first signal line and has a first depth and a second area having a second depth greater than the first depth.
