Abstract
Discussed is a foldable device including a first flexible substrate, a touch unit under the first flexible substrate, a second flexible substrate facing the first flexible substrate, a light-emitting element unit on the second flexible substrate, and an adhesive layer for attaching the first flexible substrate and the second flexible substrate together. The touch unit includes a first touch wiring layer under the first flexible substrate, a first insulating layer covering the first touch wiring layer and the first flexible substrate, a second touch wiring layer under the first insulating layer, and a second insulating layer covering the second touch wiring layer and the first insulating layer. The second insulating layer includes an opening for exposing a part of an edge of the first insulating layer to the adhesive layer.
