▎ 摘  要

NOVELTY - The display panel has a flexible substrate (1140) including a hard portion (1141) and a soft portion (1142). A data line (112) is positioned on the soft portion and having a curved shape on the soft portion. A gate line (113) is positioned on the soft portion and having a curved shape on the soft portion. A light emitting device has a first electrode positioned on the hard portion. A light emitting layer is positioned on the first electrode, and a second electrode positioned on the light emitting layer. A protective layer is positioned on the light emitting device and encapsulates the light emitting device. A graphene layer is positioned on the protective layer and has graphene oxide. A pressure-sensitive adhesive layer is positioned on the graphene layer and including a pressure-sensitive adhesive. A polymer film is positioned on the pressure-sensitive adhesive layer and has an elastomer. USE - Display panel of display device (claimed) such as plasma display device, and organic light emitting display device. ADVANTAGE - The device can be stretched and has a thin bezel while having excellent moisture permeability resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a display device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the display panel. Pixel (111) Data line (112) Gate line (113) Flexible substrate (1140) Hard portion (1141) Soft portion (1142)
