Abstract: A display device includes a display panel, a support film, and a polymer layer. The display panel includes a display area comprising a first area that is bendable, and a non-display area adjacent to the display area. The support film is coupled to a bottom surface of the display panel. The support film includes a first groove overlapping with the first area. The polymer layer is disposed in the first groove. The polymer layer includes a material with higher flexibility than the support film. Angles formed by the top surface of the support film and inner sides of the support film defining the first groove are acute angles.

Abstract: A method of manufacturing a superconducting wire is provided. A MgB2 superconducting wire capable of obtaining a stabilizer through an inexpensive process can have high critical current density and magnetic field characteristics without separate plastic. A seamed portion of the wire can be welded to make it possible to plate the wire with conductive materials and inhibit a decrease in quality of superconducting powder. It is possible to obtain a stabilizer without inserting the superconducting powder into a tube.
