Abstract: Provided is a display device, which includes: a reference voltage line formed along a circular outer line and configured to provide a reference voltage; a first reference voltage auxiliary line electrically connected to the reference voltage line and formed to be parallel with a predetermined interval; and a conductive line forming a contact with the reference voltage line and the first reference voltage auxiliary line and configured to provide the reference voltage to a cathode.

Abstract: Disclosed is a superconducting wire and a method for manufacturing the same, in which spacer are inserted into each space formed between modules, the spacers being different kinds according to a shape of each space when a restacking billet is manufactured in an internal diffusion method for manufacturing a Nb3Sn superconducting wire. One of a copper spacer and a low tin/copper spacer having a sectional area rate of copper/tin more than 6.0 is arranged between three modules as well as between two modules and a diffusion preventing tube, and a high tin/copper spacer having a sectional area rate of copper/tin less than 0.01˜1.5 or a middle tin/copper spacer having a sectional area rate of copper/tin less than 1.5˜6.0 is arranged between four modules.
