Abstract
Provided is a mask which includes a mask body having a plurality of through hole portions and including a polymer film and a plurality of magnetic particles dispersed in the polymer film, and a polymer coating layer disposed on an outer surface of the mask body. Accordingly, the time and cost of manufacturing a mask are reduced and the precision of a deposition process is improved as well, so that the manufacturing yield of a display panel using the mask is improved and a display panel manufactured using the same has improved reliability.
