Abstract: Provided is a mask having a plurality of cell areas, each of which has a plurality of through-portions defined therein. The mask includes a mask film including a polymer and a conductive layer disposed on at least one surface of the mask film and including conductive metal or a conductive metal oxide. Accordingly, precision of a deposition process is enhanced while reducing process time and costs in a manufacturing process of the mask, and thus the yield in manufacturing a display panel using the mask is improved. Therefore, the display panel manufactured using the mask may have improved reliability.
