The dummy opening regions are arranged in the first direction in the first side portion of the mask, and are formed therein with openings. The opening regions are arranged in the first direction in a second side portion which is opposite to the first side portion of the mask and correspond to the dummy opening regions, respectively. The number of the openings per a unit area in each of the dummy opening region and the opening region is smaller than the number of the openings per a unit area in the pattern region.
