Claim Text:
1. A thin-film deposition mask, comprising: a mask body, the mask body having a first surface and a second surface that is an opposite surface of the first surface, the mask body having a plurality of deposition holes therein and having spacers protruding from the first surface of the mask body in a vertical direction, the deposition holes being located in an area of the mask body that corresponds vertically to a plurality of sub-pixels disposed on a substrate that receives a deposition material deposited through the deposition holes, the sub-pixels being separated by first and second lanes that intersect and extend between the sub-pixels at angles to each other in respective first and second directions, the deposition holes having a first dimension in the first direction and a second dimension in the second direction, the spacers being located to discontinuously contact the substrate along centerlines of the first lanes extending in the first direction and discontinuously contact the substrate along centerlines of the second lanes extending in the second direction, the spacers having respective contact surfaces for contacting the substrate in the lanes, the contact surfaces having a third dimension in the first direction and a fourth dimension in the second direction, the third dimension being smaller than the first dimension, and the fourth dimension being smaller than the second dimension.
