Claim 8:
9. A method of manufacturing a display panel, the method comprising:
preparing a target substrate;
forming and disposing, on the target substrate, a deposition mask having a base with a thickness and a plurality of openings defined therein;
forming, on the target substrate, a plurality of deposition patterns corresponding to the openings; and
removing the deposition mask,
wherein the forming of the deposition mask comprises:
reducing the thickness of a base by wet-etching at least one surface of the base to form a thickness-reduced section; and
forming a plurality of openings by etching a portion of the thickness-reduced section, and

wherein
the base has an upper surface and a lower surface facing the upper surface,
the step of reducing the thickness of the base comprises wet-etching both the upper surface and the lower surface, and
the step of forming the plurality of openings comprises irradiating the upper surface with the laser.
