Summary: | A metal mask includes a metal panel, provided with an evaporation surface and a back surface opposite to each other and a plurality of through holes extending from the evaporation surface to the back surface. A size of each through hole decreases gradually from the evaporation surface towards the back surface. A first opening is formed by each through hole in the evaporation surface. The first opening includes a primary opening part and a plurality of secondary opening parts. The primary opening part is provided with two long edges opposite to each other and two short edges opposite to each other. The two short edges are connected between the two long edges, and the secondary opening parts are connected at two ends of the long edges. Each secondary opening part has a width perpendicular to the length. A method to produce the metal mask is also provided. |
