Abstract: The present invention provides a deposition mask including: a mask layer having an aperture pattern that is formed in conformity with a transparent electrode to be formed on a display surface of a display panel, with the same shape and size as the transparent electrode; and a support layer having plural support lines formed on one surface of the mask layer across the aperture pattern. In the mask, an arrangement pitch for the support lines of the support layer is set so as to reduce moire fringes or diffraction fringes that appear due to shadows of the support lines, which are transferred onto the transparent electrode as unevenness in deposition thickness.

Abstract: The present invention relates to a method for producing a deposition mask having a structure in which a metal mask sheet with a plurality of opening patterns formed is disposed under tension on and fixed to a metal frame, the method including: a first step of bonding a peripheral part of the metal mask sheet to a synthetic fiber mesh to which constant tension is applied; a second step of cutting off a part of the mesh corresponding to a deposition effective region with a size capable of arranging therein the plurality of opening patterns of the metal mask sheet; a third step of connecting and fixing the frame to the peripheral part of the metal mask sheet on an opposite side to the mesh; and a fourth step of removing the mesh from the metal mask sheet.
