Abstract
A deposition mask according to an embodiment includes a metal plate including a first surface and a second surface opposite to the first surface wherein the metal plate includes iron (Fe) and nickel (Ni), a thickness of the metal plate is 15 μm to 30 μm, and the metal plate includes a first surface layer having a depth of 20% or less of the thickness of the metal plate from the first surface and a second surface layer having a depth of 20% or less of the thickness of the metal plate from the second surface, wherein when diffraction intensity with respect to a (111) crystal plane of the first surface layer is defined as I (111), diffraction intensity with respect to a (200) crystal plane is defined as I (200), and diffraction intensity with respect to a (220) crystal plane is defined as I (220), a ratio of diffraction intensity of I (220) is defined by Equation 1 below,(220)/((200)+(220)+(111)) [Equation]
