Abstract: In an alloy metal plate according to an embodiment, diffraction intensity of a (111) plane of the alloy metal plate is defined as I (111), diffraction intensity of a (200) plane of the alloy metal plate is defined as I (200), diffraction intensity of a (220) plane of the alloy metal plate is defined as I (220), a diffraction intensity ratio of I (200) is defined by the following Equation 1, and a diffraction intensity ratio of I (220) is defined by the following Equation 2. At this time, the A is 0.5 to 0.6, the B is 0.3 to 0.5, and the value A may be larger than a value B.
A=I(200)/{I(200)+I(220)+I(111)} [Equation 1]
The diffraction intensity ratio of I (220) is defined by the following Equation 2.
B=I(220)/{I(200)+I(220)+I(111)} [Equation 2]
In addition, in an iron (Fe)-nickel (Ni) alloy metal plate of a deposition mask for OLED pixel deposition according to an embodiment, the metal plate is formed of a plurality of crystal grains, and the maximum area of the crystal grains measured over the entire area of the metal plate is 700 μm2 or less.-
