Abstract:
1. A green phosphor represented by Formula 1 below, wherein in an X-ray diffraction pattern obtained by diffracting the green phosphor with Kα1 of Cu, a first intensity peak is positioned at a diffraction angle (2θ) of 30.5±1.0 and second through sixth intensity peaks are positioned at diffraction angles 24.8±1.0, 32.0±1.0, 35.0±1.0, 39.3±1.0 and 48.5±1.0 degrees, wherein the diffraction angle order does not match the second through sixth intensity peak order: wherein M D is at least one of metal selected from the group consisting of europium, manganese, antimony, cerium, praseodymium, neodymium, samarium, terbium, dysprosium, erbium, ytterbium, bismuth, and any combination thereof, M A is at least one selected from the group consisting of chlorine, fluorine, bromine, iodine, and any combination thereof, and 2.7≦p≦3.3, 0.7≦q≦1.3, 3.5≦r≦4.5, 1.7≦s≦2.3, and 0<x≦0.1.
