Abstract: PURPOSE: A green phosphor with superior color purity, a light emitting device with excellent color reproducibility and color rendering, a display device, and an illumination device are provided to enhance color purity and to obtain high brightness. CONSTITUTION: A green phosphor includes M element, Al element, silicon, oxygen and nitrogen as parent components and one or more rare earth materials as dopant. Here, M indicates one or more elements selected from a group consisting of Mg, Ca, Sr and Ba, and the rare earth element is selected from a group consisting of Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm and Yb. If the maximum intensity diffraction peak at the X-ray diffraction pattern is 100%, the relative intensity of 2Θ has the diffraction peak of greater than 20% in a range of 29.0-30.5 degrees and 31.0-31.5 degrees.

Abstract: PURPOSE: A light emitting device package and a lighting device with the same are provided to emit light of various colors by replacing a light conversion plate in the light emitting device package, thereby emitting various light emitting colors by a single light emitting device package. CONSTITUTION: A main body(10) includes a cavity(11) and a receiving groove(13). A light emitting device(20) is arranged in the cavity. A light converting unit(30) is arranged on a light route. The light converting unit includes at least one light converting plate(31,32,33). A driving unit rotates the light converting unit so that the light converting unit is included in the receiving groove.
