Provided is a phosphor particle group of divalent europium-activated oxynitride green light emitting phosphor particles each of which is a β-type SiAlON represented by a general formula: Eu a Si b Al c O d N e , where 0.005≦a≦0.4, b+c=12, d+e=16, wherein a mean value of a value obtained by dividing a longer particle diameter by a shorter particle diameter is not greater than 1.75. Also provided are a light emitting apparatus using the phosphor particle group in a light converter, and a liquid crystal display television using the light emitting apparatus. With these, a high-efficiency and stable light emitting apparatus using a β-type SiAlON, and a phosphor particle group therefor are provided. |
