Phosphor particle group, light emitting apparatus using the same, and liquid crystal display television

A light emitting apparatus comprising:

• a light emitting element of a gallium nitride-based semiconductor emitting primary light having a peak wavelength of 430-480 nm;
• and a light converter absorbing a part of said primary light to emit secondary light having a wavelength longer than a wavelength of said primary light,
• said light converter including 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:
• EuaSibAlcOdNe, 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, and 0.15≦d and c≧0.3 in the general formula.
