Abstract
A green emitting phosphor exhibiting an excellent absorption ratio is provided. A green emitting phosphor containing a crystal represented by MGa2S4:Eu2+, wherein M is an element comprising one species or a combination of two or more species among Sr, Ba and Ca, and Eu2+ is a luminescent center, and wherein the particle diameter at 10%, D10, 4.5 μm to 30 μm in the volume-based particle size distribution measured and obtained by the laser diffraction/diffusion particle size distribution measurement method.
