The present invention relates to: a dispersion of photonic crystal particles which includes a core-shell particle having an organic core and an organic shell dispersed in a hydrophobic dispersion solvent containing a charge control agent; a preparing method of the dispersion of the photonic crystal particles; and a photonic crystal display device including the dispersion of the photonic crystal particles. The dispersion of photonic crystal particles according to the present invention can be simply produced by dispersing the core-shell particle including the organic core and organic shell in the hydrophobic dispersion solvent containing the charge control agent. 전하조절제를 함유하는 소수성 분산 용매에 분산된, 유기물 코어(core) 및 유기물 쉘(shell)을 포함하는 코어-쉘 입자를 포함하는, 광결정성 입자 분산액, 상기 광결정성 입자 분산액의 제조 방법, 및 상기 광결정성 입자 분산액을 포함하는 광결정 표시 디바이스에 관한 것이다.
