1. A light color conversion layer structure, comprising:
a pixel separation layer over a substrate, wherein the pixel separation layer comprises separating components, and a receiving region over the substrate is defined by adjacent separating components of the pixel separation layer;
a first isolation layer continuously formed over the substrate and on sidewalls of the separating components, wherein the first isolation layer continuously covers an upper surface of the substrate and the sidewalls of the separating components that are adjacent to the receiving region;
a light color conversion unit disposed within the receiving region and on the first isolation layer; and
a second isolation layer disposed on the first isolation layer and the light color conversion unit, wherein the second isolation layer covers the first isolation layer and the light color conversion unit.
