1. A liquid dispersion of quantum dot particles comprising:
an acrylic monomer medium; and
quantum dot particles dispersed in the acrylic monomer medium having an initial viscosity, the quantum dot particles comprising ligands attached to the quantum dot particles, the ligands comprising functional groups that stabilize the initial viscosity of the liquid dispersion of quantum dot particles to prevent an increase in the initial viscosity that causes gelling of the liquid dispersion of quantum dot particles, wherein the dispersion comprises 5 to 50 weight % quantum dot particles.
