Abstract
A method of fabricating the organic-inorganic hybrid coating layer includes: preparing a gel mixture including an organic precursor and colloidal silica particles; preparing a first mixed solution by heating the gel mixture; preparing a second mixed solution by adding quantum dots to the first mixed solution; and coating the second mixed solution on a substrate and irradiating light thereon to form a polymer matrix in which the organic precursor and the colloidal silica particles are crosslinked, and preparing a coating layer in which the quantum dots are dispersed in the polymer matrix, wherein the organic precursor may include at least one of dipentaerythritol pentaacrylate (DPPA) or dipentaerythritol hexaacrylate (DPHA).
