Abstract
The present invention relates to a coating composition for forming an anti-reflective coating layer for a display device, comprising a fluorinated silane with low surface tension, a conductive polymer with antistatic properties, water, and a solvent. Thus, the coating film of the present invention prepared by coating the composition has high anti-reflection, excellent stain resistance to liquid-phase stains such as fingerprints and the solid-phase stains such as dust by controlling the refractive index, surface energy, and conductivity, and thus can be usefully applied to the outermost side of a display device, regardless of the type of substrates such as a Braun tube or a flat display film and the presence of other coating layers such as a hard coating layer and an anti-glare coating layer.
