摘要： 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.

By using the apparatus for attaching and detaching a cap for optical disc spin-coating, the cap can be easily attached to and detached from the optical disc before and after the spin coating even when the viscosity of the photocurable resin is high. In addition, the use of the apparatus for optical disc spin coating and the method of manufacturing the optical disc results in high manufacturing efficiency.

摘要： An antireflective coating composition includes a hydrolytic condensate (Cl) of alkoxy silane (Cl 1) and fluoric alkoxy silane (C 12); a particle-type metal fluoride (C2) with a refractive index of 1.40 or less; and a liquid dispersion-enhancing chelating agent (C3). A coating film to which the above composition is applied controls refractive index, surface energy, film strength and so on, so it ensures excellent antireflective characteristic, excellent scratch resistance, good erasure of liquid stains such as fingerprints, and particularly excellent dust removal, so it may be usefully applied to an outermost layer of a front surface of a display regardless of kind of a display substrate or presence of an additional coating layer.

摘要： An antireflective coating composition includes a photopolymerizable acrylate monomer (Cl); a particle-type metal fluoride (C2) with a refractive index of 1.40 or less; a photopolymerization initiator (C3); and at least one liquid dispersion-enhancing chelating agent (C4) selected from the group consisting of Mg(CF3COO)2, Na(CF3COO), K(CF3COO), Ca(CF3COO)2, Mg(CF2COCHCOCF3)2 and Na(CF2COCHCOCF3). This composition ensures good mechanical strength, excellent adhesion to a substrate, short curing time by UV curing, prevention of dust attachment, good erasure of stain, good dust removal and good scratch resistance, so it is usefully for making an antireflective coating film of a display.

摘要： In spin-coating a coating solution on a substrate using a conventional spin coating apparatus, the so-called ski-jump phenomenon occurs frequently at an outer edge of the substrate. A spin coating apparatus according to the present invention includes a ring-shaped or polygonal member. An upper portion of the ring-shaped or polygonal member has an inclined portion extending downward and outward, and an inner portion of the inclined portion is adjacent to or in contact with an outer edge of a substrate. An inner side surface of the ring-shaped or polygonal member is inclined downward and outward. When a surface of the substrate is coated with a coating solution using the spin coating apparatus, a ski-jump phenomenon occurring at an outer edge of the substrate can be reduced and contamination of the substrate due to the coating solution can be prevented.

摘要： There is provided an apparatus for optical disc spin-coating, comprising a cap having a tapered protruding portion or a recess in its central lower portion; a turntable for rotation that has a tapered recess or protruding portion formed in an end of its central axis that is inserted into a center hole of an optical disc, wherein the tapered recess or protruding portion of the turntable is coupled with the tapered protruding portion or recess of the cap in a convexo-concave structure; and a vacuum hole formed in an optical disc support of the turntable. When the cap is eccentrically placed on the optical disc, the cap can be easily attached. In addition, the cap can be easily detached from the optical disc by using vacuum pressure. As a result, the operability and manufacturing efficiency can be increased.
