  • Patent number: 9688911
    Abstract: Provided are an yttrium aluminum garnet (YAG) phosphor, YAG phosphor particles, and methods of fabricating the same. The method of fabricating an yttrium aluminum garnet (YAG) phosphor involves: dispersing aluminum hydroxide core particles in an aqueous solution comprising yttrium, urea, and a lanthanide element to form a shell on the aluminum hydroxide core particles; and calcining the aluminum hydroxide core particles with the shell formed thereon to obtain hollow YAG particles, in which the shell includes a compound of yttrium and a lanthanide element.

  • Patent number: 9051474
    Abstract: An exemplary embodiment of the present invention relates to an anti-glare coating composition and anti-glare coating film having excellent abrasion resistance and contamination resistance. The anti-glare coating composition according to the exemplary embodiment of the present invention comprises a) a binder resin; b) a fluorine-based UV curable functional group-containing compound; c) a photoinitiator; d) a surface curable photoinitiator; and e) a particulate of which a surface has an uneven pattern. In the case where a film is formed by using the anti-glare coating composition according to the exemplary embodiment of the present invention, it is possible to provide both abrasion resistance and contamination resistance by a single coating method, to maintain characteristics of abrasion resistance and contamination resistance when the film is rubbed, and to decrease and easily remove contamination by an oil component, such as a fingerprint mark.

  • Patent number: 8717518
    Abstract: The present invention relates to a polarizer having an antistatic layer and a liquid crystal display. The present invention may provide a polarizer which may prevent malfunction of devices by static electricity generated in preparation or use procedures even without using the ITO layer conventionally formed between the upper glass substrate of a liquid crystal panel and a polarizer in a liquid crystal display for an antistatic purpose, and has excellent physical properties such as endurance reliability under high temperature or high humidity condition and optical characteristics, and a liquid crystal display thereof.
