Abstract: An apparatus for manufacturing metal powder according to the present invention is a metal powder manufacturing apparatus, in which molten metal is broken up, and liquid droplets of the atomized molten metal are cooled by spraying cooling water using a cooling water spraying nozzle provided inside a chamber. The cooling water spraying nozzle is provided such that cooling water is sprayed in a fan shape, and cooling water spraying nozzles provided at different heights have increasing angles of inclination with respect to the inner wall of the chamber as the heights thereof are reduced, thereby decreasing a deviation between flying distances of the molten metal liquid droplets to efficiently manufacture metal powder having uniform properties.

Abstract: This invention relates to a light guide plate and a backlight unit including the same, and more particularly to a light guide plate, which is configured such that a surface layer having desired optical properties and hardness is provided in the form of a thin film on one surface of a substrate layer having excellent optical properties and exhibiting dimensional stability regardless of an external environment, thus manifesting superior processability and scratch resistance and minimizing luminance degradation, and to a backlight unit including the same.
