Abstract: An anti-reflection display window panel and a manufacturing method thereof, which includes: forming a master, wherein a glass or a silicon wafer substrate is subject to light irradiation and etching to form a fine nano-pattern; preparing a nickel core plate to have on its surface the same nano-pattern; preparing an IMD core mold for the anti-reflection by attaching the nickel core plate to a particle plate of a lower mold core in an anti-reflection core mold to expose the surface of the nickel core plate formed with said fine nano-pattern; and, performing an IMD injection molding, wherein molten resin with high temperature is introduced between an upper mold core and the lower mold core and then is subject to the performance of the injection molding with a fast heating and a fast cooling to produce an anti-reflection display window panel formed with the fine nano-pattern for anti-reflection.
