APPARATUS OF AIR GAP FORMING FOR PROTECTION COATING OF NANO METAL WIRE GRID AND METHOD THEREOF AND NANO METAL WIRE GRID

摘要

PURPOSE: An air layer formation apparatus for protecting a nano metal wire grid and a method for manufacturing the same are provided to maintain the polarizing function of the grid by heating a deposition source in order to form the air layer. CONSTITUTION: A hemispherical substrate(20) is rotatable by a rotary shaft. Crucibles(31, 32) heat a deposition source in order to form an air layer on a nano metal wire grid. The air layer is formed as a protection coating for the nano metal wire grid. Shutters(51, 52) block the crucibles based on the rotation state of the substrate. The deposition is performed when the slope angle of the substrate ranges between 60 to 85 degrees.
