Wire grid polarizer, manufacturing method of wire grid polarizer, optical filter, manufacturing method of optical filter and optical alignment method

摘要: Disclosed is a wire grid polarizer. The polarizer comprises transparent substrate and layer arranged on the substrate, plurality of first polarization areas second are formed portion, sequentially distributed at intervals; polarizationareas internally provided with bars respectively, intervals perpendicular to each other. According an optical alignment method, achieved by using used for method,two directions can be simultaneously defined different film time, preparation process convenient implement, production time saved, cost reduced. invention further relates manufacturing method filter.
