ABSTRACT:
An inorganic thin film polarizer having polarization characteristics comprises: a matrix for thin film polarizer composed of fine columns thereof arranged on a substrate; and light absorbing portions provided on the columns. The columns are made of inorganic substance which is transparent in the desired wavelength region of light such as the visible light region, ultraviolet region and infrared region, and each column has a substantially circular cross section. The columns are tilted at a constant angle with respect to a surface normal of the substrate and has anisotropy in density. The light absorbing portions have a light extinction coefficient larger than that of the columns at the desired wavelength region of light. The columns are arranged at a spacing of from 0.2 to 20 times the diameter of the column.
