PREPARATION METHOD OF WIRE GRID POLARIZER USING OBLIQUE ANGLE DEPOSITION AND WIRE GRID POLARIZER PREPARED THEREBY

摘要

The present invention relates to a method for manufacturing a linear polarizing element and a linear polarizing element manufactured thereby, the method can comprising: a substrate preparation step; a substrate installation step in which a substrate holder, formed at an upper portion on the inside of a thin film deposition device, is inclined by a predetermined inclination angle and the substrate is installed on the inclined substrate holder; and an oblique angle deposition step in which a rotary shaft, which is installed on the center of the substrate holder inclined by the predetermined inclination angle with the substrate installed thereon and is able to rotate around the center, is rotated by a predetermined rotation cycle, such that a deposition material may be deposited on the substrate to form a deposition thin film. Therefore, according to the method for manufacturing a linear polarizing element using oblique angle deposition and the linear polarizing element manufactured thereby, a linear polarizing element in the infrared light range can be manufactured only by means of deposition, rather than etching or other methods.
