POLARIZER, METHOD FOR MANUFACTURING THE SAME, AND OPTICAL ORIENTATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a polarizer in which a plurality of thin lines are arranged in parallel, having a mark suitable for inspection and modification of the thin lines, and being capable of assuring precision and quality.SOLUTION: In a polarizer, a plurality of thin lines are arranged in parallel on a transparent substrate having transparency to ultraviolet light. The above problem can be solved by providing a mark having a portion where part of the thin lines is removed and the transparent substrate is exposed in a polarization area where the thin lines are disposed.SELECTED DRAWING: Figure 1
