OPTICAL SUBSTRATE, METHOD FOR MANUFACTURING THE SAME AND OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical substrate, a method for manufacturing the substrate and an optical device so as to easily obtain a film pattern. SOLUTION: In the method for manufacturing the optical substrate, a light transmitting substrate 10 is processed in such a manner that a material to form a film 24 is preferentially deposited in a first region 16 while a material to form a film 24 is hardly deposited in a second region 18 compared to the first region 16. Then the material to form the film 24 is selectively deposited in the first region 16.
