Abstract

A method for preparing film patterns; firstly, a complementary film pattern () to a desired film pattern () is prepared on a substrate () with an erasable agent; secondly, a whole layer of film () is formed on the complementary film pattern (); and thirdly, the desired film pattern () is obtained by removing the complementary film pattern (). The preparation method can simplify the production process and reduce the production cost of the film patterns.
