Abstract
The present disclosure provides an organic thin film and a method for preparing the same, a display device, and an optical device, in which the method includes: providing a base substrate; forming an isomerization generating layer on the base substrate, the isomerization generating layer including a first region and a second region; adding a precursor solution on a surface of the isomerization generating layer away from the base substrate, and allowing surface energy of the second region to be greater than surface energy of the first region, so as to form the organic thin film from the precursor solution, the precursor solution being at least partially located in the second region.
