Abstract
A method of manufacturing a holographic pattern-expressing organogel, by using a dithering mask, according to an aspect of the present disclosure includes: preparing a dithering mask including white pixels and black pixels arranged in periodic patterns; photocuring a polymer by passing an ultraviolet ray through the dithering mask; passing a first solvent through the cured polymer; and passing a second solvent through the cured polymer through which the first solvent is passed.
