Abstract
The main object of the present invention is to provide a method for manufacturing efficiently a pattern formed structure which has a surface having a property-varied pattern and can be used to manufacture a color filter or the like.In order to achieve the object, the present invention provides a method for manufacturing a pattern formed structure, comprising: a patterning substrate preparing process of preparing a patterning substrate having a base material and a photocatalyst-containing property variable layer which is formed on the base material, comprises at least a photocatalyst and a binder, and has a property variable by action of the photocatalyst based on irradiation with energy; and an energy radiating process of radiating energy onto the patterning substrate at an intensity of 0.1 to 10 mW/cm2, thereby forming a property variable pattern in which the property of the photocatalyst-containing property variable layer is varied.
