Method of producing layer structure, layer structure, and method of forming patterns

A method of producing a layer structure that includes a first organic layer and a second organic layer, the method comprising:

• forming the first organic layer by applying a first composition including an organic compound on a substrate having a plurality of patterns such that the first organic layer is present inside a gap of the patterns;
• applying a solvent on the first organic layer to remove a part of the first organic layer such that a remaining part of the first organic layer is present inside a part of the gap of the patterns;
• and
• applying a second composition including an organic compound on the remaining part of the first organic layer, wherein the second composition is applied by spin-on coating, and forming the second organic layer through a curing process.
