Coating pattern formation method, coating pattern formation device, and coating-patterned substrate

A coating pattern formation device comprising:

• a lyophilicity adjuster configured to adjust lyophilicity of a pattern region provided on a substrate;
• and
• a coating component configured to form a coating pattern having a shape of the pattern region by applying a coating liquid to the pattern region,
• the lyophilicity adjuster being further configured to adjust the lyophilicity of the pattern region such that the pattern region is divided into a plurality of small pattern regions in at least one division direction, such that adjacent small pattern regions have different lyophilicity, a small pattern region spaced away from an end of the pattern region has the lowest lyophilicity among the small pattern regions in the at least one division direction, and such that the lyophilicity of the small pattern regions increases from the small pattern region having the lowest lyophilicity toward the end of the pattern region.

A coating-patterned substrate comprising:

• a substrate having a surface with a pattern region;
• and
• a coating pattern disposed on the pattern region of the surface of the substrate,
• the pattern region being divided into a plurality of small pattern regions in at least one division direction, with adjacent small pattern regions having different lyophilicity,
• a small pattern region spaced away from an end of the pattern region having the lowest lyophilicity among the small pattern regions in the at least one division direction, and
• the lyophilicity of the small pattern regions increasing from the small pattern region having the lowest lyophilicity toward the end of the pattern region.
