1. A display panel comprising:
a substrate comprising:
a base layer;
a plurality of partitioning walls located on the base layer and dividing the base layer into a plurality of pixel regions, wherein each pixel region of the plurality of pixel regions is defined by corresponding two adjacent partitioning walls of the plurality of partitioning walls; and
a plurality of patterns located in each pixel region of the plurality of pixel regions of the base layer, wherein a height of each pattern of the plurality of patterns is lower than a height of each partitioning wall of the plurality of partitioning walls; and
a liquid drop in each pixel region of the plurality of pixel regions,
wherein the liquid drop in each pixel region contacts upper surfaces of the plurality of patterns,
wherein each pattern of the plurality of patterns extends along a straight line extending in a first direction and the plurality of patterns are spaced apart from each other in a second direction, the second direction being different from the first direction, and
wherein the plurality of patterns include neighboring patterns spaced apart from each other at a first spacing and another neighboring patterns spaced apart from each other at a second spacing different from the first spacing.
