Abstract
A display panel includes a first substrate and a second substrate assembled together, a display medium layer between the first and second substrates, a sealant between the first and second substrates and surrounding the display medium layer, a first alignment layer between the first substrate and the display medium layer, a second alignment layer between the second substrate and the display medium layer, and a hydrophobic surface. One of the first alignment layer and the second alignment layer has an individual central portion. The hydrophobic surface extends from an edge of the individual central portion toward an edge of the one of the first substrate and the second substrate. The sealant at least extends between the hydrophobic surface and the edge of the one of the first substrate and the second substrate. The hydrophobic surface includes a hydrophobic material that is more hydrophobic than the individual central portion.
