Abstract:
1. An electrowetting display apparatus comprising: a first substrate comprising a base substrate comprising a plurality of pixel areas, a plurality of pixel electrodes spaced apart from each other and respectively disposed in the plurality of pixel areas, and a hydrophobic insulating layer disposed on the plurality of pixel electrodes, wherein the hydrophobic insulating layer comprises a hydrophobic organic resin and a hydrophobic inorganic particle; a solvent disposed with the hydrophobic insulating layer, wherein the solvent is capable of at least partially dissolving the hydrophobic insulating layer at temperatures at or above a boiling point of the solvent; a second substrate facing the first substrate and comprising a common electrode; an electrowetting layer disposed between the first substrate and the second substrate and comprising a first fluid and a second fluid; and a barrier wall disposed between the plurality of pixel areas and on the hydrophobic insulating layer, wherein the barrier wall comprises a photosensitive resin and an additive.
